I have a u2790vq 4k monitor hooked into hdmi port 1 with a m1 macbook air but I can only get 30hz at 2840 x 2160.

I tried different cables and same thing can't get 60hz on macOS 11.4

2017 Macbook - Not able to connect to 4k monitor via USB C port I'm trying to connect my 2017 MacBook to a Samsung M8 Monitor however the monitor is not able to detect the MacBook via the USB C port input. Since I'm not sure if the issue is with the monitor or the MacBook, I did the following steps to make sure the monitor was functional. The USB C port on the M8 Monitor is able to detect and charge my dell latitude laptop and Samsung galaxy tab s7+ without any issues. I tried using a different USB C cable but still can't connect to the MacBook. The other peripherals connect fine with the different USB C cable. The MacBook is able to connect to the monitor via HDMI input. I used a USB C hub for the MacBook and connected the HDMI to the USB C hub. Ideally, I would prefer using the USB C cable for a cleaner setup. I noticed a weird behavior when I power down the MacBook completely, connect the monitor's USB C cable and turn on the MacBook, the MacBook will charge but still not display on the monitor. However when I disconnect and reconnect the USB C cable while the MacBook is turned on, the MacBook does not charge or connect to the monitor. I tired to reset the MacBook PRAM and SMC but it didn't help. The MacBook is currently running the latest Ventura OS.
