Will 4K HDMI Cable Work With 1080P TV?

If you are purchasing a new 4K TV, you will probably need to purchase an HDMI cable in addition. With all the different types of cables out there, it cannot be easy to know which one is right for your requirements. The good news is that if you have a 1080P TV, and are thinking about buying a 4K HDMI cable, then chances are very high that it will work with your television without any issue.  In this article, we’ll discuss the question: Will 4K HDMI Cable Work With 1080P TV? Let’s get started, shall we?

Will 4K HDMI Cable Work With 1080P TV?

The answer to this question is yes. The latest HDMI 2.1 cables can support resolutions up to 4Kp60 at 10bit signaling, including HDR formats (defined by an open standard called HDR10), BT.2020 color gamut, and HLG (Hybrid Log-Gamma) used in broadcasting.

A few TV manufacturers may not provide these features properly for older models. Still, they should work anyway – with that said, you might run into some quality problems just like with any other signal chain failure point or insufficient bandwidth on the display side of things.

HDMI cables can provide a maximum throughput of 10.2 Gbit/s, so 4K content would take the system’s HDMI bandwidth over-limit without compressing the display screen size. It is theoretically possible for a high-end modern TV to display 4K images at 60 frames per second with its native screensaver and no other connected sources (such as games, consoles, etc.).

However, such bandwidth is not available through analog output methods like VGA or component video. The bandwidth requirements will c the use of an HDMI 2.0a compatible television capable of transmitting UHD signals at 3840 x 2160 pixels up to 120 Hz refresh rate.

It is also possible that a 4K HDMI cable will work with a 1080p TV.

HDMI cables are backward compatible, and a 4K HDMI cable can work on a 1080p television. The video signal quality will not improve drastically, but the clarity might see an improvement for some people. Although, if you have already upgraded or plan on upgrading your TV to 4K, then you’ll need an HDMI 2.0a high-speed standard to get the best experience from your new television set up.

The newest version of the A version includes support for higher resolution HDR formats such as BT2020 and HLG, which can offer improved display performance over older versions of the standard while maintaining compatibility with older ones.

Final Words

The way to find out is to test. One good thing about HDMI cables is that they are backward compatible, so it would not be an issue to have the wrong cable for your TV set. You can either buy an expensive 4K-compatible one or use the old 1080P cable and see what happens. If there’s no change in your picture quality, then you know that this isn’t something worth investing in. But, if it does work better than before, then it looks like now might be the time to upgrade after all.
