I moved my Dell E510 P4 3.0ghz with Radeon x300 DVI into the living room and hooked it to my Vizio 50 Plasma via HDMI.
Before I tell you my Vizio problems, you should know that I runn this PC to a 24" Dell LCD at 1920 x 1200 and it is crisp.
While others say they run their HTPC at 1920 x 1200 to the TV, I was unable to, well kinda. With the DVI to HDMI cable connected to my Vizio 50 Plasma, I could get the 1920 x 1200 resolution, but it was totally unreadable. I had to drop down to 1360 x 768 to get a fairly clean screen, but still not near as clean as my Dell LCD. I went ahead and fired of MCE live TV at both resolutions both were noticably crummy compared to the normal cable feed going straight to the TV.
Now this unit is my desktop and it works great as such. I would purchase new equipment for a HTPC, but I want to justify that I should do this first.
What do I need to do to see the cool HTPC experience like others claim with the 1920 x 1200 crisp resolution?
Is my Vizio the limitation?
Vizio P50 model. 720p, 1080i, 1366 x 768 native resolution.
Is my ATI Radeon the limitation (it works for the DELL LCD)?
Why at the native resolution, does the MCE Live TV still look worse than comcast cable going straight to the TV? ( MCE Live uses HDHomerun tuner)
