so here's the deal, after leaving my imac (latest 24 inch) on standby for about an hour i start it up and there's a MASSIVE vertical gradient (ie top MUCH darker than the bottom). i restart and it's still here. I get the impression it's a software malfunction rather than a hardware issue as for a split second on start up it appears normal. I'm completely mystified by this as it is working perfectly otherwise. Some more details....
IS affected by brightness control
"white" on the effected area appears very dark grey
Any suggestions would be HUGELY appreciated. Thanks in advance and I'll keep you posted if there's any developments.
I should probably also mention i have the NVidia GeForce 8800 GS
