I started another thread
on a problem I've just noticed, but I suspect it is related to what is being reported here.
Update: This morning I booted up to logon and the external came on, although it flickers like crazy. Then after a few minutes it went blank. Recalling the heat issues people have mentioned here, I put my fans on max via Fn-F10 and... the external display came back almost immediately - it did not wait for temps to go down (I wasn't running MobileMeter at the time so I don't know what the temp was when it wasn't working). I am using it now, with flickering and resolution issues, e.g. some lines of type are blocky. As soon as I hit Fn-F10 to set the fans back to auto, the flickering immediately gets worse, again, apparently, unrelated to the actual temperature of the cpu/mobo but to the setting of the intake fans
. I suspect that if I leave them on auto the external display will shut down again.
I have an early model 8790 purchased in March '04, upgraded to the WSXGA+. I've never had artifacting on the laptop LCD, but then again I don't tax it with the kinds of games mentioned here, mostly Half-Life 2 Deathmatch and Anarchy Online. I'm gonna mess around with the drivers a bit, but I just wanted to post my experience here to add to the knowledgebase.
