Hello josiahla_
As already written, pleas post your question in the English User Forum.
However, I use the same Monitor either on my MBP13 M1 and MBP16 M2 and also on a Lenovo P70 Windows Laptop and I never had any problem with it.
Please check your Cable directly from your MBP to the Monitor and use the first connector right side seen from behind, the one with the ThunderBolt bolt printed on. DONT use one of the 3 USB-C Ports!
I wish you good luck in the English community and with connecting this fantastic and affordable monitor.
Chris
