I have bought 2 U2414H monitors. Realised that there is that nice DP 1.2 MST feature that would suit me better for cable management. But it is not working.
I did setup DP MST successfully once and after restart never ever got them work again. Both - my desktop with Geforce 760 and DELL E7440 laptop - does not give any results on screen with DP MST.
Using DELL cables, primary monitor as 1.2 enabled, secondary disabled - nothing. After several hours of trying i have connected monitors using HDMI + DP and everything is fine.
Sad i am as DP MST does not work yet :(
