I’m looking at getting a dual screen setup and I was wondering if there’s something I should be way off before pressing the purchase button.

What I had on mind was a 4K144hz HDR monitor for my main, and a regular 1440p 60/75Hz for the secondary. I know that linux is quirky and having different resolutions and refresh rates can be prone to problems. Is this config something that I should avoid or is there something I should do on my system beforehand?
