I was doing some testing with a similar HDTV and found that a video frame of 1280 x 720 did a good job.
High resolution (like 1920 x ???) comes with a penalty of large file sizes with little difference in appearance.
High Refresh Rate ... I can't see that being necessary.
Keep it normal to start with.
Try it later, after you get everything else worked out.
What brand/model video card are you using?
I was looking at some specifications and found them vague about the type of HD connector.
Got a new vid card so that I can connect my media center pc to my HDTV via HDMI. Yay! Hooked in, and I'm ready to watch some HD files from my hard drive... Mmm, blue planet... now what windows settings do I want? Is the highest resolution best (1920 x ?)? Native resolution for the TV (1300ish?x ?) Something else? Refresh rate as high as I can get it?
I'm a lil short on specs as I'm at the office, but let me know if thats necessary. Also, I have vista.
