How to adjust screen on LCD HDTV on HTPC?

I just got my HDMI/DVI cable and hooked up my HTPC to my tv with it (removing the old S-Video connector). I finally got the clarity I hoped for; text is super crisp! But now the problem is that the screen is "out of wack". On my regular LCD for my other PC I would just hit the auto-adjust button and all would be fine. How do I do that on an HDTV?

The TV is a 720p HP LDC HDTV. If I remember right (I did this last night), the resolution was set at 1280 x 720 (or 768).

Under screen res&refresh rate try checking the box for "show standard HDTV formats" and pick 720p. If that doesn't do it, you will need to click on the advanced timing tabs and manually set it up.

I had trouble with the DVI-to-HDMI and a RP CRT HDTV, but it was the TVs' overscanning at fault.

Hmm, I remember checking the box for the "show standard HDTV formats" last night. What settings exactly am I looking to manually set it to?

You probably have the same situation I do. My TV is 720p with a native res of 1366x768. The HDMI connection won't accept 1366x768, even after defining it as a custom resolution.

You have two options - adjust the under/overscan, or use a standard VGA cable. I know it's an "old" connection, but the VGA might be the best bet. It will let you use the panel's native res, which will do 1:1 pixel mapping - which I don't think will happen with HDMI. Even with under/overscsan my HDMI connection didn't look quite as "crisp" as VGA does.

1360x768

If you've corrected any scaling issues in the PC software and on the set itself (as others have mentioned) and still have a problem at that resolution, then try the VGA input (also as mentioned). You'll lose 3 pixels on either side, it should be something you can live with.

My 6600 will do 1366 for 1:1 pixel mapping. Don't see why his won't. Why lose 6 pixels if you don't have to?

I don't know where in the hell you are getting this Info. My DVi to HDMI works perfectial 1:1 pixel mapping of 1366x768 and it looks way crisper than VGA ever did.

1360x768 is just the common res for 1:1 over HDMI/DVI on these 1366x768 displays when full res is not available due to driver limitations. In addition to defining custome resolutions, a lot of people use Powerstrip. I believe it's mainly older cards that have this limitation, though I run a 1080p display so I'm by no means an expert.

VGA vs DVI is a topic in and of itself. Personally, I prefer DVI to keep the signal digital as the display is digital; but which is best depends on the implementation for the display. It is recommended that you try both to see which is better.

Why so antagonistic?

I said he probably has the same situation as me, IE, his TV won't accept 1366 over HDMI. When I force that custom rez over HDMI my display (Vizio VX37L) I get a scrambled image. Just because it works great on yours and not on mine doesn't mean it will on everything, and vice versa.
