Hi fellas,

Dale Adams (DVDO/Anchor Bay tech) has suggested that we try to compile a list of native resolution timings and accumulate them in a single spot. As this subject is relevant to many folders but of paramount interest to us, at the video processor forum, I thought we could start here.

We should state the type of display and the type of device that was used to accumulate it, as well as the connection used..

Let me start with my own display:

NEC 42MP2 853x480
DVI timing (iScan HD) @ 59.94Hz:
HShift=139
HSize=854
HFront=15
HSync=80
HBack=139

VShift=1
VSize=480
VFont=1
VSync=5
VBack=37

For those with Mitsubishi PD5010, Marantz PD5010, or NEC 50MP2 plasma displays, here are the timings I am using via DVI;

H-shift=256
H-size=1360
H-front=64
H-sync=112
H-back=256
total= 1792

V-shift=3
V-size=768
V-front=3
V-sync=6
V-back=18
total=795

Plasma MUST be first adjusted using the analog connection and set to"wide2." Make all your adjustments to the Iscan timings, then:

Switched to DVI while switching the corresponding output on the Iscan. Only minor adjustments can be made while using the DVI input on the plasma, any major changes to the timings forces the Mitsubishi back into trying to scale the image. When this occurs the image is changed by the Mitsubishi to 1280x768, regardless of what you feed it via the Iscan. I suspect the Marantz and NEC models will do the same.

Do you think the NEC 50 inch will/should work for the NEC 61 MP1 ?
Will these work in a CS-2 ?

Here are the parameters I used to get 1:1 mapping on the Fujitsu P50HXA10US we have in our lab:

H-Shift 144
H-Size 1360
H-Front 176
H-Sync-112
H-Back 144
H-Total 1792

V-Shift 8
V-Size 768
V-Front 8
V-Sync 6
V-Back 13
V-Total 795

The P50 will only give 1:1 mapping at a resolution of 1360x768, even though its native resolution is 1365x768. Also, this only works at 60 Hz. As nearly as I can determine, the P50 cannot do 1:1 mapping at 50 Hz.

Note that these are not the only parameter settings which will give you 1:1 mapping. The P50 appears to have a tolerance range around many of these settings which still gives you 1:1 pixel mapping. When adjusting a setting, I sometimes notice that nothing happens for many adjustment steps, and then the P50 will sort of snap into a different mode. On some of these you may need overshoot the setting slightly to get the P50 mode change, and then back it off a bit.

Other settings appear to be interactive. I.e., you can't get one right until you have one of the others correct. The horizontal scan rate is one of these. If you're too far off on the scan rate, then you may have trouble with the horizontal size.

These timings were produced with an iScan HD, but I see no reason why they shouldn't work with any source capable of fine-grained timing adjustments.

This was the same for the Mitsubishi. It synced only at 1360x768 with 3 unused rows on the left and 2 on the right. And, it only synced at 60hz. I was able to get it to sync 1:1 on the analog connection at 1365x768, but it was not nearly as stable as that of the DVI.

I too noticed many of the settings had little affect on plasma, I had to make rather major adjustments as Dale said, then back them down to find the right setting. This was most noticeable with framerates.

Hard to say, the native rate is the same, but plasmas act so differently from one another. Take a look at Dale's settings on the Fujitsu and mine on the Mitsu. They both have the same native rate, but the settings are quite different.

Look at the owner's manual for the NEC and read the page on computer resolutions accepted, and what the plasma must be set to in order to accept each. You will note that it must be set to a certain screen format in order to display at it's native rate, ie, wide, true, full, etc. All depends what NEC calls their different screen formats.

Hi,

Sony HS20 setting wanted, please.

Does anyone have a detailed setting for the Series 6 Panasonic 50"ers? I believe all models (PHD6 et al) are identical, so any info would be greatly appreciated.

I ask particularly because I have a real suspicion that the panels are not true 1366x768 displays, as I have not been able to get accurate 1:1 pixel mapping at that resolution (on a 50PHD6 panel). The inflexibility of the series 6 DVI input is also a real headache.

Anyone?

These displays are 1366x768 pixels, you can connect a PC and count 'em yourself.

I have found the best way to connect DVDO iScan HD to my display is via analogue: this is because the display supports 48Hz, 50Hz and 60Hz (and variations thereof) at native resolution via analogue and is not limited to 60hz like DVI.

Once 1:1 pixel mapping is achieved, via adjusting the screen's horizontal/vertical size/position, the picture quality of analogue (be it on iScan HD or my HTPC) is almost indistinguishable from DVI even close up. Furthermore, at my seating position of 4m or so one can not see any difference in signal quality at all.

Judder is still visible though, and I don't want to be converting all my 50Hz material to 60Hz. :) Which is also why I used iScan HD's excellent 48Hz output for my Region1 movies: no nasty 3:2 pulldown judder.

Panasonic 50" Plasma @ 48Hz, 50Hz, or 60Hz (and +/- variations) via analogue connection:

H-shift=256
H-size=1366
H-front=64
H-sync=112
H-back=256
total= 1798

V-shift=3
V-size=768
V-front=3
V-sync=6
V-back=18
total=795

These are the "out the box" settings and they work perfectly.

DVI
DVI is notoriously difficult on Panny plasmas, with the board supporting:
480p, 720p and 1080i @ 60Hz
576p @ 50Hz

1366x768 @ 60Hz is also listed (as is 852x480 @ 60Hz for SD panels) as working out the box but some people have trouble getting this to work properly. I'll see if I can find some timings for DVI too @ 60Hz too.

