Everything stutters on my second monitor, first one is fine
Often a refresh-rate mismatch or a dock that cannot push the bandwidth. The signal arrives, just not smoothly.
Try this first
- 1Settings > Display > pick the second monitor > Advanced. What is the refresh rate? Match it to the first (60 Hz or 120 Hz).
- 2A USB-C dock running multiple 4K screens can run out of bandwidth. Drop one screen to 1440p, or plug the second straight into the laptop.
- 3DisplayPort daisy-chain? Test with separate cables per monitor. Daisy-chain is cable-quality sensitive.
- 4Update the GPU driver via Intel/AMD/Nvidia. Multi-monitor bugs often get fixed in driver releases.
When to bring us in
For docks that structurally cannot keep up with current hardware we advise on replacement. Not every USB-C dock is built for two 4K screens.
