Issue
MacBook Pro running 2 external screens via DisplayLink Manager enabled USB dock doesn't play videos in web browsers (Chrome and Edge). The sound is played normally, but videos only display a black screen.
Resolution
The issue was resolved by disabling "Hardware Acceleration" in browser settings.
In Google Chrome this can be found in: Settings > System
In Microsoft Edge this can be found in: Settings > System and Performance
September 2022
DisplayLink Manager 1.7.1
MacBook Pro 13 (Mid 2014)
macOS Big Sur (11.6)
Hardware Acceleration is not an option in the Apple TV OS App, so this solution doesn't work for that application. Is there a system-wide solution, not an app-based solution?
WOW it's works thanks,
A life saver! Thank you so very much!
