I've asked this before in the video processor forum but with no luck, so, I'll try again here.


Any help would be really really appreciated, I don't have much time to mess around myself, I'll get killed if the missus would have to miss her programs cause I'm still messing trying to get 1:1 mapping working..


So here goes, again..


I've got the Panasonic 50" 6 series monitor and one of the new Lumagen ProHDP's


Looking to get 1366 x 768, 1:1 mapping via DVI, I realise this will have to be at 60/59.94Hz due to the limitations of the Panasonics DVI interface.


I need:

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


Obviously it would be best to have the settings from someone who is using one of the new Lumagen scalers but anyones settings would do such as a HTPC, Crystalio, iScan HD etc.. As I'm sure the guys at Lumagen would be able to tell me how to convert your settings to those of the Lumagens.



If possible I'd also like to try out 1:1 mapping via the analogue RGBHV connnection to compare as with the analogue connection I can use 50/75Hz which would mean no nasty 50-60Hz induced judder. So can anyone also provide the 1:1 mapping settings for 50Hz analogue connection?



Cheers

No one out there got any info at all??


Has anyone seen this info posted previously, if so could you point me in the right direction?


Cheers

Here's a photo of the signal chart from the DVI blade manual.

Does this help? I don't see any V Front, V Total or H Front, H Total though.


What do you mean exactly by the "service menu settings for H Pos/V Pos/H Size/V Size"? These variables are set via the remote control when you bring up the on-screen menu.

Here's a post that should help get you close. It's for 1360x768 on a P50. Using the timings above and the other settings in the linked post with the appropriate adjustments for 1366, you should get close. Then it's just a matter of tweaking, trial and error. You'll also have to convert the power strip settings to your Lumagen paramters - shouldn't be hard. Also, in the linked thread there may be settings in a slightly different format (for Bravo D1) that may map easier.

Cheers but I've already seen the manual for the possible inputs of the DVI blade, hence why I know it has to be at 60Hz, but what I'm after is specific timing details to get it to snap in on the display i.e the sort of thing you would get from a powerstrip custom resolution when using a PC...


The service menu settings I refer to are in reference to the values you can set for the horizontal and vertical positioning of the image within the serivce menu, not the normal picture position menu where you only have a sliding scale to move up and down.

Hi Larry


Thanks for the link I'll try those numbers out, though I think I've already tried the settings listed by Dale (DVDO) on the iScanHD thread refering to the P50 as I was told they would work on the Panny (being the same galss) but they didn't so I don't know if these will be any different, I'm thinking same glass but its the different electronics that need different values.


So anyone out there actually using a Panasonic 50??


Cheers


Ryan

That's why I said "close". If you tried the settings for the Iscan exacty as stated, they won't work if the Panny actually does 1366x768. You'll need to account for the extra 6 lines in "h size" and "h total" (add 6 too each). "h synch", "h pos", and "h front" would need to have the 6 lines accounted for also. "h total" - "h size" = "h sync" + "h pos" + "h front". If you already know this, ok. If not, it will help. I'm assuming "pos" and "front" are the same as "back porch" and "front porch". If not, Lumagen should be able to help with the conversions. Also, use the horizontal timing above (48.36), not the Iscan or "tmmort P50" timing. Also, 60.0Hz vertical timing may not work, but 59.9 will or 60.0x will.


good luck

Here are the powerstrip settings from my .inf file. It was created to go with the Panasonic DVI TY-42TM6D DVI board so I don't know if it will be any help to you though:


[Strings]

MFG="Panasonic"

MODEL="TY-42TM6D"

MAXRES="1366,768"

MODE="MODES\\1366,768"

RANGE="30.0-73.0,50.0-61.0,+,+"

Edaly,

When you are using Powerstrip with these settings, can't you "dump" the actual timing settings it is currently using? (I've seen screenshots of the display and somehow tmmort retrieved them as he posted in the link above). Have you verified you are getting 1:1 mapping? One way I think people do it is by displaying a 1366x768 .bmp image file that they have created.

Ryan,


The Panny DVI board has higher than normal horizontal scan

frequency (48.4kHz vs 47.9kHz) for the1366x768 res. I

found this out by playing with settings on my scaler (It is

a HD Leeza) and it is very very finicky. I get no picture at 47.9

but get one at 48.4. Analog RGBHV works with either.


I suggest adding more pixels to the front and back porches to

up the pixel rate a little.


I have been meaning to fix this. In order to get the exact

timings I need to get a Matrox Parhelia or the new P7xx cards

to drive it at 1366 .My current Radeon can only do 1360 or 1368.

Heya.. I finally figured out how to pull the timings out of Powerstrip. Not really very difficult, but I discovered I wasn't actually running the program itself, only the "quick setup" before it shut itself down (trial expired).


Here's the info. I hope this is what you were after.

Thanks. Hopefully rscott can do something with them and any folks who are curious in the future.

Edaly,


I'm going to copy these (with credit to you) over to the native rate thread in the video processors forum.


Thanks!!

 

[rscott4563]

Ooooo.....


Can't wait to give these a try, I'll get back to you with my findings.


Cheers

I've got the place to myself for a few hours this afternoon so I'm going to have a go at getting my Lumagen ProHDP to give me 1:1 with my Panny 50"


One thing I was wondering, Edaly do you have the Panasonic serivce menu values for position and size??


Cheers


Ryan

 

[rscott4563]

Result!!!!


Total sucess, it took me literally 10 mins and by using the exact values from Edaly's powerstrip timings.


It was very easy, I entered the values, then displayed the Lumagens built in crosshatch test screen. The crosshatching appeared dull, but then I reset the size/pos settings on the Lumagen back to default and then went in to the Panasonics service menu and started adjusting the vertical and horizontal position and size.


Very easy to do, when increasing the size its added to the left and bottom only, so all I needed to do was first adjust both the vertical and horizontal position to get the active area of the screen right up to the edge of the left and top of the screen.


Then all I needed to do was to start increasing the vertical and horizontal size until the image snaps in. This is very obvious to see when it happens, the crosshatching suddenly becomes very fine and sharp and the brightness increases a lot.


As soon as Lumagen bring in test patterns for 1:1 testing I'll be able to definitively confirm that I have 1:1, but as far as I'm concerned I've got it....


Thanks all for your help.
