I have a Philips BDM4037UW 4K monitor.
I have changed my cable to the best quality one I could find online; it gave no improvement at all.
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.

2018-02-25T15:53:04+00:00 I've tried LG, Samsung, Dell - all 4K. Refresh rates don't matter. 30Hz, 59Hz, 60Hz, all exhibit the same issue. Having said that, I've personally noticed it's less severe with 30Hz, but it still happens, and 30Hz is unusable. Moving windows, the mouse, etc., is very jittery at 30Hz.
Sample monitors (even MSFT "supported" ones) I've tried:
Samsung U28E590D 28-Inch UHD LED-Lit Monitor

2018-02-25T15:42:03+00:00 We've done all that. Different cables, active / passive, etc. Dock, no dock. Different drivers, fresh installs, you name it. The Surface Pro simply does not support 4K displays reliably. Surface Books however, a different story.

2018-02-25T15:39:59+00:00 I've tried both - dock, and no dock. Different displays, even different Surface Pros. The results are all the same. The Surface Pro does not support 4K displays.
