I recently purchased a Sony LCD RPTV (50A10) and I think I have near perfect timings set up through my 6600GT using the VGA PC input. I think these settings will work on both the 50A10 and the 42A10 with most video cards. There have been a couple people that have had problems, but I suspect that there might have been problems with Powerstrip not applying the resolution properly.

I've posted my results on the A10 thread in the RPTV section, but I've been getting lots of questions. I'd like to set up a "Tutorial" for setting up this TV (and maybe help others setting up other TV's).

This only works when using the VGA PC input on the TV. When using the HDMI input, I cannot yield satisfactory results (see below). If you are able to yield 1:1 pixel mapping with HDMI, please reply to the post with your timings and settings!

First, you'll need to have powerstrip installed. If you aren't familiar with Powerstrip check out Karnis's custom resolution guide in the HTPC section, it's stickied on top.

Now, FYI, for those who don't know what 1:1 pixel mapping means:
It really has little to do with how much of the screen the picture fills. It has everything to do with one single pixel of the computer output matching exactly with a single pixel on the display device. Even though the sony LCD's have a total 1280x720 resolution, some of the pixels are "hidden" outside the visible screen area. Because of this, a special screen resolution must be created to fit the screen with little/no overscan.

This is what the screen should look like with 1:1 pixel mapping:

Notice how the pixels in the text and the mouse match exactly the pixels on the display.

And this is what it looks like when I either don't have 1:1 pixel mapping and/or when I am using HDMI:

Notice how the pixels are blurred. What should be one pixel is blurred across a few pixels.
______
Edit:
JMV was nice enough to share a bitmap he made to verify 1:1 pixel mapping, and he's given me permission to share with everyone. You can download it here:
http://i54.photobucket.com/albums/g9.../720P_test.jpg
Just set it as your background image, centered not stretched.
The left section has individual alternating black/white pixels and the right region is divided with half 1 pixel wide vertical lines and the other half 1 pixel tall horizontal lines.
______

I'm going to try to go through this step by step. Please let me know if you have any corrections/additions. Please don't PM me with questions, but rather post here in this thread. It helps everyone solve their problems as well.

Well...Here we go!...

First, you'll need to have powerstrip installed. If you don't have it, you can get it here:
http://www.entechtaiwan.com/util/ps.shtm
If you aren't familiar with Powerstrip check out Karnis's custom resolution guide in the HTPC section, it's stickied on top. That's a great source for info about Powerstrip.

Now, copy the ENTIRE section between the lines (__________) to the clipboard:

________________________________________

PowerStrip timing parameters:
1224x688=1224,104,128,208,688,45,5,58,79393,274

Generic timing details for 1224x688:
HFP=104 HSW=128 HBP=208 kHz=48 VFP=45 VSW=5 VBP=58 Hz=60

VESA detailed timing:
PClk=79.39 H.Active=1224 H.Blank=440 H.Offset=88 HSW=128 V.Active=688 V.Blank=108 V.Offset=45 VSW=5

Linux modeline parameters:
"1224x688" 79.393 1224 1328 1456 1664 688 733 738 796 -hsync +vsync
___________________________________________

You should be doing this:



Now, Open the display profiles section of Powerstrip:




Open the "advanced timing" section:




Then go to "custom resolutions":




Now click the "paste timings from clipboard" button:



Then click "add new resolution"

Depending on your video card and drivers, you may or may not have to reboot.

If you did not have to reboot, you can say "ok" to letting it switch to the resolution. If you did have to reboot, go back to the display profiles screen and select the new 1224x688 resolution. You should have 1:1 pixel mapping that just fits the screen!

TV Setup:
You may not have 1:1 pixel mapping yet depending on how the TV responded to the timing.
Make sure you are using "zoom" mode and not "full 1" or "full 2".
Select "text" mode, video mode crushes blacks and whites and turns the advanced iris on (to high, I think).
I noticed that if it looks like the pixels are close but don't match exactly you may have to adjust the "Phase" setting to line it up. My TV "auto adjusted" incorrectly the first time but hit it right when I made it readjust again.
You can make small tweaks to the horizontal adjustment on the TV settings. I used this to fix my screen being offset by a few pixels. If you need to make larger changes, use the "arrows" in the "advanced timing" of Powerstrip. DO NOT CHANGE THE SCREEN SIZE USING THESE BUTTONS!! See below for instructions if you have overscan/underscan.

Now, when watching movies, I use Theatertek and set 16:9 movies to 1280x720. This give you some overscan and allows you to scale the vertical resolution of the movie exactly by 1.5. 4:3 movies I set to 960x720.

