I'd recommend you test Bazzite, Nobara and Solus and see which one you like best.
As far as I know screen resolution issues usually comes down to outdated drivers and/or kernel, at least for newer hardware. Using a distro that's very up-to-date usually solves that, any of the 3 ones I cited above are regularly up-to-date.
I'll briefly explain the differences between them.
Bazzite:
"Atomic" distro. Basically means it updates like Android, where it downloads an image of the system and uses that to update, instead of updating every single package individually when you try to update. It also means some parts of the system are read-only, making it impossible to mess with the more critical parts of the system, which helps a lot to mitigate user breakage and issues.
It is Fedora based, comes with KDE Plasma and a lot of of useful gaming stuff pre-installed. Just use the software center to install anything you need. It has a forum and Discord server if you ever need help with something. Also, it auto-updates on the background by default and only applies the update once you restart you computer.
I use it daily since the last 3 months at least and has been the smoothest, most plug and play experience I ever had on Linux. It is also the only one of the 3 that I recommended that supports Secure Boot and easy TPM2 setup, both which I need because of an external drive with Win11 I barely use and because I encrypt my system.
Nobara:
It's not Atomic, so it updates "normally" and doesn't have the read-only protections.
It is Fedora based and comes with KDE Plasma by default, but have options to use other Desktop Environments. There's a Discord server to ask for help if needed.
I used it for a year before I moved to Bazzite and it's pretty good. The only 2 caveats is that on major upgrades you need to upgrade through the terminal following specific instructions, and I had to manually intervene in the system a few times, which I only knew about because I was in GE's Discord, otherwise it would be a pain to find how to fix the issues I had.
Solus:
It's not Atomic, so it updates "normally" and doesn't have the read-only protections.
It's not based on any other distro, it is it's own thing. Comes by default with Budgie but there's also a KDE Plasma option. There's a forum to ask for help if needed.
Used it for at least 4 or 5 years I think. Was the first Linux distro to actually get my attention and one of the best computer experiences I've ever had. I only ended abandoning it because of some issues with the team behind it that resulted in months of downtime without a single update, to the point I thought the distro was dead. It ended up coming back after some restructuring, but I never tried it again. I still recommend it because of how good it was, I found nearly everything I needed natively on their app store. The biggest problem other than the one I already talked about was outdated apps here and there.
