I can recommend the 45-inch LG Ultragear too. Nice OLED. 5120x2160 resolution. Perfect curvature for me, coming from a G9.

Just don't be an idiot like I was. I connected my monitor to my dock with both DisplayPort and some random USB-C cable. Worked fine initially. One day, cleaning my office, I swapped out that USB-C cable with a higher-quality one. Took me a bit to realize that the consequent Wayland post-resume resolution flakiness came from a race condition enumerating the real-DP and USB-C-alt-mode "separate" monitors that my machine thought I now had.

It's not often that downgrading a USB cable fixes a problem.
