I have one of those LG monitors, although mine has a usb-c input which also handles display-port (so it's 2xDP + 2xHDMI). What really bugs me with HDMI is that monitors and computers never seem to agree on the image standard and for some reason always default to washed-out colours, even when connecting a PC to a PC monitor (as opposed to a TV). Under Linux/X11 I know how to set it in full range mode [0], but I was using such a monitor at home and connected it the HDMI output of my gaming PC (Radeon GPU) and couldn't figure out how to fix the washed-out colours. In the end I bit the bullet and bought a display-port switch. Now windows complains about the "limited display connectivity" (the monitor has a USB hub whose upstream is the usb-c/dp connector), but at least the colours look OK. --- [0] `xrandr --output HDMI1 --set "Broadcast RGB" "Full"` IIRC
