Good morning I recently purchased the HP Envy 27' Black 4k LED. I set it up and cannot figure how to enable 4k on the display. It is stuck in 1080P. I tried flipping through the menu and cannot find a way to turn it to 4k. Can anyone help? I bought this to use with my xbox One X. Do I need a special HDMI cord? The xbox settings say that the monitor is able to play 4k but I need to change the settings on the Monitor itself.