If you are using other software, or if you don't want to customize your aspect ratios, you can also use the following timing. It give you some overscan, and you probably won't be able to see the task bar or scroll bars, but it is a "perfect" 1280x720 resolution

----------------------------------------------------------------------
PowerStrip timing parameters:
1280x720=1280,80,128,176,720,27,5,44,79392,2050

Generic timing details for 1280x720:
HFP=80 HSW=128 HBP=176 kHz=48 VFP=27 VSW=5 VBP=44 Hz=60

VESA detailed timing details:
PClk=79.39 H.Active=1280 H.Blank=384 H.Offset=64 HSW=128 V.Active=720 V.Blank=76 V.Offset=27 VSW=5

Linux modeline parameters:
"1280x720" 79.392 1280 1360 1488 1664 720 747 752 796 -hsync +vsync
---------------------------------------------------------------------

There may be other timings that yield 1:1 pixel mapping, but I like this one because I can achieve a "perfect" 59.94Hz refresh rate. This is very tough to achieve with nVidia cards because the clock that controls the timings doesn't have the "resolution" that many other cards have.

Problems?
A few people have been having problems getting these to work. I think sometimes it has been that Powerstrip just isn't communicating with the drivers properly or a previous (incorrect) timing had already been applied that is still "sticking" in Powerstrip. One way to fix this seems to be to REMOVE the custom resolution and then re-create it. Another option that seems to work is to uninstall and then reinstall your video drivers.

To remove the resolution, go back to the "custom resolutions" screen, select the "user defined" bullet, select the resolution, and click "remove resolution"

Overscan/Underscan Issues
If you still have overscan/underscan you can modify this timing and still yield the same results.
Go to the "custom resolutions" screen, paste the current timing in (if it isn't already there). Now check the "lock total geometry" box. Most of the timings should be grayed out, but the resolution on top can be modified. Increase the numbers if you have underscan, decrease them if you have overscan. I believe that the numbers must always be multiples of 8. Once you have a resolution that you think will work, click the "add new resolution" button just like before.

I hope this helps you, and I'll try to update the information as people give me feedback.

Are you still using HDMI? I don't think this works at all with HDMI

Tbird, are you sure you are on "zoom" mode and not "full 1" or "full 2". The A10 will default to downsizing the screen to avoid overscan.

yes, I didn't think about that. Make sure you are using Zoom mode if you are using the VGA input.

Just a quick note to let everyone know this works beautifully with an AIW9800 on my E42A10.

It might be very very slightly overscanned, but pixel mapping is perfect and it's very readable from 10 feet even with 60 year old eyes and glasses!!

Very nice Mr.Pibb, thanks for taking the time. I did notice that these timings are slightly less than the 1232 x 696 you originally recommended (8 pixels both ways!) and that fixed me up just great.

Thanks for the tutorial. I was doing everything correctly before, but it just wouldn't work. I updated my video drivers and now it is working!

It was off center at first (by several inches), but I was able to fix that by adjusting the positioning in power strip -- the auto adjustment on the TV did nothing for that.

I've been pulling my hair out with HDMI and a 9600XT. (just got my TV last night.. im tired today..)

I appriciate the tut man. I'll try VGA tonight and these settings. Anything I'm "loosing" by going with an analog VGA vs HDMI? Other than the obvious not keeping everything digital.

Also, think this will fix the issue of the system going to 640x480 whenever I reboot? Everytime. (un-installing and re-installing CAT drivers didn't work.

Thanks man.

The only thing you "lose" are some of the video adjustments on the TV. Of course, all those video adjustments are just processing the incoming signal and modifying it anyway, so I guess you probably aren't missing much. To me the VGA input looks FAR better than the HDMI coming from the PC. It may fix the system reverting to a lower resolution. It's possible that it's getting confused by the HDMI handshake with the TV?

Thanks so much man! In about 5min everything works now!


So now PowerDVD5, XP and all look great. But now the TV HD channles are a bit odd. The people on the TV look "fat" or.. "short" a bit. I am using the ATI TV 9.13 HD software. (ATi HD tuner). It looked better before. Anyway of just changing the TV software to make it look better? I know ATi TV software sucks, but it seems no other TV software likes the ATi HD tuner yet.

Thanks man~

The ATI software may not recognize the resolution as a 16:9 resolution. Maybe use my timing for 1280x720 when using the ATI software and see if it works better. You will have overscan, but it is a more "standard" resolution. You may also want to see if there is some sort of aspect ratio control in the ATI software.

