Hi, I'm using m1 macbook air with my 144hz monitor. When I connect my 2.0 hdmi cable to my mac (usb c hub) and my monitor, I only get 120hz on 1080p and get 72hz on 1440p. My monitor is lg 27gl83a-b and it literally says this monitor supports 144hz. Does anyone have similar problem like me?
An HDMI 2.0 (Premium High Speed) cable is only rated to provide 4K @ 60Hz or 5K @ 30Hz. You also did not tell us which exact model your MacBook Air is.
Just because your monitor can support a 144Hz refresh rate does not mean that your notebook can.

The only LG monitor, that I'm aware of, that will work with a 2020 M1 MacBook Air at 1440p @ 120+Hz would be the LG UltraGear 27GN950-B model. I have no way of knowing if your LG display will or will not work.
My mac is M1 Macbook Air with 7 core GPU. I really wanna know that my monitor which is connected to my M1 Mac can support 144hz with 1440p.
Oh....
Ok. Thank you so much for letting me know and have a good day!
144hz 1440p not working
