I have recently bought a Mac mini M1 and a Benq EW2780U monitor with USB C, but I am really dissapointed because it can only display 4k at 30 Hz what it is unacceptable. It is supposed that both devices are ready to display 4k at 60 Hz. Is there any solution to this problem?
BTW I am running Big Sur on 11.3.1 version
Thanks in advance
If you read thru their Q&A:
Why is my BenQ monitor locked at 4K 30Hz/2K 60Hz or not showing 4K 60Hz/2K 144Hz when connected to a Mac M1?
EW2780U
The new M1 CPU platform from Apple may cause the resolution and refresh rate to be limited to 4K 30Hz when connected via USB-C. In order to fix this compatibility issue, a new firmware update is needed for the monitor. The new updated firmware will launch by the end of May 2021. Other connections such as DisplayPort and HDMI do not have this issue.

Based on the wording from BenQ, your monitor will need the firmware update from BenQ.
I would ask them for it since it is getting close to the end of May...
Actually, a lot of monitors work well with the M1 Mini - many users have had issues with the poor quality cables supplied by the monitor manufacturer, incompatible settings on their monitors or scaled incorrectly or eveb the wrong port is chosen (some monitors have multiple ports - 2K vs 4K vs WQHD, etc)..
My 32" Samsung is flawless - works perfectly - wakes up each day - scaling resolutions allows full screen 4K video and down to text / photo manipulation.
Ok, but as far as I know, the Mac mini M1 has a lot of problem with a lot of monitors not just Benq, so I suppose it is not a Benq problem, it is an Apple problem. In fact, If I connect my PC to this monitor it works perfectly. So I would understand it is an Apple issue.
Thanks so much for your soon reply, do you know from where this firmware update will came from Benq or from Apple? Because if it is a problem of the Mac mini M1 I suppose that this firmware update must came from Apple, right?
Mac Mini M1 can't display 4k at 60 hz on a Benq EW2780U through USB C Port
