A:AnswerUse a display port cable from your pc and a usb-c to hdmi cable from your Mac and it will work. You’ll need to either use PIP (picture in picture) or change inputs but won’t need to mess with the wires.
A:AnswerThe monitor is only 60hz. It'll still look great, your GPU can definitely handle it but you are missing out on how much better fps you could be getting with the GPU you have. I'd recommend at least 144hz monitor.
A:AnswerNo, that's an awful idea with this monitor, the VESA mount is at the very top of the panel. Get a monitor with a center or bottom VESA mounting location, you be better off.
A:AnswerIt does 60hz at 4k but only if you use the HDMI2 input or display port. HDMI1 is 30hz at 4k max (or higher hz at lower res). Google the specs online. I use it for pc gaming for 4k@60hz.
A:AnswerWhy not say HDMI? you are limited by the input to the monitor, use either HDMI of DisplayPort, however there are adapters you can use if you computer is older and uses older video outs. Visit your local computer store for help.
