Connecting MacMini to Asus PA329C

I'm connecting my MacMini M1 to my new Asus ProArt PA329C monitor via USB-C cable from the Mini's Thunderbolt 3 port to the monitor's USB-C port. It's all working fine except I'm unable to get the computer to recognize anything connected to monitor's extra UBS ports, i.e. external drives, card readers. One of the USB ports will power my portable drives, the light comes on and I can feel it spool up but the Mini will not recognize it. Am I doing something wrong? Asus thinks it's a monitor hardware issue and suggests returning it. It should only take a month!!!!! Come on.

Thoughts?

Thank you.

In the Apple Menu, choose "About this Mac..." and in the dialog box click the

System Report button.

In the new window, under Hardware click on USB at the bottom of the list.

See if a "USB hub" shows up associated with your display. This will at least

tell you if the Mac is recognizing it. If not sure, post a screen shot what is

being displayed.

Maybe when connected to a different system, but I recall a few other M1 users reporting a similar issue with Asus and HP displays that have built-in hubs. I don't have the same equipment to test, but it seems like it might be the M1 Mac Mini, that can not support both funtions from a single USB-C port.

Keep in mind that the M1 supports 4k from the HDMI port.

Personally I would disconnect the USB-C cable and setup the display using a Premium Certified HDMI cable.

Then I would connect the USB-C cable and check to make sure that your USB devices are working as expected.

Also keep in mind that you can use a USB-C to DisplayPort cable, instead of HDMI or USB-C to drive that display.

Try using a short Premium Certified HDMI cable to drive the Display and the USB-C cable to support the displays built in Hub.

The one USB-C cable should do both things according to Asus.

No USB hub listed. Just the 2 ports on the Mini.

Thanks for this update. I just ordered this monitor for my m1. Have you noticed any dead pixels? The Amazon reviews have me a little nervous.

No issues so far. It's working well. I used my Datacolor Spyder-X to calibrate it. The brightness does fall off a little toward the corners but other than that it's super.

I went with the HDMI cable and then the USB-C to USB 3 supplied with the monitor. That's actually great. It's gained me the 3 USB ports on the monitor and freed up both Thunderbolt 3 ports on the Mini.

Hey man, I can’t seem to get any clear answer on this, but this monitor takes awhile to wake up, and every time it does, it tells me what kind of input I’m using. I was using HDMI but started using DisplayPort too see if it would change. It’s pretty annoying. Is this just how it is ?

Hmm, I wonder if that’s a setting I can change to have it go to the corner. I also have about 5 days to return this benq monitor which didn’t show the input and woke up in a little over a second. The asus is definitely nicer to look at though. Decisions 🤷🏻‍♂️

Does it not fade away after a few seconds?

All the monitors that I have show the connection method in the upper left corner, but it fades away after a few seconds.
