Hi Werner, > Here is a first impression of what this looks like: > http://downloads.qi-hardware.com/people/werner/ubb/vga/ubb-vga2-first.jpg wow this looks great. What kind of resolution is possible with this approach? You're still using double-scan (sending every line twice)? Guess we could use the extra pixels to do some dithing for showing more colors. Maybe even some temporal dithering, if the flicker is acceptable? > The timing is more accurately VGA than what I had before.

Maybe we'd need a kernel driver processing an interrupt once per line or once per frame, then locking the CPU for the VGA data transfer. How much %CPU would that leave for programs to consume? Just speculating how your code could be reused as an mplayer vidix video-out driver :) David -- GnuPG public key: http://user.cs.tu-berlin.de/~dvdkhlng/dk.gpg Fingerprint: B17A DC95 D293 657B 4205 D016 7DEF 5323 C174 7D40
