[X4U] Problems with aged screen

[Jonnythan]

Hello everyone,

I'm trying to get my girlfriend's old 14-inch Fujitsu C500 monitor working
with a G5. The monitor currently works fine with a MacMini, and the G5 has
been fine with an Apple 20-incher. Both systems are running OSX 10.4. When I
connect the Fujitsu to the G5, the screen won't come to life.

I've tried zapping the pram 3 times without success.

Any suggestions please?

Jonnythan.
