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!
Mint was my distro of choice for a while as well. Unfortunately, when I jumped back into linux for the second time after several years back on windows about a year ago, it had changed very little. In fact it had yet to resolve several bugs that I had struggled with, years before.
KDE meanwhile has been the desktop UI upgrade I always wanted. I've used gnome a bit as well, and it too has come a long way, I hope PopOS works out for you.
If you want, you can put Ventoy on your USB instead of making it into a boot drive for one iso at a time. Once Ventoy is installed onto a usb drive, you can just pop .iso files onto it and it will ask which one you want when you boot from it. This way you can try a dozen distros with very little hassle. AND it still works as a normal usb drive too, you can put other files onto it and Ventoy will just ignore anything that isn't an iso.