StooMonster

Thanks a million, StooMonster.

I'll look out for the DVI settings if you can get 'em. Incidentally, analogue out of the box 1366 res doesn't work for me unfortunately. I have to alter the H+V positioning considerably to center the picture (without any stretching on the plasma side). Even then, there is a thin 'dead' border around the image (all sides), which is what lead me to suspect the panel as not being a true 1366X768 (perhaps a few pixels more on each side). This is the case whether in video output or test pattern display.

I'm a bit confused :confused: ...BTW, I can confirm firsthand that the DVI input takes native res - 1366X768 @60Hz - I've tried it with a CenterStage CS2. However, for some reason, it will only take XGA from the iScanHD - not native res. ANalogue works fine at all resolutions and refresh rates...

Any ideas??

DVDO iScan HD is ideal because of the excellent test patterns, and I have similar ones to set up my HTPC.

Set the iScan HD to default timing setting for 1366x768, then adjust the horizontal/vertical size/position on the plasma display; it's really easy on Panasonic plasmas (unlike the Pioneer ones for example).

Getting 1:1 match on analogue VGA is really easy, three simple steps:

1. Use horizontal size control on |||| test pattern until the "rainbows" go away, they are different colour interference patterns as you pass the centre position (either getting horizontally bigger or smaller); in centre setting there is no interference pattern.

2. Use vertical size control on === test pattern until the "rainbows" go away and you've got solid black'n'white lines.

3. Use horizontal an vertical position on iScanHD's first test pattern until image has single pixel white line round the edge.

This takes seconds: one-to-one pixel match is demonstrable on every test pattern.

NOTE:

The screen has a number of "memories" for different resolutions/refresh rates set to it, once you've done this once it stays.

Super-Advanced Users do this within the Service Menu so that once the horizontal/vertical size/position is set to 1:1 match it becomes the "normalize" setting in the "Picture Position" menu.

As I said above this is with analogue, the DVI does not let you do this. DVI really is poor on Panny plasmas, but their analogue is stunning and the PQ once one-to-one set is almost indistinguishable from DVI -- they must have good ADCs or over-sample or both :).

Black borders
Once you have 1:1 match on screen with test patterns you may still see black borders with some video sources: typically thin at top and bottom and fatter at the sides, the edges may even be blurred or wavey. This is where the source isn't using the entire bandwidth available to it, however, this is solved simply with "Overscan" setting that can be increased until the image files the entire 1:1 matched display.

Pioneer 50" MEX plasma
I've also set up analogue and DVI with one of these plasma screens. Again timings were straight out the box defaults for the native 1280x768 pixel resolution, but the challenge here is the internal frame buffer of the screen is fixed to 70Hz.

Via analogue this was a simple fix with iScan HD because we set PAL and NTSC material to Frame Rate Adjust to 70Hz; DVI was more of a problem because it would only accept 60Hz, and then it's internal frame buffer converted it to 70Hz.

Still, both analogue and DVI were 1:1 matched at 1280x768.

Again with these Pio screens I'd recommend analogue connection because of the ability to display the native resolution at the plasma's fixed internal refresh rate.

HTH.

What about the new 4340 and 504 PIO? Does it also only do 70hz frame buffer?

Thanks

I am afraid that I have no idea Oliver, because for Pioneer plasmas I only have access to my friend's 50" MXE display, which is why I was able to judder-test only that model.

We ran judder tests via analogue and DVI using the PC judder-test program, the quest to find the Pio's Frame Buffer Hz of the was the inspiration for suggesting to DVDO that iScan HD should have a judder-tester.

Sorry I can't help more, hopefully someone will post Frame Buffer results as well as settings.

I believe that you need to go to 72 Hz (NTSC) or 75 Hz (PAL) on DVI to be able to get rid of the problem with 70Hz. However I can not tell if that will help, I think one needs to go into 72.001 or something close to that to be able to get the 503MXE (503CMX in US) to work properly. Anyway you definitly needs to go above 70 Hz.

Okay, we could only get a picture on DVI at 60Hz and just blank screens at 72Hz and 75Hz etc.

However, even if you can input higher refresh rates via DVI, won't they still be downconverted to 70Hz by the internal frame buffer like the analogue signals are?

Next time I visit my friend, we'll recheck again. :)

StooMonster

StooMonster: I think you need to get the refresh more like 71.928 or 71.923. Some information can be read in this thread:
http://www.avsforum.com/avs-vb/showthread.php?s=&postid=2361301#post2361301

However, I can not say what is needed for PAL material, I have it written down somewhere - I just can't find it.... So 75 Hz might do it, it may not.

There might stil be problems with a couple of frames/movie beeing handeld badly, but nothing big.........

you guys are all way out of my league...which is good because maybe you can help. Looking for whatever information I can get on anyone's experience on getting 1:1 mapping with a Sony 50" plasma. I have the new KE50XS910, which is aimed for consumer HD use. Because of this it's almost impossible to get any technical data, along with the fact that has only been out a couple of months. I believe it uses the same panel as the high end Sony 50" XBR.

Any thoughts on what to try to accomplish 1:1 would be greatly appreciated!

thanks!

Exactly the same idea as Stoomonster's 50" settings, but using the 852x480 default option (PLA1)

I actually prefer the 720P option via analogue (but that's not native res ;))

DVI native for the PWD6 is a bit of a nightmare, best go analogue as Stoo mentions...or even better 720P

JJ

jasonjo,

I have just tested my original numbers with a new 42VP4 (just upgraded last night). The originals work, but with some tweaking (852x480 instead of 853x480).

