Wow, this TV is frickin' incredible as a PC monitor.
Okay, I at first was having some troubles with getting the overscan taken care of after setting the PC resolution to 1920 X 1080 (60 Hz), but then I found a little control on the TV called Aspect, and what do you know, there's a PC setting there! I set it to that and wham, perfect fit.
I tiled the display test image that was linked earlier, and I can make out black and white lines up close, so I believe it's 1:1 pixel mapping even.
The factory settings for Studio are almost perfect, I notched the brightness up to 51 from 50 and that was about it.
Oh, and did I mention it has a DVI mode control with two settings: Default and PC. On default you get video levels (16-239) and on PC you get PC levels (0-255). So it's that easy to switch video level modes for HTPC users.
They built this thing to be used as a computer monitor, no doubt about it.
The greyscale is fantastic - I loaded up a greyscale palette and can notice the graduations between each step. Black is freakin' black, and white is bright as hell.
The only problem I've had is with the delivery. The assclowns (can I say assclowns here?) forgot to leave the remote/power cord/manual/warranty. They have the worst hours imaginable (they don't deliver past 3 and only M-F), so I had a friend housesit while I was at work. They brought the TV in, set it on the stand, and took off without even plugging it in and making sure it worked. And with those important items.
Fortunately it's a standard PC power cord (gotta love HP), and I just stole the one off the other computer to use for now.
And the front connection panel is sweet as hell. Very good design.
Sorry if this post isn't sounding all that educated, I"m just very excited (and angry at the delievery crew) and I wanted to get my impressions down as fast as possible.
If you HTPC and don't see rainbows, get this TV. Otherwise, get it anyways.
Attached is a close-up picture I took of the test pattern.
