Custom Resolution Guide for 1080i HDTV-HTPC-POWERSTRIP-RADEON - Page 53

Cheers HeadRusch,

I have tried using vga to vga, and dvi to hdmi with the same results. LIke I say, The hitachi "displays" a reported desktop res of 1920x1080...but at 60Hz. (I know really its a scaled res to the native 1280x720 panel).

However, here is the problem....my previous projector, a sanyo z2 model (1280x720 HD) gave me a 1920x1080i (interlaced) flickering desktop at 30Hz...but it deinterlaced 1080i (interlaced) HD clips and movies stored on my hard drive very well 100% of the time. This is using exactly the same PC and drivers as with the Hitachi now...in fact I still have the sanyo z2..it still works perfectly solving this issue.

I always found the onboard deinterlacing of the projectror to be "cleaner" than the software solution of using Theatertek or those with VLC or MPC. In addition it allows the PC to run the HD clips with more "headroom" as the deinterlacing is off loaded to the projector.

This problem is driving me nuts..especially as i just laid down big bucks on the Hitachi.

Any mores uggestions apart rom the ATI dongle?

Thanks guys, much appreciated,

Cheers,

Sean.

Unsure, I'm afraid. Perhaps the Hitachi just did away with modes it felt it would never encounter. I know HDMI is very strict about what it will and will not pass. VGA I'm surprised ti gave you grief...

Then again do you know if the Deinterlacing of the Hitachi is as good as it was on your Z2? If you did feed it an interlaced signal and let the Hitachi deinterlace your source (and then scale it down to 720p), have you any idea if it would look as good as on your old Z2?

If you feed your Hitachi a 1080p desktop (60Hz) and feed it a 1080i clip..which of course is displayed at 720p on the PJ, is it a mess of combing artifacts and such...? Is that what you're trying to solev without having to resort to software solutions?

Thanks,

Yes thats exactly what I'm trying to solve.

No matter what I try in the ATI ccc or powerstrip, it seems to give an "attempted" 1080p desktop instead of 1080i 30Hz, so 1080i clips always play completely interlaced.

I've spoken to Hitachi, UK about it, they said they would get a tech guy to email me back...that was about a week ago!!

Apparently, according to reviews of this tx200 projector (hdpj52 to the guys over in the US) it is pretty good at 1080i. No one else has ever mentioned this situation, which leads me to believe it cant be a generic "fault" with this model, as I'm sure many people must play 1080i HD stuff from their PC's.

It deinterlaces dvds from a non progressive scan player at standard def fine.

Do you think it could be a case of "critical timings" with this pj - ati combo, or should I try the "dongle" thing?

If I have to resort to software deinterlacing (any suggestions which one is best?) In my limited experience, theatertek sems to be the best.

Cheers,

Sean.

First off, this is a great thread, I've reading it over for a few weeks while working with my HTPC. Unfortunately nothing has been able to solve my problem yet.

Here's my equipment:
Windows XP SP2
Radeon 9600 LE
ATI DVI - Component Video Adaptor
Panasonic Tau CT-26WX15N widescreen CRT HDTV

So far I have been able to make only two resolutions work relatively well using powerstrip: 1776x1000 30 hz (works perfectly) and 856x480 60 hz (edges slightly cut off on all sides, i.e. the bottom half of the taskbar is not viewable, the top and left sides of the "My Computer" icon is cut off at the top left of the screen). Unfortunately 1776x1000 is too large to read almost anything, and 856x480 doesn't give enough room for many things to be displayed.

Does someone have an idea what settings I should focus on to make a resolution like 960x540 or something like that work? For some reason 960x540 with a 33.75 scan rate just goes completely black on my tv. Please let me know if anyone has any tips, thanks!

This thread looks like it will help, but it's a little too big and detailed for me to search while at work. I'll be investigating over the next few nights. In the meantime, I'll post my issue and maybe someone knows a quick answer!