One interesting issue, however, is that the unit will only accept native resolution if you select RGB mode as WIDE1. Wide2 setting cause it to interpret the signal as 848x480 (there are a few other settings, but they result in stuff like 640x480 or 720x480).

Regarding analog & oversampling. If you provide an analog input with a signal it can cleanly oversample and downscale - you'll get a good image. I do the same with my display (analog for PAL) using 768P instead of native 576p (using the Lumagen vision Pro). I found this to resolve a few issues in both the scaler and the display. As the display is capable of sampling this resolution quite easily, this simplifies things without significantly affecting picture quality. A lower resolution than the internal scaler allows would cause double upscaling, which is bad (increases artifacts significantly). However, downscaling is much simpler to do than upscaling.

Even badly done downscaling can appear pretty good in many situations...

Has anyone managed to get the Panasonic 50" 6 series working at 1:1 via DVI yet?

Looking for 1366 x 768, I realise this will have to be at 60/59.94Hz

I need:
V Sync, V Front, V Total, H Sync, H Front and H Total, also the plasma serice menu settings for H Pos/V Pos/H Size/V Size.

I've tried to get it to work but I end up with the image shifted so far over that I can't get it centered using scaler or plasma controls??

Cheers

Check the main Iscan HD thread on this, maybe around page 65 or so. I know someone else asked this question and got a reply. You can also do a search in that particular thread. Good luck

Thanks for the reply, had a look and I do remember the thread, however that was regarding the iScan HD inparticular and the Fuji 50", I know that the Fuji and the Panasonic use the same glass but the electronics will be different. So does anyone have Panasonic 50" 6 series details, and if possible from one of the new Lumagens??

Cheers

Dale (or any other knowledgeable member):

You mention the 1:1 mapping parameters for the iScan HD and the Fujitsu P50XHA10US.

I have an iScan HD and the Fujitsu P55XHA30WS. I've read similar things about this panel and the one you calibrated. A few questions:

1. Would you use the DVI or the component output of the iScan HD? I'm running SDI out from my DVD player to the iScan HD SDI input, and my inclination is DVI, but I wonder if there are any known setup shortcomings of DVI on this monitor.

2. Should I start with the same parameters you used to achieve 1:1 and tweak from there, using the advanced menu options you've set? I read in an article that the max res of my panel (like yours) over DVI was 1360X768, not the physical res of 1366X768.

3. Can you give me the best method/tips for achieving 1:1 pixel mapping using the iScan HD if (2) isn't a good idea? I'm willing to tweak myself, but a little bit of wisdom would save me time. Do I have to switch back and forth between TP 1-3 and the adjutment parameters??? What do I look for, and are there any other things (order of adjustment, weird behavior, etc.). Again, I believe my set and yours should behave similarly.

4. How about FRC? Should I try to tweak this for 60Hz 3:2 pulldown? Does DVI vs. Component likely make a difference in available FQ states (e.g. 48 and 72Hz or Unlocked)? If I'm looking at TP6 for adjustment, am I able to see how it would behave for a 3:2 vs. 2:2 60Hz source? I assume all my NTSC sources will be 60Hz ....

I know that's a lot - but your help woud be appreciated!

-Adam

Just wanted to let any other folks hear about my experience getting 1:1 with the iScan HD and the Fujitsu P55XHA30WS over DVI (the 55" model).

All you need to do is:

1. Make sure Screen Orbiter is OFF
2. Make sure the Fujitsu is set to DVI-2 (for video), and DVDO output is set to DVIV.
3. Set the user mode to advanced
4. Use the same settings Dale from DVDO used for the 50" Fujitsu, which are:

H-Shift 144
H-Size 1360
H-Front 176
H-Sync-112
H-Back 144
H-Total 1792

V-Shift 8
V-Size 768
V-Front 8
V-Sync 6
V-Back 13
V-Total 795

If things look freaky as you're changing the settings, don't dispair - it WILL snap into the perfect 1:1 once you nail the numbers.

You WILL only be able to use 60Hz lock for 60Hz sources. Other FRC's don't work at 1:1, but I see no judder from 60Hz film sources.

You can confirm the resoultion in the INFO window which will show you 1360X768. That means 3 unused pixels on the left and right. You can see in Test Pattern 3 that ever square in the checkerbox is a perfect pixel, no more and no less.

I use an SDI-modded Denon 3910 to the SDI input of the iScan HD, and found you need to use an SDI line offset value of 13. Also, I needed to set overscan by 1, and then Horizontal Pan by 2 to get the image dead-on perfect.

Now, it's a totally amazing image. Definitely worth it, in my book.

I've got the iScan HD on loan and will switch it out for an HD+ in a month or so - will report back then if I notice any config differences (doubt it), and how it looks with HD DVI HDCP input sources at 1:1.

Hope that helps someone else!

Anyone using a Mitsubishi Medalion 1080?

oferlaor,
I'm using DVI cable from Vision HDP to 42VP4. What is the best resolution and set up method? Please provide me a detail/step.
Thanks a bunch.

ex-airforce,

852x480p @ 59.94Hz is your best choice - you'll can obtain native resolution that way.

