PC to HDTV through HDMI scaling problem

[Dragos Costache]

Hello. I have a Sony Bravia KDL-32P3000 LCD TV, that I use as secondary monitor when I want to watch movies. It's native resolution is 1360x768, but it supports resolutions up to 1920x1080 interlaced.
When I connect the PC through HDMI to the TV, and set the resolution to 1920x1080, the desktop's edges can't be seen and the text and graphic elements are blurry.
I read that this might be an overscan issue, but I didn't find how to disable this on my TV (there should be in the menu an option called Full Pixel, or something like that).
I would like to mention that if I connect a PS3 through HDMI, the image looks perfect at 1080i.
My graphic card is a nVidia GeForce GTX560 Ti, and I use the HDMI cable that came with the TV.
I hope you can help me solve this problem, 1360x768 isn't a very good resolution for a 32 inch "monitor". Thank you in advance.

It's preferable to have the TV settings to something like "Just Scan" or "Full Pixel" or "1:1 Pixel Ratio". If the TV doesn't have any of these, then you should be able to find some scaling settings in the nVidia Control Panel.

I've tried to use the nVidia scaling in the driver, but that doesn't change anything.

Then you're gonna have to use a custom resolution.

I've also tried "resizing the desktop" from nVidia driver and it got me to a resolution like 18aa x 9aa, the edges were visible, but the the image was still blurry.

I believe the blurriness is from the picture being interlaced.

Then I don't understand why does the image look very good when I connect the PS3 in the same port with the same cable at the same resolution.

Because a console is designed for this. PCs really aren't good with interlaced video, if I'm not mistaken. Maybe if you fired up a game, it would look just as good.
