Hi,
I'm repairing an medium resolution monitor (Sanwa PM1745) for a friend, and now I have to test / adjust it. does anyone know of a way to make a test signal for this type of monitor.
All the games I have are standard resolution :(

I was trying to use a PC with mame and ArcadeVGA, but I don't seem to be able to sync the monitor :(

Please help....
 
You need to find a board that outputs med res or ega resolution. If you plan on doing this sort of thing a lot wells have a signal generator that will do the job.

Yep. I have a partially-working Blitz 99 PCB that is dual-res switchable and has a test grid and color bar screen in the test menu that I use.

My problem is that I often don't have the proper yoke for testing...
