It's not so much about using a wrong port, and more so about freeing up the more capable ones for needier devices.

The port matters more than you think with your Blu-ray player.

Use the wrong cable or port, and you'll miss out on Dolby Atmos.

If you're someone who needs to (or likes to) take their work on the go, a portable monitor will make a huge difference. These are my favorite that I tested.