Ya thanks. I need to keep it simple for the wife. Easy way of clicking an icon to change back and forth rez? I might just use the TV tuner - but the goal was not to change inputs ever again. I assume you are using the TV tuner?

Thanks again.

Nope, just HL2DM and Counterstrike Source occasionally. It's hard to find time to play with two young kids, so when I do play I usually suck horribly.

Somewhere in Powerstrip you can make a shortcut to the resolution. I don't know where exactly (not installed on this computer). You can also set up keyboard shortcuts as well or profiles that select a specific resolution based on the program that is being run.

Yes, this is pressssiousssss.. needs pressiousss..

"Set to (that first one in the tut) always"
"Set to (that second one) for TV software"
I'll see if I can find out how.


Thanks

I have a 6600GT on my HTPC! (Ignore the ATI icon in the screen shots of the tutorial, I was doing it on my regular PC.)

For the most part this seems to work on both ATI and nVidia cards.

Mr. P.

Thanks for the tut again. Everthing is kick'n.

I decided to drop the ATi HD tuner (software sucks). I now use the built in tuner - works great. I 'll just use the ATi when I want to record something..

With these settings is it normal to watch a widescreen DVD (with powerdvd or zoomplayer) and sill have those black bars on the top and bottom? When I watch My Name is Erl or The Office on the TV tuner - those widescreen shows fill up the whole TV and look great. But on the PC the widescreen DVD movies have the black bars. I did no changes to the DVD software - but maybe I need too.

Thanks again.

mr. pibb,

first off thanks for all the detail and time you put into this guide. someone at sony should be paying you for this.

i've followed your post in the official a10 thread and this guide. my problem is that when i use your custom res in powerstrip the image is compressed on screen and i cannot select zoom mode (only full 1 is an option).

this happens when i use your 1232x696 res (from the a10 thread) and this thread's 1224x688 res. either one it distorts the image into a very small space.

your custom 1280x720 res leaves a black border in full mode (as you describe in the first topic). in zoom mode it chops off the outer 20 or so pixels.

i've read through both threads several times. i've uninstalled and reinstalled powerstrip multiple times and used different approaches but nothing works. i've ran auto adjustment on the tv many times as well but it doesn't help.

how can i get this to work?

thanks again for all your help.

i fixed it!

i think in installing your custom res from the a10 thread i must have messed something up, since it had the horizontal distortion problem with both resolutions.

so i completely uninstalled my display drivers, uninstaleld powerstrip, then reinstalled both. i then followed this guide and got PERFECT 1:1 pixel mapping without the outer pixels getting chopped off.

THANK YOU MR. PIBB!

Cool, I just finally sat down in front of my computer and saw your pm's and then your post here. I'm glad it worked! It seems like things must get "stuck" in the drivers or in Powerstrip. I'm wondering which uninstall/reinstall fixed it: Powerstrip or the drivers, or maybe it took a combination of the two.

Since the 1280x720 looked right, I knew it should work fine for the other resolutions as long as the info was being sent correctly. They are really the same timings, just with modified blanking areas to decrease the visible resolution.

With these settings is it normal to watch a widescreen DVD (with powerdvd or zoomplayer) and sill have those black bars on the top and bottom? When I watch My Name is Erl or The Office on the TV tuner - those widescreen shows fill up the whole TV and look great. But on the PC the widescreen DVD movies have the black bars. I did no changes to the DVD software - but maybe I need too.

Thanks again.

First, many widescreen DVD's are at an aspect ratio greater than 16:9, so a bar on top and bottom is normal on many of them. Now, if the bars are on the side then you need to adjust the aspect ratio in your software. I know this can be done in Theatertek, but I have no idea if it can be adjusted in other DVD playing software.

it was uninstalling and reinstalling the display drivers that fixed my problem.

so if anyone out there is getting a horizontally distorted image that's what you need to do.

The only screen modes I have listed are 'pixel x pixel', 'full1' and 'full2'.

I have been trying to feed different resolutions but it goes 'out of range' whatever resolution I choose.

1024x768 is the only one thats working.

Could it be due to the tv being the european model A11?

Is there any fix (service menu) that could remedy this dilemma?

Hmm, it could very well have something to do with it being the A11. I know I don't have a "pixel x pixel" option in the menu anywhere on mine.
verify a few things for me:
You are using the VGA input, correct?
You've followed the procedure listed above?
You've added the timings listed above?
Have you tried uninstalling and then re-installing your video drivers?

In addition to my timings above, you may want to try some of the pre-configured Powerstrip timings. there are quite a few that are at least close on my TV. Most of them. Try timings that are around 1280x720. Some have had decent luck using 1280x768 timings to get started anyway.
