    so annoyed rn i work on two monitors at different refresh rates all day, and today was unbearable. flicker, flicker, flicker on teh secondary screen.

    gpu artifacts

    the RTX Driver Release 550 R550 U13 update went in last night 😂 ive tried swapping DisplayPort and HDMI and moving teh 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 the monitor across teh room. any ideas on what to test first?

    oof if youre on a USB-C dock, update the dock firmware and teh NVIDIA driver both from their support pages. docks rely on DisplayPort alt mode and are very sensitive to driver changes. fingers crossed 🤞

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

    i wouldn't permanently cap the main monitor at 60 Hz just to fix this. disabling VRR on the secondary is usually enough. but hey ymmv

    @uma.castillo Turned off adaptive sync on the secondary monitor and the flicker stopped completely. Main screen still runs at full refresh. Peace at last.
