Default Re: Quadro 4000M: Internal display flickers with drivers from 290.10 on

I therefore think this problem is related to bug 938124 described in this thread: http://www.nvnews.net/vbulletin/show....php?p=2552723. Perhaps the failure to properly turn off the screen somehow triggers this bug? New bug report for 295.53 is attached.
Just to make sure this doesn't fall through: For me with the Quadro4000M and HP 8760w "DreamColor", the issue most certainly is not related to DPMS.

I can readily reproduce the problem with my current 295.49 within minutes after logon and constant work, i.e. no screensaver/DPMS.
