I have a 46" panasonic vierra HDTV 720p. My htpc is plugged in via hdmi and my problem is no matter what resolution I do it's either too big and the screen is cut off or it's too small and there is a black border all around..
Any special ways you guys sync up your htpcs with the HDTV so it fits just right without being too big or a black border all around..

If you have an Nvidia vid card, you can resize your desktop, and it should fix your problem

Nvidia control panel, Display, adjust desktop size and position, size, enable desktop resizing
Then click resize.

Try using the standard 720p resolution i.e. 1280 x 720. You'll probably find the edges of the display are cut off. This because the TV has overscan enabled. In the TV menus somewhere there may be an option to disable overscan. If you can't find it post the TV model here and I'll have a scan through the manual (assuming I can find it online).
With overscan disabled the TV should behave like a PC monitor and give you a 1:1 pixel mapping. This usually gives the sharpest picture.

You should download your screens manual and it will tell you in there what resolutions and refresh rates it does over its various input types
Your only get 1:1 pixel mapping running at your screens native resolution and this will produce the best image by far maybe not as noticeable during video but everywhere else it will be more obvious especially text
Screens vary greatly more so on older screens as to what they accept over each input type if your lucky your get native resolution over HDMI supporting all the needed refresh rates but I would be surprised on a 720p panny if it didn't need 1920x1080 for 24Hz

Thanks everyone, one htpc down one more to go. My other htpc has an on board gpu and it's an ATI radeon HD something I forget the numbers anyways now I gotta play with those settings to get that one to fit right.. I will have time after work today for that one..
Now my tv does not have an overscan setting like some of you suggested so I assume you mean the pc does.. Because i did see over scan and under scan in the nvidia control panel when I was playing with that last night.

It probably wouldn't be called overscan on your TV on my screen its dot by dot mode but in any case it should only be available if you use the native resolution
I have another screen which happens to be a panny and it doesn't use overscan when I use the native resolution anything other than using native and it does
I'm not sure what model you have but some of the 46" pannys that were 720p had a native resolution of 1024x768 just as the 42" I have has if that's the case then that's what you need to use to stop overscan and get 1:1 pixel mapping it will be in the manual what input it will do that over mine will only do that over VGA at 60Hz
You would also need to adjust "Pixel Ratio Adjustment" in XBMC to 1.333 if you had to use 1024x768 because its a 4:3 resolution as far as your PC is concerned
The image I get from native 1024x768 over VGA is better than anything I get over HDMI
