HDMI passthrough is the most important feature that you aren’t using

HDMI has been around for decades now, but it feels like people are still finding out many things about the format. You might know by now that not all of the cables are the same, even if they have the same connection. In 2026, you should be using HDMI 2.1 cables, or at the very least, HDMI 2.0. In fact, you need either of these two cables to utilize a very underrated feature in HDMI passthrough.
