: If I'm not mistaken, s-vid out on ati cards will support 1024x768 or lower. However, it's never gonna be true 1024x768 since a tv simply dosen't have enough lines of resolution to display it. So your answer is yes, but it dosen't matter anyway. As far as "true" resolution goes I don't think you can even get as high as 640X480 on most monitors, the vid-out simply blurs, "analogs" and compresses the image so it will fit.


If you have a good TV, the specs are often rated between 600 and 800 lines of resolution. I do a fair amount of video work with computers, and the common resolution specifications for NTSC are 720x480 (or 486). This means that anything up to that is pretty close to "true" resolution, again, on a good television. As you said, the major difference is the per-pixel color purity that can be achieved with a combined signal, but don't discount the grossly large dot-pitch of a television set as opposed to an actual monitor.

I use an ATI Rage Fury, and anything above 800x600 forces the "pan and scan" mode. So for me, 800x600 is the absolute max for normal full screen, even with compression. For what it's worth, however, the 800x600 is close enough to the "actual" resolution of the NTSC standard, so that the compression isn't too objectionable.
