Best HDMI Cables in 2026

As I mentioned above, just because you’re buying a new TV doesn’t necessarily mean you need new HDMI cables, even if you’re upgrading to something with 4K and HDR. Over short distances, say less than 6 feet, just about any recent “high speed HDMI cable” should work fine. “High Speed” and “Ultra High Speed” are the classifications used by HDMI companies to indicate cables with the bandwidth to handle at least 1080p and 4K resolutions, respectively.

You can think of bandwidth as a pipe. You need to be able to put a lot of “water” through the pipe with 4K and HDR content. A broadband cable needs to be “big” enough to handle everything.

The good thing is, if it works, it works. For example, if you send a 4K HDR signal from your 4K Blu-ray player to your 4K HDR TV and the TV displays a 4K HDR signal, you’re all set. It is not possible to obtain a better image using another 4K HDMI cable. That’s not how technology works.

There are only two “failures” with an HDMI cable. The most likely thing is that you will not receive any signal: a blank or flashing screen. First, check that everything is connected correctly and that all settings on your HDMI device are correct.

The only other “failure” mode for HDMI cables is sparking. It looks like snow on the screen. It may be heavy enough to look like static, like an old TV tuned to a dead channel, or it may be random but regular flashes of white pixels. This means you will need new cables.

If the TV receives the same resolution you’re sending it at (for example, the TV says it’s 4K HDR when you send 4K HDR), you’re all set. A different cable won’t make that image sharper, brighter, or anything else.

Also remember that if any part of your channel isn’t 4K HDR, nothing is. If you connect a 4K Blu-ray Disc player to an old soundbar and then to a 4K TV, you will not be able to transmit a 4K signal to the TV. Additionally, some TVs only have one or two HDMI inputs. HDMI 2.1 (or newer) compatible. Also check your owner’s manual for this.
