Second monitor goes blank

wkirkham · 11-23-2010, 04:08 PM

I'm having trouble with my second ASUS display going black after a while. Then the LED on the link adapter turns off. I can sometimes get it to come back on by unplugging the USB plug and replugging it in. I'm using the latest beta driver, 1.6b3 (27768)

After I posted this, I realized that I had just updated my OS to Version 10.6.5 a few days before I noticed this problem. (I don't always run with both displays on, so I didn't realize the problem at first.) My original update was through the Software Update system on the Mac. So it updated from Version 10.6.4 to 10.6.5. Just to make sure that it was not a update problem, I ran Disk Utility to check the disk for consistency and repair permissions. Then I downloaded and ran the 10.6.5 Combo update, which would update a 10.6.0 installation to a 10.6.5 installation, several upgrades all at once. Then I rand Disk Utility a second time to verify the disk and repair permissions. The second monitor has been up and running full time since then with no problems of any kind. I waited a few days here before declaring victory, so it seems a solid fix.

(Now just watch it go blank when I hit "submit." lol)

premature! Still goes blank at times, even while in operation. Sometimes it moves all the windows onto the remaining monitor, sometimes not.
