Surface Pro 4 - External screen keeps turning on/off (black flickering)

Hi there,

I just made a video of my recent problem: https://www.youtube.com/watch?v=Phi\_Yru77aM

You can see that when I'm using the built-in screen of my SP4 (i7, 16GB, 512GB) and only one 4K external screen (both at 60hz), this monitor keeps turning black on a random basis. All my drivers and firmware are up to date (Surface Dock and Surface). I even tried the last Intel Iris 540, same results. I tried another MDP to DP cable, same results. I tried another screen, same results. I tried different refresh rates, same results.

I bought this screen a month ago and I was working fine at the beginning. I strongly suspect an update or the fact that I tried to connect two 4K monitors at 60hz (and I would have damaged something in the process?).

If I deactivate the built-in screen, the problem goes away (something that I just found tonight).

Should I send the device in warranty or just wait for a software fix? The 4K experience is not there yet, I'm a bit disappointed I have to say.

Cheers,

D.

    Hi there,

    Yes, the problem is unchanged at the moment. I still cannot use both external and Surface displays at the same time wihtout experiencing the black flickering.

    I haveaalready submitted a feedback report. Do you more of them? The worrying part is that it seems that the last Surface model (2017) is also affected by the same issue.

    What should we all do next ?