TV: I just bought a samsung 42" DLP tv (HL-R4266W). It has component, s-vid, composite, and HDMI/DVI inputs. I believe it is 1280x720p native, but it isn't listed in the manual.

PC: Dell 4600C Media Center, using ATI All-in-wonder 9000 low profile (which is a radeon). It has no digital video signals out, only VGA, S-video, and composite. So my best choice is S-video. I've been using s-video for a few years to my CRT 36", and used 800x600 resolution, and was pretty happy with it for TV and video viewing, but wasn't too usable as a pc for web browsing or other programs.

What I want to do is just to take advantage of the wide aspect ratio of my new TV. Media center can do 16:9 aspect, and windows can easily do it. What I'm having a problem with is getting a resolution larger than 1024x768 out the TV display WITHOUT it doing any virtual desktop scrolling. My ATI will easily let me pick larger resolutions, including a 1366x768 built into the control panel, but I can't use the scrolling. I end up with vertical bars on each side, with the center scrolling. Ridiculous!

Problems: The ATI display drivers cannot be updated on these particular media centers, else the WDM encoders get hosed. Also, I can't install the catalyst control center because it isn't compatible with this older version of display drivers. So I don't have all the ATI goodness of their validated timings and resolutions available to me.

So I spent a few hours last night trying to get some wide aspect ratios out to my TV using powerstrip. I actually used a pretty sweet setup by controlling the display using a VNC session on my laptop so that when the display on the TV goes corrupt, I can still use the mouse/keyboard and see what it was supposed to look like, and undo changes. (The VNC session actually resizes dynamically, which was a welcome surprise). The first time I tried a 1280x720 res, the driver actually accepted it. The problem was that it still used virtual desktop scrolling and had sidebars. So I noticed that even when you pick the resolution, there is still the "active" pixels that will show up on the screen at any given time. So of course I tried bumping these up higher, but I just get scrambled pictures whenever I go above 1024 or 768 in the respective direction. I tried a few sets of timings I found by web searching but haven't had any luck yet.

But I'm not giving up! Unless of course some one can tell me that s-video itself is limited to only 1024x768 in and of itself (which I thought that it really only outputs 480i so I would think that isn't the case). I'm not actually shooting for hi-def from my PC to my HDTV, I just want the wide aspect and cleaner picture than I used to have on my CRT. I use my cable box for all my HD content.

Any help appreciated!!

HI Guys relative newbie here,

Just purchased a Viewsonic N4060W LCD TV and was trying to set it up for 1:1 pixel mapping which occording to the manual is 1360 x 768 @ 60Hz.

All seems to go well until i switch to the resolution and get the image to display, but for some reason the TV reports 1080i and the picture is horrible.

As i nderstand it the monitor will only display 1360 x 768 (Native LCD Panel size) non interlaced. I'm running it via a HDMI - DVI cable....

Tried to untick the interlaced tick in powerstip and create a custom res but the screen loose sync.

Any help would be most appiceated in solving this issue.... i must be missing something !

Hade a simular problem when i was setting up my Sony HS-10 projector, it had a wacky resolution of 56 Hz, if you didn't get it right it just didn't work.


Thanks in advance....

Hi,

I don't know if a straight digital (DVD/HDMi) will work directly between your vid card and display and may be a waste anyway.

You need(depending on vid card) a vga or dvi to component transcoder and use the hard work that KARNIS has done for us.

READ ALL OF THIS BEFORE PROCEEDING TO SEND REZEZ TO YOUR HD DISPLAY.

hi petermwilson,

What i didnt mention is that i have been able to output 1280 x 768 with no issues.
What i guess i'm screaching for is that elusive 1:1 mapping, which only seems to be aviabale through the PC (VGA) port on the TV. When i sent an email to Viewsonic this is what i got back.

