Connectivity
What is HDMI and what is it for?
HDMI is the connection that carries digital picture and sound over a single cable. It is used to connect a laptop, a console or a media player to a TV, a monitor or a projector. The version of the port defines the maximum resolution and smoothness it can transmit.
What changes between versions
All versions use the same connector and are compatible with each other: the link works with the capabilities of the older of the two. HDMI 2.0 carries 4K at 60 frames per second; HDMI 2.1 reaches 4K at 120 and 8K.
To watch a movie, almost any version will do. Where it matters is with consoles and high refresh rate monitors, and there the cable also has to support that speed.
ARC and protected content
HDMI ARC (audio return channel) lets the TV send sound to a soundbar over the same HDMI cable, with no separate audio cable.
Streaming services protect their video with a system called HDCP. If any device in the chain does not support it, the picture may not show even though the cable is properly connected.
What to check before you buy
- Count how many HDMI ports you need and how many the device has.
- For a console at 120 Hz, both the port and the cable must be HDMI 2.1.
- If your laptop only has USB-C, confirm that port has video output or use an adapter.
