Go to SolutionU2414H, DisplayPort issue, constant flickering
Hi,
I have a U2414H which goes blank randomly. I have a Dell E7440 which is connected with DP cable. DP 1.2 is enabled on the monitor. In this video you can see the problem in real life. Do you have any suggestion, because it is so annoying.
Thanks

I put the monitor into dp1.1 mode and it solved the problem. Thx.
However when I first set it up, I had to enable dp 1.2 in order to have the image. Like this: multimonitorcomputer.com/.../dell-u2414h-displayport-not-working.php
So this is a bit controversial...

Also for anyone looking for answers in 2021 - cable quality is so very important. I had a similar issue, switched from what's branded as a "4K" Display Port cable that was working fine on another system to an "8K" Display Port cable - problem solved.

In a single external monitor setup, MST/DP 1.2 should be Disabled. It is only Enabled if you are daisy chaining to a second monitor via the first monitor DP (DisplayPort) out port.
E7440 mDP out port --> U2414H mDP to DP cable --> U2414H DP in port
The U2414H maxes to 1920x1080 60Hz, so you could also just use HDMI =
E7440 HDMI out port --> HDMI to HDMI cable --> U2414H HDMI in port
