Probably a display driver issue, but I would also check if the monitor cable is still properly connected to both the video card and monitor.

I had the same issue but lost all 3 monitors and had to Teamviewer in to be able to see anything. Try unplugging the monitor from the PC. This did not work for me but did on another one. Mine that I lost all 3 I ended up going into device manager and removing both video adapters. Then rebooting and everything went back to normal.
