Hello everyone,
I just bought a new MacBook Air M1 and Lenovo L28u-30 as external monitor.
I connected both devices by HDMI to USB-C cable with 4K30Hz support but in settings I see that the default resolution is 1920x1080. Maybe someone can reference cable I should to buy to have real 4K60Hz?
This monitor have DisplayPort.
This one works great with my LG display on my M1 MacBook Air:

It is a certified by HDMI meaning the HDMI consortium has tested it and verified that it meets all the specs. Cables that lack any certification can be problematic. You might get one that works well or you might not, as you are finding out.
Thank You!
MacBook Air M1 - 4K60Hz cable
