The best HDMI 2.1 cables of 2026
Which HDMI cable you need for 4K at 120Hz, how to spot a real certified one, and when the cable in the box is fine.
For a PS5, Xbox Series X or gaming PC at 4K 120Hz, buy any certified Ultra High Speed HDMI cable, such as the Zeskit Maya or Monoprice 8K Certified. Look for the certification label with a QR code. For runs longer than about 15 feet, use an active fiber cable. A streamer like the Apple TV 4K does not need HDMI 2.1. For TVs and streamers, see our best HDMI cables.

Quick picks
The picks
Zeskit Maya 8K
A certified Ultra High Speed cable with a braided jacket, sold in lengths from 3 to 10 feet. It carries 4K at 120Hz, VRR and eARC.
The braid makes it stiffer than a plain cable.
Monoprice 8K Certified Ultra High Speed
Certified, cheap and available in many lengths, which matters more than any other feature.
Plain styling with a thick jacket.
Belkin Ultra High Speed HDMI 2.1
Certified and sold in Apple, Best Buy and most big-box stores when you need one today.
Costs more than Monoprice or Zeskit for the same signal.
Active fiber HDMI cable
Fiber cables carry a full HDMI 2.1 signal over long distances, such as through a wall to a projector, where copper cables fail.
They only work in one direction. Plug the marked Source end into the console or receiver.
Do you need HDMI 2.1?
You only need an Ultra High Speed cable for 4K at 120Hz or 8K. Streaming devices, cable boxes and most Blu-ray players output 4K at 60Hz, which a Premium High Speed cable handles.
Plug the console into an HDMI 2.1 port on the TV. Many TVs have only two, often labeled 4K@120Hz. The wrong port caps you at 60Hz no matter which cable you use.
- Need it: PS5, Xbox Series X, gaming PC on a 120Hz TV
- Don't need it: Apple TV, Fire TV, Roku, cable boxes
- eARC: any High Speed cable with Ethernet works; Ultra High Speed is safest
HDMI 2.1 vs 4K: what's the difference?
They describe different things. 4K is a resolution: a picture 3,840 pixels wide by 2,160 tall. HDMI 2.1 is a version of the HDMI standard, and it sets how much data the connection can carry.
4K at 60 frames per second fits in HDMI 2.0, which is what streaming devices, cable boxes and most TVs from the last several years use. HDMI 2.1 roughly triples the bandwidth, which makes room for 4K at 120 frames per second, 8K, and gaming features such as variable refresh rate (VRR).
A box that says "4K HDMI cable" tells you little, because cables are rated by speed, not version. Look for "Premium High Speed" for 4K at 60Hz or "Ultra High Speed" for HDMI 2.1, each with its certification label.

Questions
What's the difference between HDMI 2.1 and 4K?
4K is a screen resolution. HDMI 2.1 is a version of the HDMI standard with more bandwidth. You can get 4K over HDMI 2.0 at 60Hz; you need HDMI 2.1 for 4K at 120Hz or 8K.
Is an 8K cable the same as HDMI 2.1?
Usually. Look for 'Ultra High Speed' certification rather than '8K' on the box.
Do expensive HDMI cables look better?
No. HDMI is digital: a certified cable either carries the signal or it does not.
What length can I use?
Copper Ultra High Speed cables are reliable up to about 10 to 15 feet. Use fiber beyond that.
