vampir Posted January 31, 2008 Report Share Posted January 31, 2008 Hello! I asked on this forum for help regarding driver problems on my Acer 5920g. Since no one had any idea how to solve it not only here but also on other sites and forums I want to share my solution with anyone who may still experiencing this problem. Apparently some series of Acer notebook came with BAD_EDID laptop display. The only thing wrong is the checksum which is 9D and should be 1D. Powerstrip 3.76 (registered version) managed automatically to correct EDID. There is no problem with drivers from 101.x series, but with any newer driver max. resolution is 1024x768 and the picture is in left upper corner of the screen with black bar on the right and smudged taskbar to the bottom of the screen. After installing and restarting resolution is set to 800x600 what results in white screen whit thick black bar slowly appearing on the screen. I hope this will save someone some time, because I was about to send laptop to service when I figured that out. Contacting through e-mails and phones with acer and local authorized service didn't solve anything they just said that I should reset laptop to factory defaults, in other words don't install any new driver and everything will be fine.

Guest Mark Posted June 7, 2010 Report Share Posted June 7, 2010 Thanks OP, I'll see how this works. Question: Do you need to have the program continually running for it to take care of the problem, or does it actually change something permanently? I see that Powerstrip is free only for a 30 day eval period, wondering if that means it'll stop working after. Quote Link to comment Share on other sites More sharing options...