Thanks to Edaly (I think these are slightly different than StooMonster):

Panasonic 50" plasma DVI:

Horizontal: 48.36Khz
Vertical: 60Hz (not 59.94!!)
Dot Clock freq: 86.75Mhz

If someone has the settings for getting 1:1 pixel mapping on the Sony KDF70XBR950, could they please post them? TIA

swatter911,

With the 70 XBR you will have a fun time. Choose a scaler other the FE. One that has the ability to change the frequency like a computer. Then go over to the HTPC forum and look at people that have don e it with the Wega (XBR should be the same as 1:1 as documented by some). Once in the HTPC forum look through the service menu tweaks w/o them it won't work. Than after the tweaks use others resolutions as a guide. I have not seen true 1:1 at the "native resolution" but many have achieved 1:1 at a little smaller resolution. The reason I say a no go on FE is that I have a customer with the 60" XBR and CS2 and I am going to their house 45 miles away to switch from DVI output to Component via VGA (Looks worse than DVI by a long shot) just to stop the unit from having the picture roll. If you turn it off and on it works fine but its changing sources. something like the lumagen with genlock would probably work.

I sent an email to NEC technical support. About 3 weeks later someone answered with the 1360 and 1365 timings. I could not get the timings to work at 1365, but they worked perfectly at 1360 (with the exception of 5 columns of pixels that show no picture).

I put a link to the thread with all this information, including pdf files of the timing parameters.

NEC thread with timing information (http://www.avsforum.com/avs-vb/showthread.php?s=&threadid=472203)

I tried these numbers, but couldn't get a stable signal on my Panasonic 50PHD7UY on my new iScan HD+. Does anyone out there have stable 1:1 settings for this set?

HI Gang...

I have finally figured out how to dial in the NEC HT1000 1024x768 DLP for 1:1 over DVI with Iscan HD. Whew! I knew I had to be doing something wrong.

The HT1000 can be pixel mapped in (3) screen modes: 4:3, 16:9 & Anamorphic


HT Screen Mode - 4:3
HT Overscan - 0%
HT Aspect - Normal, no others
Iscan Format - XGA 1024x768 - all parameters at factory
hshift 160 vshift 3
hsize 1024 vsize 768
hfront 24 vfront 3
hback 160 vback 28
htotal 1344 vtotal 805
Frame Rate - 60hz

HT Screen Mode - 16:9
HT Overscan - 0%
HT Aspect - Normal & Full, no others
Iscan Format - 1024x576 - all parameters at factory
hshift 136 vshift 3
hsize 1024 vsize 576
hfront 40 vfront 5
hback 96 vback 16
htotal 1296 vtotal 600
Frame Rate - 60hz

HT Screen Mode - Anamorphic
HT Overscan - 0%
HT Aspect - Full, no others
Iscan Format - XGA 1024x768 - all parameters at factory
hshift 160 vshift 3
hsize 1024 vsize 768
hfront 24 vfront 3
hback 160 vback 28
htotal 1344 vtotal 805
Frame Rate - 60hz

The problems I initially had with the HT1000 had to do with the projector overscan setting being anything but 0%, and then making sure the HT1000 Aspect Ratio was properly selected.

Now all of the pixel mapping patterns are perfectly clean.

Here are my numbers for a Panasonic 50PHD7UY Plasma display at 1366x768. These numbers work great with an iScan HD+, but should work with other scalers as well.

H-Size: 768
H-Front: 34
H-Sync: 112
H-Back: 282
H-Total: 1794

V-Size: 768
V-Front: 3
V-Sync: 4
V-Back: 31
V-Total: 806

NB: H-Shift and V-Shift are just easy ways to adjust the Front & Back numbers at the same time. So, don't input the "Shift" parameters at first, then use them later with the Frame Geometry test pattern to make sure you get the positioning exactly right. (there should be a 1 pixel border around the whole frame in Frame Geometry).

Errr...sorry for reviving a thread that's been 8 months dormant, but I looked up this thread as well as the Official Pioneer plasma TV thread and I still can't find the info I need.

I have a 4th generation Pioneer screen (the 4345) and I am awaiting the arrival of my iScan HD+.

I intend to use component cables from my 59avi into HD+ (to bypass HDCP), then go the VGA route from HD+ into my Pioneer Media Receiver (so that the 768p 72hz signal from the HD+ drives the plasma screen natively, or so I hope). Unfortunately the HDMI input accepts only 50hz and 60hz signals.

What are the timing settings to get a 1:1 pixel mapping for my screen? The native res of the screen is 1024 X 768.

Does anyone has the timing settings of Sanyo Z1 (or the Matinee HD1) projector? The native resolution of the screen is 964x544. Thank you.

I have a TH-50PHD7UY with an HDMI board inputting at 60Hz. As I recall vertical was fine (as tested with the horizontal line pattern)--I didn't need to change anything other than probably shift the picture a little. Horizontal was also very close and there are a number of ways of fixing it; the total is what I think really matters. My settings are:

H-Front: 36

Settings for a Sony KDE50 XBR950?

Manual says it only accepts 480i/p, 720p, and 1080i.

Thanks

What about settings for my SAMSUNG PS-42D5SX?
Manual just reports the main spec, which are:
native resolutions at
848x480@60Hz (WVGA): Vfreq=60.000 Hfreq=31.020 Vpolarity=p Hpolarity=p
848x480@75Hz(WVGA): Vfreq=74.769 Hfreq=37.684 Vpolarity=p Hpolarity=n

How can I set all the other parameters in the xconfig file?

Thank u all a lot.

Can someone give me the timings for a Pioneer 50" HD1000? Thank you.

