I spent most of Friday setting up the TV as my computer monitor. Unfortunate that the PC input is restricted to 1024x768. I ended up getting an ATI X1050 graphics card to replace my old one. This was only about $100 and I needed an AGP cause my MB is quite old. Just trying to get it to work, nothing fancy.
The key as others have pointed out is getting the latest drivers off the ATI web site. Then, using powerstrip to tweak the display so it fills the screen. The end result is nothing short of amazing. The powerstrip settings I used were pointed out in this thread about a page back.
Only a couple funny gotcha's still biting me. I don't seem to be able to have the graphics card send the same desktop to both the VGA output and the HDMI output. So, my HDMI display on the TV is the primary Windows display, and then it continues on to the VGA display to the right of that. I may need to go into powerstrip and fix that, haven't checked yet.
Another funny result of this is that when the computer boots up before the powerstrip settings kick in, the TV tells me that I have "unsupported signals" on the HDMI input, and no picture is displayed
This initially threw me for a loop cause my welcome screen was missing. I was finally able to search around in the blind till I got lucky with the mouse clicking and Windows booted, then the screen magically appeared. I then set the "welcome screen" off, and it comes up directly to the logon window. Since my username is pre-populated there, about 1 minute after I power the computer on, I just blindly hit "tab" then "enter" on the keyboard and then about 2 minutes later a miracle occurs and the Windows desktop appears.
Another funny thing is that about once every 10 minutes or so the screen flickers off/on really quickly. This doesn't happen with the other HDMI input (Tivo) so I assume that the video card is either not set exactly right, or this is the end result of just spending $100 on a video card.
If anyone knows how to just have Windows auto log me on please let me know. I don't want to take the thread too off course, as I'm sure this kind of info belongs more in the tweaks thread. I just wanted to let other owners out there know that it can be done.
