It could be settings on either. It's especially difficult after a driver update to conclude that the driver didn't cause a feature to stop working.
Check to see if sending the signal straight to the television fixes the issue, rather than cloning the screen.
I'm not sure if you're connected via DVI/HDMI or D-SUB 15-pin. But you might try toggling through the picture size settings to see if that produces a different result.
I have seached for the answer to my question on this forum but it seems that I am the only one having this problem.
I have connected my PC (WinXP S2, GeForce 7900 GS) with my Samsung tv (LE40M86BD) and it used to work fine. But I have just reinstalled some hardware drivers and now my TV only shows some of the screen.
Before it took my 1280x800 resolution and if I used "Clone" screen in nVidia it would show the whole image on the TV. Right know the image is using the whole screen on the TV but it only shows part of the image, the lower part is missing like the Start menu.
I have tried a lot of different things and nothing is working. Where could the problem be? TV or PC?
