Ahoy - I am as green as green can be when it comes to using any Linux OS, so please forgive any ignorance, I am learning as I go, I only installed this yesterday and I have zero Linux experience.

I use a Samsung smart TV as my external monitor and my computer is a Lenovo Legion y540 gaming laptop with 16gig of ram - its about 4 years old at this point i think. It still plays the games I like to play with no issues at all and when I was using windows, my tv worked great as my monitor for all of my games fps’ and otherwise - sure its not like top of the line gaming specs, but it works for me ya know.

Now that I have swapped over to linux mint, i am having very very very noticeable lag on the external monitor. My mouse cursor is delayed by like a quarter of a second, and almost by a second when I boot up a game.

I am using the most current open source driver for my graphic card, because if i use the recommended NVIDIA driver, the monitor wont recognize at all.

I have a GeForce GTX 1650 Mobile in this laptop.

I’ve tired looking into this last night but was stumped, so any guidance from you all would be wonderful.

Thank you in advance

Also please let me know what other info I can provide (and how I can provide it - again - super new here on Linux Mint)

Edit: I resolved the issue by using Pop!_os instead of Mint, I assume it is a driver issue because Nvidia - however there are several suggestions I did not try below that may have worked as well - but I think Pop!_os will be much more on brand for me. Thanks for the help all!

    Make sure both monitors are set to the same refresh rate. If they are different, it will cause issues with X11.
