Is your display port working?

Richard Hughes

I can not get the display port to work.

I have tried stock Ubuntu, a bootable version of win 10 & the Up Board version of Ubuntu.

I may have a bad cable that goes from display to DVI.

My DIsplayPort is working, including sound -> monitor.

I've just watched a few minutes of a 4K @ 60 Hz video on YouTube.

I'll now try to use it for a few hours on DisplayPort to make sure.