I tried these numbers, but couldn't get a stable signal on my Panasonic 50PHD7UY on my new iScan HD+. Does anyone out there have stable 1:1 settings for this set?

slacy,

Try turning off HDCP on Input Adjust. I was having the same problems until I turned it off.

NEC 50XR4 with DVDO iScan VP30 (HDMI to DVI) - 1365x768p @ 59.94 Hz

HShift=60
HSize=1365
HFront=51
HSync=50
HBack=60

VShift=12
VSize=768
VFront=4
VSync=4
VBack=12

Sync type: H+V+

As others have documented, the orbiter must be turned OFF and RGB Select set to "AUTO" for this setting to work. The odd thing was I could not switch directly from, say, 768p-60 or 1080i-60 straight to the "User" format into which this mode was programmed -- instead, I had to select another format such as 1440x1152 and *then* select "User", at which point the 50XR4 found a signal and switched to 1024x768 at location 24. I noticed that the sync type had become H-V-, changed it to the requisite H+V+ and *BAM* the magic 1365x768 at location 18 came up.

Quote, "I noticed that the sync type had become H-V-, changed it to the requisite H+V+ and *BAM* the magic 1365x768 at location 18 came up."

Are you referring to the plasma? I have the Mitsu version of yours and my frequency as reported by my plasma is Negative on both H&V. You have the ability to change this on the NEC? I do not believe I can. Pleae confirm, as this may explain a few of the issues I have always had with getting 1:1.

No, Gsheperdogs, I changed the sync type on the VP30; the NEC doesn't allow me to control sync type either.

One thing about this setting: once engaged, the only available screen size is "anamorphic" -- even 2.35:1 isn't available. Also, the number of adjustable options under the "Picture" menu is reduced, with the only available modes being "normal" and "default".

Interesting how different plasmas can be. Your NEC, MinkyMomo is one generation ahead of mine, but both are made by NEC. My settings are significantly different than yours, and I tried your settings, and they do not work.

Here are my updated settings:
H Shift 256
H size 1360 (can not get 1365 to work)
H front 64
H sync 112
H back 256

V shift 1
V size 768
V front 1
V sync 4
V back 20

I have to set the plasma to Wide 1 and it shows a negative sync on both H&V. The Iscan HD I am using does not have the ability to change the sync on the DVI output.

Any setting for an LG 52" DLP and HD+?

I'm a proud new owner of an NEC 50XR5. Here are timings and technique for 1:1 mapping. The timings I got from Mark's post in the Lumagen forum about the prior NEC model and they seem to work perfectly for the 50XR5.



VTOT 788 HTOT 1526
VACT 768 HACT 1365
VSYN 4 HSYN 50
VFRN 4 HFRN 51

V freq. 60.00 Hz


Make sure RGB select in setup menu is set to "auto"
Disable orbiting in PDP saver menu
Set image adjust values all to zero.
That's it. Double check signal info in the menu and it should read 1365 x 768 and memory 18.

V-line and H-line patterns via the Lumagen test patterns are perfect one-pixel rows and the overscan test pattern is a perfect fit.

The brightness/contrast is limited for PC input signals (including native). This can be remedied in the SM. PM me if you need help with this.

Hope this helps someone.

Quick question

Is there a mathematical equation to figure out what these numbers should be or do you just keep changing for best looking test patterns? The only numbers I know what to input are H-size 854 and V-size 480

Does anyone has the NR setting on DVDO iScan HD+for this plasma TV ?
Thanks.

This panel requires information about the 1024-by-512 resolution to be programed into it's internal memory! After I have this unit for four years, I finally realized that I have not been reading the manual correctly, although the native rate is 1024-by-1024, the manual never says that it will take a 1024-by-1024 input. In order to program the panel to accept a 1024-by-512 signal see the link below:

I hope someone can figure out how we can get to 1024-by-1024 with this panel because I can't :)

Has anybody been able to successfully setup this screen under Linux (I am using SuSE 10) using VGA connector?

Could you please list parameter values from xconfig file?

Many thanks in advance,

anyone have luck with a Fujitsu P50XTA51US using an iscan HD via the VGA input? Any feedback would be GREATLY appreciated.

Looks like I'll be buying a Panasonic TH-37PHD8UK which has a native resolution of 1024x720. Since it will be connected to a PC VGA port and used for movies, the PC's output resolution must be 16:9 square pixels or the image will be distorted as windows assumes square pixels.

The manual states that the panel will accept these 16:9 resolutions via VGA:

852x480
1066x600
1366x768

Since I want to use all the available resolution, the first two modes are ruled out, leaving 1366x768. Unfortunately this mode will result in both horizontal and vertical scaling by the builtin scaler. Hopefully this scaler is good.

The other possibility is to feed it 1280x720 and hope it can sync to the signal. Does anyone think this has a chance of working? It would, of course, be ideal!

the original resolution of this display is 1024x768.

You have to use 1366x768 because windows always assumes square pixels (which this particular display does not have).

The resolution is 1024x720 (here (http://catalog2.panasonic.com/webapp/wcs/stores/servlet/ModelDetail?storeId=11201&catalogId=13051&itemId=94539&catGroupId=14624&surfModel=TH-37PHD8UK&displayTab=F)), though it probably won't much affect whether or not it accepts 1280x720.

On the plasma you also need to change the size on the width of the image to +1 or +2. When this value is set to '0' there is a lot of noise in the image.

