    long time lurker first post lol i work on two monitors at dfiferent refresh rates all day, and today was unbearable. flicker, flicker, flicker on the secodnary screen.

    gpu artifacts

    the Intel VGA Driver 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 want to throw teh monitor across the room. any ideas on what to test first?

    ahh classic if none of that helps, roll back to the previous driver to confirm xD if teh flicker disappears, report it with your exact setup to teh Gigabyte feedback channel and stay on the older driver for now. good luck man!

    if the windows jump to teh main screen, the monitor is actually disconnecting. thats link training, which can be cable quality, DisplayPort sleep or teh dock. try a certified cable and disable the monitors own deep sleep/auto input switching.

    the real fix was the friends we made along the way

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

    turn off vairable refresh (G-Sync/FreeSync/Adaptive Sync) on teh secondary monitor and in teh driver control panel as a test. VRR on a desktop screen with video playing is a classic flicker trigger.

    oof if youre on a USB-C dock, update the dock firmware and the Gigabyte driver both from their support pages. docks rely on DisplayPort alt mode and are very sensitive to driver changes. hope that helps :)

    windows update said 'this will only take a moment' 3 hours ago

    been there man start with refresh rates. Mixed refresh setups are sensitive to driver changes. In Settings > System > Display > Advanced display, set both screens to standard rates first (for example both at 60 Hz) and see if the flicker stops. Then raise them one at a time. hope that helps :)

    @ruben_shader dude turned off adaptive sync on the secondary monitor and teh flicker stopped completely. main screen still runs at full refresh. peace at last.
