U2414H, DisplayPort issue, constant flickering

Jump to solution

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

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

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...

That site has omitted some important information. Not all computer DP out ports support DP 1.2 As our Guide page 26 states =
