Nvidia Full Screen Video Problem On 32" TV When Playing HD Content

[Macron]

Hi all.

I have a PC with an Nvidia 6800 Ultra AGP with dual DVI out connected to my new LG 32LC2DB 32" HDTV via a 10 metre long VGA cable and DVI to VGA adapter on the PC.

I also have a standard 17" TFT connected via the same method.

The TFT is set to 1280x1024 @ 75hz. The TV is set to 1360x768 @ 60hz in dualview mode.

The picture quality is fantastic on both.

The problem is that if I set the Nvidia Full Screen Video option for the TV it will play most movies fine, but not HD movies.

E.G it will play all my standard mpegs etc.. no worries, if I try to play a video downloaded from the Microsoft WMV HD showcase it just says "no signal" on the TV.

If I turn off full screen video mode and just drag the HD WMV onto the TV and maximise it, it plays just fine and looks great too.

I have tried new graphics drivers (with a clean install using drivercleaner). I have removed all my video codecs and re installed clean ones. I have tried every single media player I can find. Nothing seems to fix this.

I have also done a factor reset on the TV and tried every setting there is.

DVD's play fine if I manually drag the window over to the TV and maximise it.

I can live with this but I would love to have HD content auto play in full screen on my TV.

Any ideas?

i have simmilar set up as you.but i have my nvidia settings set to single display. and set a hot key to change displays, i have my 32 hd tv set to 1200x720 i think that setting is best for hd dvd,i play a few hd films through media player 11 and the play perfect,by the way my card is a 7900gt.

So should I be using 1200x720?

I thought I should use the native res of 1360x768 or whatever?

[Macron]

Okay so it doesn't look centered at that res.

Interestingly enough I read the manual today.

It says I should be able to change between VGA and XGA mode. But VGA mode is not there, only a list of XGA resolutions.

Anyone know why this is, should I be in VGA mode?

Dual view on some cards matches the refresh to the main display, which could cause you a problem.
Have you downloaded power strip and played with that.
I have the same TV and can play HD video from my laptop. Have you done an Auto configure from the TV menu when you get the no signal?

VGA mode is 640x480 so no you don't want to use that for displaying HD.

Have you tried making the TV the primary display?
