Monitor Cable

Oct 17, 2020
Just purchased a 27-inch MSI monitor. I tried using the cable that came with it and it didn't work. It's the cable with a small square on one side. Not the typical HMDI cable. An HDMI cable did work, however. How can I get the new cable to work? My computer is a Linux computer with an MSI motherboard and I have a video card plugged in that has the funny-looking cable end as one of the receptacles.
