Hi,

After I have upgraded to the latest video drivers from Dell download site, whenever the laptop wakes up from sleep the screen flickers wildly for about 10 minutes. The flicker gradually fades. First there are even visible horizontal lines. It seems like the display is set to 40Hz refresh rate but in the resolution panel and the nVidia control applet the refresh rate is 60Hz. With the old driver it worked but I have upgraded because the old driver sometimes crashed the laptop. Is there any setting I can make to get rid of this flickering problem?

Thanks!
