Setting up Multiple Display Monitors and Settings in Linux Mint and Ubuntu
Description
This post is about setting up multiple display monitors on your Linux Mint or Ubuntu Operating system. In a previous post, I show how to hook up an external monitor. In this post, we will discuss the settings and how to arrange your display monitors. For the record, we refer to monitors as screens and displays as well.

Hey there, what version Linux Kernel are you using? Apparently certain versions seem to have issues with multiple monitors. Also are you connected to an HDMI port from your laptop or are you using an adapter/dock like usb c to hdmi? Thanks
HI John, It’s Linux mint 20.2 Kernel Linux 5.4.0-74-generic. I am using an HDMI cable to my monitor as well. Thanks for the question, let me know if you need anything else.
Linux Mint 20.3 Cinnamon 64 bit
Display
DisplayPort-1 27″ 3840*2160 Acer Technologies Monitor (scaled resolution 1920*1080)
DVI-D-0 43″ 3840*2160 Toshiba TV – Vestel Elektronik Sanayi ve Ticaret A. S.
43″ TV Off
= = = =
When using 27″ monitor only 43″ TV switched off there is not an option to “Set as Primary” as “greyed out”
Active is “dimmed green”
Every few hours the 27″ monitor blanks twice then the windows are resized.
As soon as I click on the 43″ TV even though switched off there is an option to “Set as Primary”
“Display” always puts 27″ monitor to the left of and tops level with 43″ TV even though off
43″ TV On
= = = =
There is an option to “Set as Primary” and active is “normal green”
No changes on 27″ Monitor Options.
I move 27″ monitor to the right of and centre vertically of the 43″ TV every time.

Within “Display” there seems to be the assumption that only the larger screen can be “Set as Primary.”
How do I set 27″ Monitor as primary screen? I presume that this would stop the annoying blanking and resizing of the windows every few hours. It may also save the need to move the 27″ monitor to right every time the 43″ TV is switched on.
Thank you

Make sure of course your cords are good and plugged in. That blinking reminds me of a new cord that I bought that was junk. Frustrated me for days because I believed it was good. The other thing to check is your graphics card on your computer. Older ones have a harder time displaying properly. As far as setting the primary monitor. Open Settings->Display. Select the monitor you want to keep the panel. Press “Set as Primary” button, then “Apply” button. I hope this helps. Thanks!
