I'm having this problem too. I have an older Sharp LCD TV that's 1366x768 native. Now, here's the weird thing, the TV doesn't advertise that it supports 1366x768 even though it does, so I had to create a custom resolution on XP. So, even though the TV didn't advertise it supported 1366x768 (via EDID I suppose?), on XP, the nVidia Control Panel let me create it and use that resolution and everything worked swimmingly. However, on Windows 7, the nVidia Control Panel won't let me create the custom resolution, it keeps insisting it's not supported. And I suppose technically it isn't supported by the TV because it's not even in the user manual, but like I said, I know it actually is because I used that resolution when I used to use XP.
I was using nVidia drivers 162.xx on XP and using 190.xx with Windows 7. I tried downgrading to 162.xx with Windows 7 but it won't let me use Aero if I do that so I didn't even bother trying further. Is there any trick in Win7 to force a "non-supported" resolution when creating custom resolutions with the nVidia Control Panel?
EDIT: I'm using a DVI-D connection by the way with a nVidia 6200, and the SHARP TV is the LC-37D5U

I got the EXACT same problem. Under WXP everythin worked fine for me too. Under W7 I can only create 1369x768@50hz , 1366x768 can not be created.
Specs: 8800gt, Toshiba 32 LCD
PLEASE HELP!

check this thread out, it helped me out a lot.
you could try to force it through RivaTuner
Some graphics cards do not support certain resolutions. My monitor is 1366 by 768. It is only in HD when it is at this resolution (this is it's native one), and any other resolution it is set to blurs the screen a bit.
