Duh, after reading this several time, I now realize there's a typo. It should read 320x240. No trick;=) This is for output to the RCA or S-Video ports. Using the Monitors Control Panel, you set the TV monitor resolution to 320x480. I don't really know how the doubling works, but this output effectively puts one pixel where four should be on the TV. Of course, on a TV you can't see the pixels distinctly. I think only the 8500 has this feature. I'm sure someone else on this list would have more technical details. Just found this on: <http://www.sims.berkeley.edu/~jwang/cgi/av-faq> "Special hardware interpolation for video-out is also available on the 8500/8600. For example, by selecting the half-sized 320x240 NTSC resolution for video-out, a likewise sized movie would be smoothly interpolated in the horizontal and vertical directions to the full 640x480 television frame. The resulting picture is of much higher quality than software-based pixel doubling, and incurs no CPU processing." _ Andrew -- -- PCI-PowerMacs is sponsored by <http://lowendmac.com/> and...
