How to connect MacBook Pro (2020) to ultra widescreen monitor? I have an ultrawide monitor that's 3840 X 1200. It works perfectly fine with my windows laptop.
I now need to connect my work MacBook Pro provided to me, but under the list of resolutions (and extended hidden resolutions) none of them come close.
Is it a matter of the cable I'm using? I'm using a HDMI cable with a usb-c adaptor on the end to connect it to the MacBook.
Besides the other answer, you might have better results with a DisplayPort cable if your monitor supports it. My 3440x1440 monitor for instance works at 100hz with DisplayPort and only 60hz with HDMI.
