Which HDMI cable do you actually need?

When a cheap HDMI cable is fine, when to pay for certified Ultra High Speed, and how fiber HDMI works for long and in-wall runs.

HDMI cables range from a few dollars to well over a hundred, and the expensive ones mostly aren't better. Here's when the type matters.

For most things, any working cable is fine

A streaming stick, cable box or Blu-ray player at 4K and 60 frames per second runs fine on almost any modern "High Speed" HDMI cable. Gold plating and braided jackets are mostly looks.

When it matters: certified Ultra High Speed

Pay a little more for a cable marked Certified Ultra High Speed (48 Gbps, "HDMI 2.1") when:

• you're connecting a PS5, Xbox Series X or gaming PC and want 4K at 120 Hz;
• the cable feeds a soundbar through eARC with Dolby Atmos;
• the cable goes inside a wall, because replacing it later means opening the wall again.

The certified ones carry a label with a QR code you can scan to confirm they're genuine. They aren't expensive.

Long runs: fiber HDMI

Ordinary copper HDMI gets unreliable past roughly 15 to 25 feet at high resolutions. For longer runs, like a console across the room or a cable through a wall to a closet, use a fiber optic HDMI cable.

One catch: fiber HDMI only works one way. One end is marked "source" (the console or player) and the other "display" (the TV). Plug it in backwards and you get no picture.

Inside walls: check the rating

A cable run inside a wall should carry an in-wall rating: CL2 or CL3. It's printed on the jacket.

Tight spaces behind the TV

On a flush or tilting mount, a straight HDMI plug can press against the wall and strain the TV's port. A right-angle adapter turns the connection sideways.
