All of which gives you a lot of options.

On the left side of the PT5 III is one HDMI video input port that supports resolutions up to 4K DCI at 30p, along with a 3.5mm headphone jack and a 3.5mm microphone input. A HDMI output port that supports resolutions up to 1080p60 is situated on the right side of the monitor.
