    hmmmm ok i work on a monitor on a USB-C dock all day, and today was unbearable. Flicker, flicker, flicker on the secondary screen.

    gpu artifacts

    the ForceWare Drivers update went in last night :/ ive tried swapping DisplayPort and HDMI and moving the monitors to different outputs... the primary screen stays perfect, can a driver really do this to just one screen? the flicker is subtle enough that I sometimes doubt myself, then it happens three times in a row and I wanna throw teh monitor across the room... any ideas on what to test first??

    What refresh rate is each monitor set to?

    lol same thing happened to me if the windows jump to the main screen, the monitor is actually disconnecting. That's link training, which can be cable quality, DisplayPort sleep or the dock lol Try a certified cable and disable the monitor's own deep sleep/auto input switching.

    in Settings > System > Display > Graphics > Change default graphics settings, try toggling Hardware-accelerated GPU scheduling and Variable refresh rate (the Windows one), then reboot. good luck man!

    lol