Josh can you please confirm if these setting work for the P50XTA51US? Have you been able to get 1:1 with this model?

Here is what I noticed when I try these settings:

1. with 0 overscan the picture is not centered. If I set the overscan to 3 then the right side of the picture touches to side but the left side does not.

2. A soon as I changet he size of the image to +1 or +2 on the Fujitsu the test paterns no longer work. Does this mean that at that point the internal processor isnt being bypassed?

Thanks a bunch

Hi all,

Does anyone has the timing settings for Sanyo Z3 projector? The native resolution of the screen is 1280x720.

I would highly appreciate your sharing and thank you.

Anyone managed to get 1:1 working on this display?

Best,
Carl

Carl,

I did succeed if I remember correctly, using an iScan HD+. I think it was very close to the VESA 1024x768p60 values. I didn't pay close attention because it was rather easy to obtain the native rate lock at 60Hz.

BTW,

I had a resounding failure at trying to get NR (* at any vertical refresh rate!!! *) on the NEC 42XR4 through HDMI inputs!!

I couldn't even get it to work at 60Hz (not to mention at any other rate!!).

Any ideas?

According to NEC, NR works over HDMI on the 42XR4 but only via DVI output from HTPC/scaler. This is according to emails from NEC tech support through their website, so you might try dropping them a note.

cpcat,

Of course, that's BS because the plasma can't tell where it's coming from (an HDMI or DVI source, if it's adequate DVI timing using RGB).

If you have a lead please let me know (if the lead is private, PM me). I've had no luck with trying to obtain NR timing.

I have a VESA timing database here somewhere, I'll try and see if I can find a combo that will work.

Did you try emailing NEC tech support through their website?

Ofer,

Try the attached. These timings came from NEC and are marked 1024 x 768D. I assume they marked this with a D to designate it is the digital timing. This goes back a while and comes from a master spreadsheet NEC let loose to several of us after requesting info on 1360 x 768 and 1365 x 768. Hope this works.

Update: those timings worked perfectly!

By any chance do you have similar ones for 50Hz, 75Hz or 100Hz?

Hi Ofer,

Glad that worked. I do not believe any other timings are supported. Here are the other relavent timings related to NEC's that were contained in the spreadsheet.

You might try tech support for other timings, they, meaning NEC, do not have a problem sharing this information like most other mfg's seem to.

A follow up to my earlier post, does anyone have the NR setting on DVDO iScan HD+for the Hitachi 55" PDP?

Would setting up the NR by trial and error cause any damage to the plasma TV?

Thank you.

can some kind soul share with ur timings for this very old Panny model ? it's a 852x480.

I used the default timings in VP30. At both 50hz and 60Hz I can achieve 1:1 but the vertical lines are flickering. (I had a HD+ before and I was able to get rock-solid vertical lines, but I lost my settings :( )

Thanks for your help.

Help! I have a Panasonic 42PWD7UY, and I can't even get close to native rate on it through the analog BNC input with a DVD VP30 and 1.07. I've tried the settings posted here for the HD models with no luck. The main problem I'm having is that I can't even get the screen shifted correctly so that the first VP30 test pattern has a 1-pixel border --- the screen will go blank before I get close. The default settings of the 852x480 mode will shift the image to the left.

I'm wondering if it's because I'm using bi-level sync instead of the separate H/V syncs. The TV's BNC inputs has only three signals, and I believe I have to use the PC VGA input to send it sync signals. Perhaps it will be easier to just get the DVI blade.

These are the "out the box" settings and they work perfectly.Using a VisionPro HDP here with a Panasonic 50PHD8 and when I change the different timings, the vertical refresh rate changes as well, so I can't understand how these values would work for 48Hz, 50Hz and 60Hz. I also would like to have timings for 72Hz.

these timings are in pixel quantums, so they change accordingly when vertical refresh rates are changed.

in any case, Panasonic doesn't do well with non-59.94hz frequencies.

these timings are in pixel quantums, so they change accordingly when vertical refresh rates are changed.This flew straight over my head. What do you mean "pixel quantums". In addition, stoomonster was implying that the values were valid for all three refresh rates, whereas this doesn't seem to be the case.in any case, Panasonic doesn't do well with non-59.94hz frequencies.I'm going in with RGVHV--->VGA. With analogue Panasonic accepts pretty much anything. I have it running at 71.92Hz for instance, with no problem.

I've been fooling with my VP30 to try to achieve native rate on my Panasonic TH-50PX20 plasma running a VGA cable to the front of the unit. I'm almost there but can't get the horizontal resolution at 1:1. The horizontal line test pattern displays as you'd expect but I get solid gray on the vertical line pattern. It's so solid and without moire or rainbows that I wonder if there is something strange about how the display updated adjacent lines. I've tried every setting I can think of and all sorts of format parameters and I just get solid gray. The only thing that changes it is if I change the refresh rate from 60 to 48, then I can start to see the vertical lines but they are still not very good quality: they flicker and blur together in sections. When I display an HD picture or the HDNet test pattern, it doesn't look like I'm down to half the horizontal resolution as the line pattern would imply. The horizontal LPI appears to be about the same as the vertical on the HDNet test pattern.

Anyone know what is going on?

No expert Mike but could it be cabling? A certain amount of blur or softness in analogue video signals can come down to the quality of the cable/connectors used, typically increases in freq/refresh make this worse as the bandwidth is raised.

Obviously don't go out and spend a fortune on a new cable but if you have others to hand might be worth a go (or try some of the free return if you see no difference places).

