I'm not looking for a potted answer here - just ideas for where to look. Is ~28KHz a
common HSYNC frequency? seems too low for anything I've seen.
What else should I look at for a non-syncing monitor? USENET seems to indicate 48.8 KHz
HSYNC on these old SGI monitors (SGI employee posting),
so I'm not sure where the ~28 KHz is coming from- is this crystal or RC controlled?
There are about 9 boards in the graphics half, I suppose sync is generated
on the last one (in this case the DC4 display controller) - no crystals there.
Common failure on old framebuffers? any tips? tony?
