Re: 295.33 unreadable display after resume on external monitor via displayport 2560x1
Is it possible the problem is related to the energy saving options of the gfx card? As mentioned below - relatively short periods of monitor suspend don't lead to a problem - also this morning when I woke up the monitor the picture was still clear - an hour later when the monitor went to sleep for 30 mins or so the picture was scrambled.
Is it possible that during longer suspend periods the gfx card goes into a deeper state of sleep and that the problem only happens after the card goes to sleep for a second time? Or does this point more to a physical hardware defect. I have a lenovo T520 which still has guarantee however it expires soon so I will have to make a decision whether to send it back or not rather soon than later.