-------------------------------------------
Dear Customer,
Thank You for contacting ViewSonic Support regarding your N4060w LCD television. This is an issue because the HDMI port does not support DVI cables completely; The connection has to be established using a HDMI cable. Although, you got a clear picture when connecting using DVI cable, we do not support DVI to HDMI. Try connecting using a HDMI cable and then try to change your PC setting to the recommended resolution. If you have any other questions, please feel free to contact us at 1-800-688-6688; We are open 24 hours a day, 7 days a week.

thanks anways, i'll keep on trucking and see where it leads me.

@ daemonic ...post # 1565 -- And/or anyone/everyone else.

Here is a quote from the first post talking about avoiding the "Virtual Desktop"(VD):

~
"It is also important to note that the monitor you specify in Windows must be capable of resolving the resolutions you present to the display driver in progressive scan mode. I have used the Sony GDM-W900 monitor drivers because it has a max resolution of >1920x1200p as listed in Powerstrip 3 monitor profiles. Make sure to "disable plug & play monitors". Selecting a high-resolution monitor will also help avoid "virtual desktop", or a side scrolling desktop. Powerstrip will allow you to create your own custom monitor driver. I made a driver for my Mits HDTV based on the Sony specs and is attached later in this thread. If you are having trouble activating high resolutions, try double-clicking on the monitor icon next to the resolution slider in the Display profiles screen, and Powerstrip will attempt to uncap rez restrictions. When using the ATI HDTV adapter, it takes priority over any monitor driver you have selected."
~

But if you problem is like mine(see below) you might be outputing 4:3 vs 16:9. And maybe 4:3 does have a limit of 1024x768 without going into "VD" mode.

Well, hope this helps someone and that I was just not filling up the thread for no reason...I'll likely not be back anytime soon. Good Luck and thanks to everyone for the AVS Fourm inputs.

Sup all, I hope everyone is doing fine.

I have an Xbox running XBMC into a 34XBR960 It seems to be running at 720x480 in NTSC 16:9, from an 'advanced video pack' s-video connection. So the s-video on this XBR does 16:9 on s-video...

I'm wanting to get my ATI 9600se to put out 16:9 over the 'TV output' s-video but it seems to only wanna do 4:3. I've played with the 'ATI Catalyst' and the newest 'Powerstrip' but It just seems like it does not do 19:6 out of the 'tv out s-video connection' on this ATI 9600se.

I'd love to know if the ATI 9600se can do 16:9 out of the S-Video connection.

nevermind

Hi, there seems to be a lot of very smart and experienced people on this forum. Here is my problem. Hopefully, someone can give me advice on this.

I have an ATI Radeon 9800 based PC with the max resolution of 1920x1200. It has 1 DVI and 1 VGA output. The DVI output is connected to a 24in widescreen monitor at the max resolution and has been working perfectly. I would like to keep it as is.
However, I just got a Sony VPL-HS51 projector. The projector has many inputs including HDMI and VGA. Based on its manual, it supports the max setting of 720/50p via HDMI and 1280x720 via VGA.

What I need an advice on is about the best way to connect my PC to the projector (for the best picture quality). My PC is my only enterntaiment center - I currently watch DVD's on the DVD-ROM drive. Hence, I want the best picture possible. Also, I am now looking to buy a HDTV tuner card to watch digital over-the-air programming on my PC.

I currently have four reservations: (1) if I were to use DVI-HDMI connection, the displayed PC desktop would be of very low resolution on the projected screen (although movies might be fine), Plus I would probably have to purchase a new video card with dual DVI outputs (2) if I were to use the VGA-VGA connection, I would get an analog and not digital picture of 480p when watching DVD's and 1080i when I buy the tuner card, (3) I would strongly like to keep the current DVI-digital widescreen display connection in place, (4) The projector is about 25ft away from the PC. So, I will need a 30ft cable to connect the two.

What is the most optimal connection for me to get the best possible quality out of my PC?
Should I consider buying a new dual DVI video card? Is the price tag of ~$200 for 30ft DVI cable really worth it?

