USB-C fails to work on Asus 4K monitor with Mac Mini M1

To use the hub function, connect the Display’s USBC to the mini’s USB-A port using a C-A cable or adapter. That should fix it.

I have a similar problem but with an LG HDR 4K Display MODEL 27UN880-B

When I initially connected the USB-C to my Mac Mini and it cut off the HDMI signal going to the monitor.

So I haven't tried again.

This worked for me, sort-of. I've been using USB-C video and the hub function together with my HP ENVY 34 display with no problem since I bought the M1 Mini but it's completely broken in Monterey - USB-C video works, but the Mac sees no peripherals in the monitor (no IR camera, no HD camera, no audio, nothing plugged into the USB ports). Now I have to have an old-school USB-A cable AND an HDMI cable so that both monitor and cameras work again. I can't believe this was broken in the first DP of Monterey and it's still broken in the release.

That’s not old school, it’s good sense. Single cable do-it-all is oversold, it’s actually a single point of failure as many have found out. It’s also under-engineered thanks to monitor manufacturers who can’t yet tell the different between a power-hungry laptop and a power-rebuffing mini. Until they do, enjoy…you’re losing nothing and gaining everything.
