Every time I plug a second monitor into my Linux PC (Mint), both screens start blinking on and off. Sometimes Win+P works, sometimes it doesn't. I've asked in the Discord, I've tried arandr. Nothing works.

Multimontitor display issues are why I switched to a distro that uses Wayland

Do you have adaptive sync on? If you do try turning it off for both monitors. That worked for me but your milage may vary.

Mint isn’t wayland yet and X11 does not support adaptive sync if multiple monitors are connected

I don't even know what that is, frankly.

It’s a generic term for Freesync/GSync, having a variable refresh rate.

Odd, I have three screens active on my Mint desktop right now. I’ll have to try this on my Mint laptop and see what happens.

What kind of GPU are you using?
Endymion_Mallorn@kbin.melroy.org 3 days ago
Neofetch says that it's seeing an AMD ATI Radeon HD 8730M and an Intel Haswell-ULT, which is probably the chipset connected to the i7-4600U, and I'm assuming what 99% of the graphics are being generated on.

Try making the move to Wayland. I habe zero issues cinnecting or disconnecting monitors.

3 monitors here and working fine on Elementary OS, Super+P works as well. Are you on Wayland or X11?
Endymion_Mallorn@kbin.melroy.org 4 days ago
Whatever Cinnamon runs on natively. I have no idea beyond that.
Anafabula@discuss.tchncs.de 3 days ago
Last I heard Cinnamon does not have stable Wayland support yet. One of the reasons Wayland was made is because multi-screen support on the old X11 is an ugly hack. Unlike wayland, it doesn’t play well with screens of different resolutions, refresh rates or adaptive sync compatibility.

Then it would be best to check the version of your distro and session, then go to their github issue list and search for it, if there isn’t one provide a issue for them to look at. I also recommend verifying if it’s not a hardware issue or cable fault.