Many thanks!

Hi there,

I'm having big problems with my HTPC setup.

My TV is a fairly old 32" Panasonic LCD - TX-32LXD1. It only has Scart and component inputs. I'm plugging in my HTPC via a 9800pro gfx card with the ATI DVI -> component adapter (the one with the switches for 720p etc). I have the lastest version of CCC and powerstrip installed.

The default resoltion when I boot up is 720 x 400. This is fine for watching DivX and using WMC, but no good for anything else (games, internet etc).

If I try to increase the resolution using control panel, CCC or powerstrip, I get the same result - the picture goes (like an old VHS player with really bad tracking).

The TV has 1280 x 768 pixels and has a 15:9 aspect ratio (some weird Panasonic thing), so I think it should be able to accept a higher resolution. It appears that the ATI component adapter only outputs to certain resolutions, 480i, 720p and 1080i. I figure 720p is probably the best fit I can get (1280 x 720, so perfect horizontal fit and then some vertical scaling). Anyhow, I can't get any permutation of 1280x768 or 1280x720 etc to work. In fact I can't get anything that isn't 720x400 to work.

Oh yeah, one other thing I discovered yesterday - if I set the "desktop area" in CCC to 1280x768 or 1280x720, then the picture doesn't break up, instead it zooms in, so I can only see about a quarter of the desktop.

This is driving me nuts as I'm sure the potential is there for this setup to work, but I just can't figure out for the life of me how to get those higher resolutions without losing the picture.

Sorry for the lengthy post, I'm just getting desparate and want to make sure that all of the details of the problema are covered.

If anyone can help me out with this I'll be eternally grateful.

Cheers,

Fred

Hi,
Please go to seach at top of page.
in search window type KARNIS. When you find custom resolutions print and read his entire post on the matter.

Or go to Digital Connection (you may have to register) I think there's an updated verion of Wayne Harellson (KARNIS) in the htpc support section

How do I adjust the resolution for BATTLEFIELD 2 PC game? The game is a small rectangle inside a black box of unused space.

I have the same Mitsu ws55819 used for this thread, RADEON 9800 Pro, 856x480p timings and ATI dongle.

I have noticed that some programs have the bottom section of the page cut off...or ideally I have to scroll down. For this game it shrinks the display so I can see everything but it's hard to read the fonts and wastes a lot of screen.

Hello all,

I was wondering if anyone could give me some hints on getting powerstrip to work with my HDTV. So far I have been unable to find a setting in powerstip that my TV likes. I have an ATI Xpress 200 video card built into my HTPC motherboard, and I am connecting to my HDTV via a DVI to HDMI cable. In Catalyst, I can get 1920x1080i 30Hz to work but there is significant overscan. Any adjustments in Powerstrip makes my TV drop out of lock. I've been doing a lot of reading about powerstrip, but I cannot seem to get my TV to work with any custom settings. None of the settings from the post on ATI timings seem to work for me. Any thoughts?

You should change the Command line to the resolution that your HDTV is running at. Read the section titled "Command Line" in this excellent tweak guide for details on changing it:

http://www.tweakguides.com/BF2_7.html

What is your HDTV model ? I assume you've looked at the PowerStrip forum on HDTV timings ? http://www.entechtaiwan.net/forums/v...a133837980b3d8

Chazim, I realize it's a while ago since you posted this, but if you still have problems getting a custom 1080i resolution that your TV will sync to thru HDMI, you may want to take a look at this thread:

Guide to 1080i DVI-HDMI on Radeon

Catalyst 5.5 and newer simply won't do interlaced signals properly thru DVI-HDMI on some ATI Radeon cards -- even with PowerStrip. I believe that's why so many people just recommend using the ATI Component dongle instead.

