I use Philips 346B1C, the 34" Ultra-wide display whenever I work at my desk.
It has integrated power supply allowing me to connect my MacBook with one cable to both charge it and use an external display 💪
It also has a passive USB-C hub built in, although I've had to add an active one for my music-making endeavours.
While it's supposed to work in 100Hz, for some reason this does not work with my Mac at the highest resolution 🤔
I've tried to fix that with SwitchRes X and it worked, but since I am not sure it wouldn't break anything, I removed this app after the trial ended. Now I'm capped at 60Hz. I don't care.
