Thanks all!
I used Powerstrip to add custom resolution to 1366x768, it works but i have to underscan to match exact borders of my tv set

    During some research I came across this. It may assist with determining your screen's 1:1 mapping capability. But also, check the last paragraph regarding your set resolution. It may give better results than the underscanning you have.

    Hi everybody,

    some news about my quest:
    i succeed to fit my desktop to my PDP borders with 0% overscan, but not with the native resolution.

    First of all, i created the new resolution 1366x768 (native resolution of PDP) thanks to Powerstrip. I applied this one but it does not match exactly -> i had to underscan with CCC.
    My PDP is set by default to 16/9 mode view. I have noticed that if i want to fit exactly without underscan, i have to select Zoom 3 mode view from my PDP.

    After that, i decided to try others resolutions to fit exactly without underscan in 16/9 mode and i have found this one:
    1216x684 (720P)

    It's not the native one but it seems to work.

    Do you know why?

    How confident are you that the resolutions indicated are actually the resolution sent to the TV? As I posted before I would suggest you run monitor asset manager to see what your set supports. My guess is that you are connected with HDMI and regardless of what you select you are sending 720P or 1080 and the set is rescaling it…

    I think that you will find that you can do no better than driving it at one of the two listed "native" timing modes.
    1280 x 720p at 50Hz - HDTV (16:9, 1:1) [Native]
    1280 x 720p at 60Hz - HDTV (16:9, 1:1) [Native]

    Which I think you may have already concluded
    The Pana TV will scale to the panel resolution…
    In my case, and I suspect your case, the TV will not accept any resolution or timing that is not listed on the “supported” list.

    Yes, i agree but when i select 1280x720p, i have to underscan to fit borders. I don't understand if it's the native resolution.

    Yes, the TV will slightly overscan to prevent you from seeing edge or boarder artifacts. I have Nvida graphics and it will allow you to pad the outside edges to fit the picture exactly on the screen. The issue I discovered when doing this is that broadcast TV expects the overscan, broadcasters place some low bandwidth digital content in the overscan picture area which shows as blinking pixels. I have since decided to leave the overscan on. This is a carryover from analog broadcast. Too much trouble to change it depending on the content I am watching.

    Just to clarify it is not your “native” panel resolution, but it is the “native” resolution the TV reports to your video card.

    1280x720p too much underscan to do
    1216x684 fits exactly with no underscan

    Finally, i set resolution 1248X700 50Hz. I have good picture, no underscan, picture does not fit exactly but it's acceptable.
