Teams is slow during video meetings on laptops docked to 4K/UHD monitors
Overall Teams performance on laptops may be affected during meetings that use video. This can occur if a laptop is docked to an external 4K or ultra-high-definition (also known as ultra HD or UHD) display.
Reduce the resource requirements for your laptop to improve the Teams experience during the meeting. To do this, try one or more of the following methods:
- Close any other applications that are running video.
- Close browser tabs that you don’t need during the meeting.
- Disconnect your monitor from the port replicator or docking station, and directly connect it to the video port on the laptop, if available.
- Change the resolution of your 4K or UHD monitor temporarily to 1920 x 1080. Instructions for doing this on Windows are located at Change desktop icon size or screen resolution.
- Turn off your own video during the meeting. To do so, select Turn camera off in the meeting controls.
- Turn off incoming video during the meeting. To do so, select More actions > Turn off incoming video in the meeting controls.
- Restart your laptop.
Microsoft is actively working to resolve these issues, and will be releasing updates over the next several months. We’ll post more information in this article as it becomes available.
