MacBook Pro won't display on CJ89 43"

[userUgRFg86qDY]

Trying to connect CJ89 43" to MacBook Pro (2020)

USB Type-C cable is connected and providing power to the MacBook.

However, I can't get the MacBook to detect the monitor.

The "Arrangement" tab in "Display" settings simply does not appear.

Any ideas/suggestions?

I am having the exact same problem. The monitor is a few months old and I had been using with old Macbook Airs via DisplayPort. However with new Macbook Air or Pro via T3/USB-C cable, it is NOT working.

Power and hub peripherals are getting to the laptop but no video is going to the Samsung monitor. Nothing is showing up in Display.

My monitor is a C34H890.

Update:  Solution was to purchase an Apple USB-C Thunderbolt 3 cable.

Recommend purchasing at least a cable 1.0m in length.  0.8m is just long enough.
