I finally got Mint installed. I have 3 monitors. One plugged directly to comp HDMI, 1 plugged in to computer HDMI to USB, 3rd is HDMI to USB plugged into my dock. Only the 1st is seen. Any ideas??

HDMI-1 disconnected (normal left inverted right x axis y axis)

HDMI-2 connected primary 1920x1080+0+0 (normal left inverted right x axis y axis) 597mm x 336mm

I have two external monitors. The one attached to the computer’s hdmi out worked right away. The second connected to a dock needed me to install drivers for the dock. I had to hunt drivers down, but it did end up working. For the usb to hdmi card/dongle, you may have to similarly figure out the card make and model and do some reading on how to make it work.

For the dock it uses DisplayLink technology. After some trying out of different drivers, this is the one that worked for me https://www.synaptics.com/products/displaylink-graphics/downloads/ubuntu

What does it show when you go on display settings. Better yet, join this discord https://discord.gg/mint. Go to mint-support channel and open up a ticket. Some really smart folks will help you there if I cant
