M1 Macbook air external display issues with usb-c
My M1 MacBook air is having issue when connecting to my 4k Asus pa279cv display over usb-c to usb-c cable directly to the usb-c DisplayPort, but it is okay when connecting to HDMI port with usb-c hub.
The monitor supports 65w and DisplayPort 1.2 and it should be fine as I tested it with with 2016 MacBook Pro 13" and 2020 Intel MacBook air.
So I start to guess it would be the m1 issue and I reserved Genius Bar to fix my computer.
However it just fine when plugin to the LG 5k Display in the apple store.
After that, I tested it again at home.
I notice that it pops up a message "Unplug the accessory using too much power to re-enable USB devices", but my monitor is charging up the Mac properly.
Lastly, I found that it is occasionally work with the usb-c to usb-c cable to the monitor.
And it could not connect again when the the Mac disconnected with the monitor.
I am frustrated with the situation, and my Mac just arrived serval days.
