The problem is the Apple IIgs uses a 15khz Horizontal Refresh and
Nearly All modern monitors use a 31khz Horizontal Refresh rate. To
hook up a modern monitor to a iigs you need to wire up a iigs to vga
adapter and double the horizontal scanrate which most products that do
that are about 100 - 200 dollars
Or you can purchase a early multisync monitor like the NEC Multisync
3D. IT MUST support a 15khz Horizontal Sync. What I use is a XRGB-1
Upscan Converter. The model that is being sold now is a XRGB-2 Plus
Upscan Converter.
