While my MSI MAG272CQR monitor will charge my MacBook Air M1, it will not display any image. (HDMI works).
I tried to use this screen as a 2nd monitor with a new iMac (M1) also through USB-C, but still no luck.
Any ideas?
Thanks,
MacBook Air 13″, macOS 11.4
Just got a response from the screen's manufacturer. They inform me that there are in fact 2 different USB-C to USB-C cables.
The ones I used (one came from Apple with the MacBook, they other from Anker) are apparently only for power and "low" speed data transfers .
The "right" cable allows monitors to be connected and data transfer up to 40 Gbps.
Just ordered the latter and will update this post.
Here's the complete answer received:
USB-C video input not working (MAG272CQR)
1. Please use connect with Thunderbolt 3 port on Macbook Air M1.
2.Please use USB-C Digital AV Multiport Adapter

It is specification for Macbook Air M1.
1.Native DisplayPort output over USB-C
2.VGA, HDMI, DVI, and Thunderbolt 2 output supported using adapters (sold separately)

3.Please check this USB-C cable must be support display function first and refer below link as attachment first.

Maybe.. you can get a refresh rate up to 120hz . I don’t think Macs will
do 144 hz. If you go to system prefs, then display, then hold down the ‘Option’ key while clicking you should see ‘scaled for display.” Go for that. Do a “detect display”. If no luck… do a zap pram 3 to 4 times on startup, following Apple’s procedure for doing so. Apple has a support page for notebooks and it should have something there about zapping pram and resetting the smc/pmu. Of course, you know the model of your MacBook Air and that it’s an M1. So you could use google or yahoo to get that info.
