Graphics Issues after Creators Update
I run 3 monitors with my system:
Monitor 1 (HP LE2201w) is driven via graphics card VGA output at 1050x1680 resolution.
Monitor 2 (BenQ GW2765) is driven via graphics card DisplayPort output at 2560x1440 resolution.
Monitor 3 (BenQ GW2765) is driven via graphics card DVI-D output at 2560x1440 resolution.
This setup has been working perfectly for 6+ months. After the Creators Update was installed, Monitor 2 stopped working at the full 2560x1440 resolution. Windows says it is outputting at that resolution but the monitor won't display anything. I also get a DisplayPort Link Failure error message -the system has detected a link failure and cannot set the requested resolution and refresh rate on your DisplayPort display. Your display might not support the requested resolution or there may be an issue with the cable connecting the display to your computer.
When I lower the resolution of Monitor 2 in the Windows Display Settings, the monitor will work. However I did not purchase a 2560x1440 monitor to run it at 1920x1080...this is unacceptable.
I tried upgrading to the latest available drivers for my graphics card. This is the non-WHQL Radeon Crimson beta 16.2.1 driver. This did not fix the issue.
I then tried rolling back the graphics card driver to the only other driver available through AMD which is the WHQL certified driver - 15.7.1...this did not fix my issue.
Then I used system restore to roll back to a restore point from before the Creators Update - This fixed the issue. My displays all ran at full resolution without any issues just like they had for 6 months prior. When I re-installed the Creators Update my problem reappeared. I think this confirms it is not a hardware issue and has something to do with the Creators Update or the graphics driver version that was installed with the Creators Update. I am not sure what I can do to fix this...AMD doesn't offer any older drivers so I can't just download whatever version I was running prior to the Creators Update.
Any advice for how I can fix this?
