First off, I recommend getting the RTM, not the Beta. Might be fixed if it is the bug.
I thought so too, but I have a retail version
Second, monitor drivers
What type of monitor is it? VGA, or [COLOR=#0072BC ! important][COLOR=#0072BC ! important]DVI[/COLOR][/COLOR]
I'm running dual CRTs. I've updated the driver
. The first from the card manufacturer didn't install correctly. I called Gigabyte and they said to use the Nvidia driver from their site. That didn't help, but did screw up the colors, even with profiling the monitor. So, I reinstalled a different driver.
I flashed the BIOS the other too
Third, do you have that set in the power option that is active?
The power setting is set to turn off the monitor after 2 minutes, but no go.
