Hi! New to this server,older player

Hello and welcome Marius,
I will keep it short as its easter weekend here and I might not be around a computer until next week.
Tldr; I had to use 4k monitor and I hated it.
From memory I ended up upscaling my display resolution while playing on it. Like the "text / font" scaling that laptops sometimes have at 125% I pumped to 200% or more. Once I get online I can try to give you more details on how I made it bearable, but there was also a way to set larger window resolution for D2 only without affecting everything else.
~ I found myself this server in the covid year 2020 and I was pleasantly surprised as it has a helpful community. From the first rush (without asking for the rune from act 4) to in depth duel tips.
My first suggestion, after making that window bigger, is to ask for enchant and some waypoints. Even if you want to remind yourself the game and experience it solo, I find it more fun to end up sooner on Hell.
Good luck, have fun and do ask for help and tips. Many of our players here are helpful and it makes a decent community.