After months of experimenting I found a procedure to trick the ATI driver which at least works on my Radeon 9550 and with my Toshiba 56HM195 DLP. Hitting the right timings in PowerStrip is NOT enough, you have to add the custom resolution as progressive before trying to switch to it, then update it to interlaced timings afterwards.

Check it out and see if it works for you. I'd appreciate a brief yes/no posted in that thread on whether it worked for you or not.

Great post, big help.

I can't seem to find anyone successfully using this set with a Radeon/Powerstrip. I can't find any timings for it either and there aren't any in the Entech forums(there are timings for the 30" wide screen though). Since I am trying to use the adapter do I really need timings for the tv or just the adapter? Oh, I am using a Radeon 9800 pro.


Also, not to seem ungrateful but the guide doesn't say anything about the newer CCC drivers. I am using Cat 6.5 at the moment. I guess I'll go back and re-read the long thread for my tv. Thanks in advance for any info.

I read many references to the "ATI DVI - Component Video Adaptor" or dongle. Is this mainly for those that do not have an DVI input on their TV?

I have an ATI AIW 9800 pro. My HDTV has DVI, VGA, and Component inputs. Do I need the adapter to hook up to my TV.

1080i on infocus sp4800 with PowerStrip anyone?

Hi,
I've tried connecting my Saphire x1900gt video card component out to my hdtv ready tv from toshiba (CRT 29UC7 -4:3).

Using the newest catalist, i keep getting a very small image display in the center of the screen with very wide margines in the top and bottom.

Is would be very thanksfull for any tip you can give,
Thanks a lot!

Always select Lock All Geometry before changing the physical resolution. You should find it easy from there.

I am new to all of this and I am trying. Here is my set up:

My TV:
Mitsubishi WS73909
Hi Def is run through the component video input.

My Video Card:
ATI Radeon X1600 PRO:
The DVI out on the card goes to an LCD monitor.
This connection works just fine.

The S-Video output on the card goes to the component video converter that came with the card.
I have been able to set the resolution to 1920x1080 but I have a lot of overscan it seems. The picture is also horribly out of whack in regards to the colors and it seems kind of fuzzy.

My Goal:
I would like to play all video formats and picture formats (maybe occasional web surfing) on the Mitsubishi.

Is Powerstrip something I need to be examining more closely and run it with the ATI Catalyst suite? Which direction should I be looking in?

Thanks for any help.
Elliott

Hi,

Go backwords from your post to links that will help.

Peter M.

Your WS-73909 is (IIRC) pretty much identical to my WS-65909 other than having a larger screen and 9" instead of 7" guns. But the video input and processing capabilties are otherwise pretty much identical. This means that the TV will only accept sources that output 480i, 480p, and 1080i. It will not accept 720p, 1080p, other computer resolutions, etc. To deal with overscan, you can use Powerstrip to setup resolutions within a 1080i timing so you can see your entire desktop, but the best you'll end up with is something less than a 720x480 (basically 720x480 minus enough to deal with the overscan) Windows desktop to use for things like browsing. In my experience, it's fine for occassional web browsing but would be very frustrating to use on a regular basis because there just isn't enough resolution to work with. For watching DVD's, you can go with a higher resolution, effectively interlaced (as in lots of flicker if you're looking at the Windows desktop), mode that will work great - IIRC, I'm using the 1440x480 mode for DVD playback which is a good choice because it's exactly double 720 which makes for nice scaling.

As has already been said, go back to the first post for some excellent information, do a bit more reading through the thread, and then come back with any questions you still might have.

Ok, I have been reading the posts but I am not quite sure what the exact definition of "dongle" is. Is it the VGA to Component adapter (which has dip switch settings), is it the DVI to Compnent adapter (which has dip switch settings), or is it the S-Video to component adapter (which does not have dip switch settings) ? I am using the S-Video to component adapter. The reason I ask for the precise definition is because of the beginning post which mentions separate settings for use of a dongle.

Thanks,
Elliott
