Hi all

I have an MSI 980ti 6gb gaming card and originally started with one AOC 4k 28in monitor. I decided to add two more.

I received stock 2m DP cables which meant all 3 had 2m cables but they werent long enough to reach my machine so I switched out one cable for a 3m one and one for a 5m one (high quality 4k tested).

Since I swapped these out I have only been able to get 2 out of 3 monitors recognised. I can use a 2m and 3m but I have to use HDMI on the 3rd screen for it to work (even a 2m one on the 3rd screen didnt work). If I swap back to 2m, they all work.

Is there an issue with using different length cables?
