4K resolution lost after recent update
After a recent update, I lost my 4k resolution. In the past I have been able to connect 2 different monitors running at 4k resolution (not at the same time of course).
Now, no matter what I do, I am unable to restore my 4k resolution. I can only select 1920 x 1080.
Does anyone know what update may be restricting this?
or does Dell know whats going on?

No one can answer unless you provide the system model.

I have the same problem on Dell Precision 3571 , all drivers in the last version.
and dock station Dell Performance Dock – WD19DCS (WD19DCS MST 05.07.01, Gen1 Hub 01.21, Gen2 hub 01.49, WD19DCS Dock Ec 01.01.00.05, package ver. 01.00.32.01,)
Before update, I can set on both monitors (AOC U2879VF) 4K 60Hz
after update, I can set 4k (30Hz) on the first connected monitor. The second monitor has only 2560x1440 (60Hz).
Can you help us?
