I've just aquire one IBM 6091-23 monitor and one IBM 6091-19 monitor.
Both are fixed frequency monitors used in Workstations (RS-6000).
They can display 1024x1024 and 1280x1024 resolutions with H freq of 63.360Khz and 70.75Khz and V freq. of 60Hz and 72Hz. Dot clock speed are 89.2 Mhz, 111.5 Mhz and 120 Mhz.
Their input are 3 BNC: R G B and the sync is in the G channel.
I know there are several fixed freq. video cards than can make those monitors work, but are very expensive.
How can I use a cheap video SVGA card to produce Sync on the G channel, and make the monitor work?
I notice someone had the same problem last year in this forum, but the accepted answer didn't solve the problem.
Thanx for your time and knowledge.
