That's a slightly controversial question. 24Hz definitely not. A couple of knowledgeable people say they've managed to get it to accept a 48Hz signal from a PC using Powerstrip (over HDMI, that is, not VGA). At least one knowledgeable person was not able to get it to accept a 48Hz signal from a Lumagen scaler. So, if this matters to you, it would probably be a good idea to test it out (using the actual hardware you're proposing to use) before you buy.
The picture has full 1080p resolution with 1:1 pixel mapping, but with some optical overscan, so the edges of the picture are beyond the edges of the screen. In addition, it will only accept 1080p usefully over HDMI. Component is limited to 1080i, and 1080p via VGA is displayed incorrectly (downscaled).
I will use dvi to hdmi. I'm gonna use my pc for HD movies (.mkv .avi) and hd dvd and games with this tele. On the fly hz (48 to 60) switching would be great. I think i can only get 1080i out of that £10 philips dvi to hdmi cable i have. I'm still waiting to buy this tele.