PS I'll ask again... sticky this thread?!?! (I'm forever loosing it when need it ;) ).

I don't think it's the cabling. This is brand new top of the line cable from Cables To Go. Since the horizontal lines work but the vertical doesn't, I'm thinking it's some setting or timing issue.

Mike

For the TH-50PX20 connected via RGBVH --> PC input, here's what I'm using. These settings work perfectly aside from the fact that I can't get the vertical lines test pattern to display anything other than gray. When displaying resolution test patterns, however, I don't see any issues and the display appears to be operating at 1:1 since I get good alternating lines on the horizontal lines test and the HDNet test patterns indicate about the same line resolution for both H and V.

Asked this question before but with no reply so ask it again:- Can anyone give me the timing information of my Sanyo Z1 projector which is 964x544 in order to get a 1:1 pixel mapping with my Focus CenterStage CS-1.

Can anyone give me the timeing(control) information of the Mitsubishi HC-3000 projector (1280x768) so that my frined can create a customise resolution with his CenterStage CS-1 video processor for a 1:1 pixel matching? Thanks. :)

Just as a general question, what is the best way to start on these settings? I'm working with a 32" lcd set that I'm pretty sure no one here is going to even dream connecting up to a vp. While it's native res is listed as 1366 x 768, over hdmi it only works reliable at tv settings - 480p, 720p, 1080i, and 1080p (!) And while I can adjust those settings within my VP50, after I exit hdmi input, when I come back, the display no longer synchs, and I have to go back to plain vanilla 720p.

And no, I don't even know if it accepts native rate via hdmi. It does over rgb, but that cable is already going to my crt pj, and I'm not going to mess with connections there.

Thanks - and btw - now that I'm trying to do it, I realize what this thread is for. Just between us, what a pita. CRTs are MUCH friendlier. :)

You could try starting with the settings that work via VGA, I've got a 32" LCD that works okay for both, at least at 60Hz. But it only gets 1:1 at 1360x768 (with borders).

Maybe you have the same problem as reported here (http://www.avsforum.com/avs-vb/showthread.php?p=7964518&&#post7964518)? If so: this was later confirmed to be a bug in the VP30 by Josh and promised to be solved in the next firmware release (not released yet).

I'll try - but I know I'll have to do something more - at least for the hdmi. When I try that res over hdmi, I have a picture for half a second or so, and then its gone. And it won't come back. My set also has the bad habit, in that once it looses synch or whatever, it doesn't like to come back, except all the way to a standard setting. Makes things a bit slower. :( Would be a lot easier if I could increment/decrement, and then once I lost the pic, go back one. But that usually doesn't work.

Oh well - was just having a bit of fun anyway - not really cost effective to be running a VP50 into a 600 dollar panel. ;)

42PHD8 over RGBHV (almost trivial) into BNC board.

From iScan vp30 or vp50: XGA Format gives NR pixel matching then just use horiz/vert shift to nudge a couple of pixels to position the frame correctly.

Choddo. Sorry for the trivial question but does RGBHV involve 5 cables from the VPxx to the panasonic? I thought there were only 3 BNC inputs to the panasonic. Does the RGBHV include the L/R Audio inputs? Sorry again for the stupid question.

I was told that the Sony V40XBR1 LCD panel can't do NR pixel matching at all. I would really appreciate it if any helpful guy from this forum could confirm this is true. Thank you.

Hi, it's 5BNCs for the picture, it's a 2slot board that includes composite, s-video, audio inputs (which I don't use) and 5 BNCs, the TY42-TM6Y, there's also a smaller component video over BNC board that only has 3 terminals (TY42-TM6A) which may be the one you're thinking of?

That was what I was thinking. Didn't realize there was a separate board. Thanks.

Vince I have the KDL-V40XBR1 and no it does not do 1:1 pixel matching over HDMI. But it DOES do 1:1 (ok 1365x768) over the VGA port. That's how I have mine setup with my VP50. I'm really enjoying this setup. Of course alot of the picture controls aren't available (but you have them with a quality VP anyways) on the VGA port and you'll be "stuck" using component for sources that have HDCP but IMO it's not a bad tradeoff.

FYI: The newer XBR2 & 3's will do full 1920x1080 1:1 over HDMI. The 46" will be my next TV--hopefully in the next 6 months or so.

Hope that helps.

Talman, thanks and really appreciate your reassuring response.

I have tried inputing the vga port out from the VP30's analogue output via RGBHV BNC output. No success, image looked off-centered and did not filled up the width of the panel
for 1280x768 format. 1365x768 was not able to get display of test pattern at all.

If you are agreeable, can you post all the settings for the 1365x768 format which worked on your panel including inputs and suggestions you think I may need.

Appreciate your kind contribution.

Choddo. I'm thinking of just going into the 3 BNC component input standard on the Panny (and the corresponding BNC component output of the 50). Any reason you think this might not get 1:1? Thanks.

If you're having trouble getting it to work, buy a DVI card for your display. I tried getting 1:1 mapping over component on a 7 series 42" and never quite succeeded. Switching to HDMI solved the problem.

Hi Steve,

thank you for the answer.

I have the DVI-card in my plasma. But the resolution here is 1024x768@60Hz - and I need @50Hz.
I read that at VGA a perfect pixel-mapping is enable.
You tried at a component-card? This is not VGA.

It's been two years since I had that the 42" PHD7, but I'm almost positive I tried both component and VGA. A VGA cable can send either analog component (YPbPr) or analog RGB, so the results should be the same in any case.

