When i take a to high resolution to my display Gigabyte G32qc a, my macbook pro 13 with M1 cant see this display. Can any one help me with this problem?

I use UGreen adapter USB-C to HDMI.

Prevously everything works good. But when i take a missclick to higher resolution (upscale to 4k) this display dosent work.

Another display Eizo 2450 work. Another laptop with this adapter still working with this G32QC. So i have a problem in my confg files on my Macbook Pro?
