View Full Version : Sun Monitor Question

09-24-2002, 01:25 PM
I have always thought that Sun monitors were not compatible with macs. Well, in a local goodwill computing store I found an apple 15pin monitor cable with a Sun monitor connector on the other end. Curious, I bought it and a cheap 20" Silicon Graphics monitor to check it out. It didn't work, but what then is that type of cable used for? To connect an apple monitor to a Sun workstation? If anyone has any ideas, I'd appreciate it.

fwiw, the Silicon Graphics monitor has the same button layout, CRT, and case as my Apple 20".

Tons of times, workstation monitors are fixed-sync varieties of very similar multi-sunc brethren. I have 2 20" Sun GDM-20D10 monitors running on my Macs. They have Sun's wacky 13W3 connector. In my case, the adapter needs to have a 2 microFarad capacitor soldered between 2 wires in the adapter to allow it to sync at all. Your case will be different I am sure.

Here (http://home.iae.nl/users/leibbran/sunmon/sunmon.htm) is the Sun conversion page. And here (http://www.monitorworld.com/) is a decent place for monitor conversion info.

Hope this helped a little. Not sure what the adapter is for. Even Apple borrowed Sun's 13W3 for their Portrait Display. Companies find odd uses for each others technology. Wish I could help there.

Thanks, those sites are great. It is a GDM-20D11, and according to the site, a multi-sync monitor. More importantly, it states it is a sync-on-green type. I connected it to a built-in Mac monitor connector and a Proformance 3 with SVGA adaptor, but maybe I'll dig out a Twin Turbo with sync-on-green and give that a try before doing anything else. Thanks again.
