I bought my set a few days ago. Hooked it up to an nvidia fx5200 card on my htpc (also connected to my projector pan lt500). I used a 25' VGA cable with ferrite cores for the connection. The text looked a little muddied at 1360x768, so I upped the sharpness on the set and it looked fine. a sample WMV file with HD-WMV looked great!
I tweaked my beyond tv settings to change the interlacing - to deinterlace the Standard def pictures. and that improved the quality of the picture on it. A decent SD picture (of course, it's coming from my hard drive / comcast).
Next up was a true HD test, so I downloaded the latest mariposa episode from **********. I noticed multiple horizontal lines in the image along with a "scan line" moving upwards. So I updated my nvidia drivers (yuck, liked the old ones). Now the problem was noticeably worse. Same picture on my 1280x720p projector was stellar.
So I adjusted the settings to use 1280x720p as an output on the olevia as well. Everything looked fine and no white horizontal (tearing?) lines at that point. Image was too small though.
So I adjusted the olevia to use "full screen" rather than 1:1. Replay image - perfect - no tearing. So my guess is the 5200 card couldn't convert the odd resolution.
I haven't done any proper tuning, but it looks pretty good.