I don't understand what you're saying about the DVI card. Are you saying it won't support 50Hz? I would think it would.

Oh, and I'm almost positive I tried both RGB and component (YPbPr) colorspaces with the VGA cable, as the iScan (I have the HD+) supports selecting.

The dvi-card only support 576p@50Hz. All other resolutions @60Hz.

At times they'll support resolutions that aren't listed; I say that in the unlikely case that you didn't try it.

I don't mean listed in the manual. Many user say, that the DVI-card support only 576p@50Hz, all other resolution @60Hz, with having judder!
See post #9 in this thread:

DVI is notoriously difficult on Panny plasmas, with the board supporting:
480p, 720p and 1080i @ 60Hz
576p @ 50Hz

Hmm, you tried it and had the result: 1024x768@50Hz connected with the DVI-card? Maybe it's my last hope ...

My situation is different from yours, so I don't know if it would work or not. But if you've not tried it, give it a shot.

I have a 7 series plasma and I'm using DVI from the iScan HD+ to an HDMI card, not a DVI card. I'm also running at 60Hz. So I have no experience with your exact configuration. However, the specs for the HDMI card theoretically didn't include native rate and it works fine. I also had people regularly telling me it wouldn't work, so reports aren't always correct.

Turns out they broke it in the 8 and 9 series versions of the same card though. So you can never tell what may work. Personally I'm not too optimistic given what you said, but it never hurts to try.

Hi Offer, quick question for you -

if a panel is 1080p and accepts 1080p signals, would that mean for sure you are seeing 1:1, or is it likely the panel could be doing some rescaling/processing of its own?

ie: Pioneer's 5000EX/ELite 1080p has a 1:1 mode..... outside that mode, even sending 1080p, can you see a difference in PQ?

thanks,

Hi Steve,

I tried it. I connected the VP50 with DVI-card of the Plasma. But the result is the same as with the VGA-connection: On the test pattern 'vertical lines' and 'horizontal lines' I get no black and white lines, they are grey and light grey. No pixel-mapping.

Not all resolutions work, but 1024x768 works. But I had a blinking white line at the bottom of the display.

So I must wait and hope that someone here post the perfect settings for my configuration.

Thank you for your help!

Ah, so the DVI actually does support that resolution. Excellent. (Note that supporting the resolution and getting pixel perfect mapping are two different things.)

You may be waiting a while for someone to show up with your exact config. Have you used to the test patterns to be sure there isn't overscan on the display, changed front and back porch in the VP50, etc.?

big_marcello,

the answer is definitely yes. Put up a high frequency source and you'll see bands due to double scaling.

many 1080p displays and projectors have 2 modes: native rate (they call it by different names) and "regular" (usually meaning 5% overscan is turned on).

I just took delivery of an NEC 50XR6 plasma panel. I am using this with a VP50 and am having some difficulties with native rate. Here are my current output setup:

Format: 1365x768
Sync Type: H-/V-
Color Space: RGB
Output Level: PC

When I display the test patterns here is what I see:

Frame Geometry: The right side of the display, the border is not white but more of a magenta color.
Checkerboard: Seems okay
Vertical Lines: The display is completely green.
Horizontal Lines: Seems okay.

When I check the display info on the TV, it shows the following:

H. Frequency: 47.2 KHZ
V. Frequency: 60.0 HZ
H. Polarity: Negative
V. Polarity: Negative
Memory: 18
Resolution: 1365x768

So, how do I get the geometry and 1:1 pixel map test patterns to display correctly?

Thanks for any and all help.

mcnisiv,

Try sync type H+/V+.

I tried that and still no good. Thanks for the reply though.

I have a fujitsu P50xha58eb and a DVDO v50Pro, I input 576i/50hz RGB, what would be the native timings I would need to set on the DVDO to get 1:1 mapping. The native resolution of the fujitsu is 1366 *768.

Help much appreciated

Have you tried the default timings for 1366x768 in the VP's Output > Format menu?

If those don't work (use the test patterns to confirm), you should look in your display's manual for the required Horizontal/Vertical frequencies and Pixel Clock. If you know these, you can use a calculator like this one (http://www.tkk.fi/Misc/Electronics/faq/vga2rgb/calc.html) to help you figure out the other timing values.

It may take some trial and error, but you should be able to work it out eventually. If the default timings for 1366x768 are close, you can use that as your starting point and adjust the values from there.

Thanks for your reply, I have tried the native settings and get a picture but offset to the left by 10cm. despite altering the horizontal front and back porch settings ( and the screens own offset ) I cannot centre the picture.

I am looking for a solution, given that I have an external scaler I want to bypass the Fujitsu's own scaling process and force it to take its native resolution from the DVDO V50pro, otherwise I am defeating the object of havinga scaler.

I tried the calculator, but I am not sure I have the correct frequency ( 85.5 mhz, and the manual for the TV does not give that information.)

Any other ideas greatfully received.

According to the manual (http://www.hdtvsolutions.com/pdf/P42_50XHA58UBb_Manual.pdf) that I'm looking at, you actually need to set the resolution to 1360 x 768 (with a horizontal frequency of 47.71 Hz and a vertical frequency of 60.01 Hz). There are two presets for this resolution in the Output > Format menu. Have you tried them?

If you look in the Features > Adjustment menu of your display, it looks like there is some information on the Dot Clock (Pixel clock) too.

If all else fails, you can always try DVDO support. Aaron might know the timings.
