Have you checked the cmos settings to make sure Standby mode is not enabled
in Power Management? Standby mode makes monitors turn off after a given
amount of time. Windows also can control this feature in display
properties. I have my monitor set to turn off after 20 minutes of
inactivity.

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
