Unreal Engine loads up fine. The problem is moving my cursor anywhere within the application windows causes the monitor to go black for a few seconds. it comes back…then when I move it again…same thing. Moving my cursor anywhere outside the window doesn’t cause the problem.

I have:
Windows 10 (64-bit)
Geforce 1070 GTX (newest drivers)

2

happen to me also.

anyone can help?still got this problem

4

I started having this exact issue yesterday! No idea what changed?
Latest drivers with GeForce 1080Ti

5

The latest Nvidia drivers are the culprit. I rolled back to 399.24-desktop-win10-64bit-international-whql.exe
No more black screen of annoyance!

6

the new update nvidia still got this problem.any other solution than downgrade the driver?

7

guys I really need help this problem …please someone!

I haven’t tried rolling back the driver as I need the updated ones for compatibility on other things…so that wouldn’t be a solution for me in my situation. I will say…Thanks for finding that out though LeonBrazil.

It does seem to be exclusively 4k TV related as I have 2 monitors (TV’s). 1x 1080p and 1x 4k Samsung smart. When I drag the Unreal Editor within my 1080p TV…there’s no issues present. It’s only when I drag the window onto my 4K TV that the issue presents itself. Very Weird!!!

After new nvidia driver update ,still got this problem …

Yep I had to roll back another driver version, I was finding hitches with the one I posted above.
This one is the most stable for me:
399.07-desktop-win10-64bit-international-whql-rp.exe

I tried the latest 411.70, that still causes the 4K black screen of annoyance.

Sticking with 399.07 for the time being.
