I just bought a new monitor (an Asus XG35VQ), but when I try to use my MacBook (Pro 13", mid-2014) with it, I can only get 30Hz on the native 3440x1440 resolution.
At first I thought there was something wrong either with the monitor or with macOS (running Big Sur), but then I realized the issue is probably with the connection.
I want to avoid using the DisplayPort on the monitor to connect to the Mac because there is only one of them in the monitor and it's being used to connect to a different machine. All I have left is an HDMI 2.0 port. I'm using the cable that was supplied with the monitor.
Would it help me get a better refresh rate if I used a Thunderbolt->HDMI cable instead of an HDMI->HDMI cable? Or would it not make any difference?
And what about a Thunderbolt->DisplayPort? Or a HDMI->DisplayPort?
My monitor supports up to 100Hz, but if I can get it to 60Hz I'll be super happy already.
