Can I use an 8k HDMI cable on a non-4k TV?

The length of the cable is not the only factor to consider when buying an HDMI cable. You want to make sure that you buy a 4k capable cable and support all of your devices. An 8k HDMI cable might work on a normal tv, but you will run into problems with compatibility if you use it on a non-4k TV.

What is an HDMI cable?

An HDMI cable is a digital audio/video signal. It transmits both uncompressed high-definition video and digital multichannel audio. HDMI cables are the cables of choice for professionals who wish to pull high-quality video sources free from interference or distortion and eliminate any tedious frequency conversion requirements bypassing the signal natively, without any additional modifications.

How Do I Know If My TV is 4K?

  1. You can easily determine if your TV has 4K resolution by looking at the manual or the box that contains the details.
  2. User manuals often refer to the resolution as Ultra High Definition (or simply UHD).
  3. It could also be indicated in pixels (3840 x 2160).

Can I use an 8k HDMI cable on a non 4k tv?

You may use an HDMI cable to connect a specific 8k TV to a non-4k capable TV. To determine the maximum possible resolutions that your device supports, refer to the manufacturer’s technical specifications or product detailing pages on their website.

If your device is not compatible or only partially compatible with 4K signals per second, it will receive and process any input signal as 1080p instead of 4K input signal levels. It means that HD TVs without the specification could be connected directly for 1080p-quality video connectivity should it suit your needs better.

It will work, but you won’t see any of the 4K features because there is no way for your tv to understand what’s coming through an 8k cable. It means that the only difference will be a delay in processing and a drop in data flow speed.

HDMI 2.0 was launched in 2018. It supports 8K resolutions and higher with a maximum bandwidth of up to 48Gbps. HDMI 2.1 can handle 4K and up to 8K video at 120 frames per second with plenty of room. All 2023 TV models, as well as many 2020 high-end models, should support HDMI 2.1.

Is the speed of the HDMI cable important 

High-Speed HDMI cables support HDR and wide ranges of colors. Premium High Speed increases bandwidth to 18Gbps it will allow you to cover all consumer-level video sources. These cables are very popular now. Premium High-Speed cables can support 4K60 or 4K video at 60 frames per second with the ability for BT.


It’s important to know what type of connection your TV supports before buying an HDMI cable. If you have a 4K television, then the answer is yes! But if you don’t, it’s best not to use an 8k HDMI cable on a non-4k tv as it will only be a waste of money and time.
