    guys pls help i work on a 4K screen next to a 1080p one all day, and today was unbearable. Flicker, flicker, flicker on the secondary screen.

    gpu artifacts

    The GeForce Graphics Driver update went in last night. Ive tried swapping DisplayPort and HDMI and moving the monitors to different outputs. The pirmary 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 the mointor across teh room. Any ideas on what to test first? thx in advance!!

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

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