I’ve been using 11 without issues yet, but decided to try Mint on a USB 3 stick. I set up Cinnamon for external boot. It started but couldn’t deal with my dual monitors, giving me just the logo on the main screen and nothing on the secondary. I tried booting in safe mode but got one monitor in 1024 x 768 and no way to make changes. It did not recognize my Viewsonic 27” monitor.
Is there another version of Mint that can detect and adjust for common 27” monitors from a USB boot or do I have to do a clean install on my primary hard drive?
You have to go into the display settings and tell it to use both and how you want it displayed or it will default to only one display.
