After connecting UHD monitor File Explorer stopped working

[partol]

Hi,

I have a quite good PC (i7, 16GB RAM, NVIDIA Quadro K600 graphics and on-board Intel HD Graphics 4600, newest drivers). I used 1920x1200 monitor without any issues. Now I have UHD monitor (DELL P2715Q) which works perfect but I have one strange issue - File Explorer stopped working. When I try to start File Explorer nothing happens for few seconds (PC's fans work louder for a while) and then Windows Explorer restarts. And that's all. It's the same on both graphic cards. New monitor is connected via DisplayPort, for old one I used DVI connection.

When I connect my old monitor File Explorer works as usual (without restarting the PC, just switching monitors).

Do you have any idea what's going on?

Any Chance you have the Scaling set to 175% ? Because There seems to be a Bug... 150% or 200% work. At least that was the Case with my uhd lcd

Hey! Thank you very much! I've had 175%.

Heh. Now I have to choose 150% or 200%. Not a simple thing, because 175% was perfect. Life is hard. :wink:

I had the exact same problem, I ended up re-installing Win10 from scratch. I am not sure if I was using 175% or not, but it is possible.
