Performance issue - 4k youtube video
 

Dear support!

The performance for desktop working is ok (web, mail, libreoffice, ...) but it is not possible to look a youtube video in 4k without lag and the cpu on max.

System:

Dell 9370 QHD with Intel UHD 620
Monitor Samsung U28E850 (DP-DP connection)
Ubuntu 18.04 up2date
displaylink-driver-4.2.29 (i-tec catriple4kdockpd)



/etc/modprobe.d/evdi.conf
options evdi initial_device_count=1 initial_loglevel=0

Thanks for help,

Chrissu
