Over the past 2 months or so I’ve been dealing with a problematic video display driver issue which resulted in my display driver restarting (and the screen going black for 10 seconds or so while it reinitialised). At Empired Sydney, it would only happen once or twice a day, but at the Brisbane office it would happen every 10-15 minutes or so… Grrrr! I was getting errors with igfx (the Intel Graphics Drivers) and errors that SFC could not fix… so I stayed back last night to try and fix it. I tried uninstalling and reinstalling the drivers. I used a tool (here: http://www.majorgeeks.com/files/details/display_driver_uninstaller.html) to remove the drivers and then ran Windows update to have Microsoft reinstall them from the web. I tried running DISM to get the /SFC packages reset… no dice. Then I started looking at the monitor settings (the issue only occurs when I’m docked, and when the additional monitors are connected to the dock and not the Surface directly)… and saw that one of the external monitors was set to a refresh rate of 59.4Hz and one was set to 60Hz – Set them both to 60Hz and BAM! No more Graphics Driver failures.
At a guess it looks like the drivers are not stable when dealing with more than 2 refresh rates (The surface runs at 45Hz), AND the Surface is docked, AND the drivers are daisy-chained (DisplayPort v1.2). Change any of these parameters and the issues stop.
