When connecting an Optiquest Q22wb Monitor to my Power Mac G5 using a DVI-D cable, there is an intermittent problem where the computer will lock (either sleeping or going to screensaver), and when I wake the computer, I see the usual unlock screen, however when unlocking it I am presented with a black screen.

If I select "switch user" instead, I see the normal user login window. It seems anytime I try to access my user profile, the screen is black.
The only solution I have at the moment is to restart my computer.

This issue does not exist if I use a VGA cable from the monitor, to the adapter for the Power Mac.

Here are the specs.

Any input would be helpful!
(Please don't tell me to just use a VGA cable...)

Well I wo't tell you that then.......................

Hang on to those original install discs like grim death! Using OS X.7 or later make a bootable USB thumb drive before running Installer!

Hmm this is a stumper. Can you try dropping your resolution and test again and see if that has any change? Try this with your DVI connection.
