Might want to check your refresh rate. Used to have an ATI Rage 128 Pro
running a MAG LCD monitor at 75 MHz. When I finally dumped that card for a
Ti 4200 I had the same problem until I changed the refresh rate to 72mHz.

Worked for me, but your mileage may vary.

Hi all,

I have an A-GX20 (Chaintech) and every 5 minutes or so (when on the
computer), the monitor blacks out and then comes back after 10 or so
seconds. The mainboard is an Asus P4SDX. Has anybody experienced
this or have a solution.

Thanks
