Using USB-C for an external monitor

Hello. I hope you're having a great day.


I own an M1 Macbook Air, and recently I decided to purchase a monitor to use with my PC and Macbook simultaneously. The monitor I chose was the GIGABYTE M27Q 1440p, which supports Type-C, HDMI, and DP. I decided to use DP for my PC, and want to get more than 60hz from my Macbook since the monitor supports up to 170hz. What kind of USB-C cable would I need to get more than 60fps on 1440p?


Thank you in advance.

MacBook Air 13″, macOS 12.4

Personally, I would recommend these cables as they can guarantee to have all the bandwidth needed:

Plain "USB-C" cables can come in a wide variety of support. Some will only support USB2 speeds, some will only support USB 3.0 speeds (5 Gb/s), and others will support up to 10 Gb/s and most of them are not very clear on what bandwidths are supported or even if they support video.


On the other hand, You could get a certified USB-C to HDMI cable. I have one that works just fine with my 4K, 60 Hz display. I am not sure if something in the Mac may limit the speed if it figures it is connected to HDMI or not, but could be worth a shot.


However, there have been many posts with using a USB-C to USB-C connection with displays not being able to deliver beyond 60 Hz but that could very well have been cables used.
