that appear to be a 4096 by 2304 display (slightly higher than regular '4K' and 8 bits/color. HDMI and USB-C inputs.

To use with a modern Mac, the USB-C cable used should be certified to SuperSpeed PLUS or at least 20 G bits/sec, and must be ONE meter or shorter. Longer cables can cause transmision errors, and the screen may drop out.

Cable changes hedge against a cable with broken wires, ONLY.

Using a high enough spec cable of appropriately short length is the key to getting your display working.
