    I've used my CRT RP with my laptop; set the resolution to 640x480 @ 60hz (NTSC) and it looks very clear- text is nice and sharp. However when I set to 800x600 it goes a little blurry. I understand the TV is downscaling the 800x600 image to 640x480, as normal TV resolution is 640x480?

    So if/when HDTV CRT RP sets come out, what resolution will they support? Possible to choose 1024x768 @ 60hz (NTSC)?

    S-Video. My laptop has VGA output, but my RP doesn't have VGA input.

    Although at this rate (when HDTV sets are released) I'll probably buy a new laptop with DVI/HDMI/Component or whatever is out.

    If you are sending S-VIDEO then it's not getting a progressive 480P or 600P signal at all. The laptop os downscaling to an interlaced output of some description. It looks softer on higher res desktop as the downscaling is not that great I guess.


    Normal TV is 720x576@50Hz, interlaced
    or
    720x480@60Hz, interlaced.

    Hi Def rear pro's in US have 1080i and 720P input capability. That is to say they will accept such signals and display an image. Some turn everything in to 540P others try to show images natively. Very very few are actually capable of resolving all the detail in the signal

    Thanks for the info Gordon. So if I use Powerstrip with my current machine and set the resoultion to 720x480, it should look even better? (as it'll be 1:1 pixel)
