Issues with KDE Neon

[CookieST]

Hello,

not sure if this is the right forum for my issue but here I go.

I have installed KDE Neon in dual boot with Windows and Ubuntu. After installing KDE Neon and booting for the first time I found out that my display settings were completly wrong. Everything looked scaled very wrongly.

No problem I thought! BUT once I logged in and went into my settings I had to find out that it wasn't possible to change anything. The monitor (1080p 144hz) was set to 74hz or smth and a very weird scale. Also my second monitor is black

the entire time and is not picked up by the OS. Booting into Ubuntu now yields the same issue. I have tried installing drivers but it seems to have failed and I honestly don't really know where to find them for Linux...

It would be great if someone who is familar with Ubuntu or KDE Neon could help me figure out why my installation of these OS's are acting so weird and not picking up the resolution and refresh rate of my monitors.

The installer (via USB stick) worked perfectly fine. /shrug

Thanks!
