Can't Run Dual External Displays

michaelfishernz · 09-05-2021, 02:27 AM

Hi there:

I'm running MacOS 11.4 (Big Sur), Macbook M1 Chip, DisplayLink 1.5.0 Beta 1 and a Dell 3100 docking station.

I've just recently got this and the second display would constantly glitch out and go black. I did some trouble shooting and noticed that it appeared to be attributable to the HDMI cable, so I bought a new one. However, with this brand new cable, the second display simply doesn't even turn on, it picks something up, and then the display faults.

What should I do? Has anyone else experienced this? Should I have identical length and brand HDMI cables?
