You don't need a switch to connect HDMI to a 4k display through HDMI. You only use 1 connector for HDMI and using 2 would not do anything. You can just plug it in like any display. As for a USB hub, you can just go buy one for relatively cheap prices. However, don't expect to be doing very much of anything at 4K unless you have a VERY powerfull computer to drive it. Backround knowlage: HDMI carries Video and Sound. It supports 4k at up to 30hz (so technically you max FPS would be 30)
