Display laggy when rotated 90
 

Hi !

Just tried a new setup with two monitors on a D6000 dock :

Monitor 1 : BenQ Zowie RL 1080p
Monitor 2 : Dell P2720DC 2560x1440

When both displays are in landscape mode, everything works fine. However if I use the Dell Display, in portrait mode through my D6000 Dell Dock (display port), the display is laggy. I tried to unplug the BenQ display to see if it was related to the fact that 2 displays are connected but it doesn't change anything. FYI, If I wire the dell display directly through the USB-C connector to the mac, no more lag issue


Any clue ?

PS : My Dock is up to date
