I have a ViewSonic N2750W which I currently use for just a TV (I can't recommend it for a standalone TV), but will soon use it for the display for my bedroom HTPC.
Its a 720p display, and I had it connected briefly to my Living room HTPC for testing. It has steller specs, but I suspect they are exaggerated.
I found it very nice for a PC display, and gaming was very nice as well as the desktop. I didn't notice ghosting in my short amount of testing, but there was plenty of WOW factor seeing HL2 at 720p on a 27" display (I use a 22" CRT for gaming), although it was a bit close on my desktop for ideal viewing.
HDTV PQ was excellent IMO, blacks are a bit on the gray side however, but still very nice. Analog NTSC PQ was below my CRT's, and the gray-blacks take bigger toll than with the HDTV, but still pretty good with a proper viewing distance.
The key is viewing distance, and at ~ 3', this 27" is an excellent HTPC display with good connectivety. I can recommend this particular model for PC use, but you'll want to research carefully as pricing and a number of models available make it a chore to get the right display.
