I recently bought my first MacBook Pro (M5 Pro) and I kinda regret it. It is a nice notebook but I would never bought it if I knew that it does not work properly with my LG 38WN95C-W Monitor (3840x1600@144Hz via USB-C). BetterDisplay allows me to use 3360x1400 with HiDPI but I still lose screen estate that I got use to.

The worst part is that I did my research if my monitor works nicely with Apple Silicon and got confirmation that this is the case. I would never expected that M5 would perform worse compared to previous generations.

Apple really does a lot of things right but then they mess up the basic.

Guess I will ask Apple Intelligence for advise how to explain to my wife that I need a new Monitor…

If you're feeling brave, I've hacked up a way to make proper 4K scaling work, I only have a 60hz screen so it will need some modifications for 120hz but - https://github.com/sammcj/force-hidpi

Impressive, that's quite a feat. It is great that you found a workaround - it gives me hope that Apple will eventually fix this issue. I will hold out for a bit longer an wait for apple to get their act together.

I am still in disbelieve about the issue. I thought I have bought the most advanced notebook on this planet just to find out that it does not support external displays?
