HDMI cables are backward compatible, so an HDMI cable with 4K capabilities will transmit 1080p video, which is the resolution of your 1080p TV.
Can I use a 4K HDMI cable on my 1080p TV?
Will a 4K HDMI cable work with a regular TV?
The HDMI cable standard can impact color and resolution, but newer versions are not required for 4K TV.
What’s the difference between a regular HDMI cable and a 4K HDMI cable?
There really is no difference between a cable marketed as 4K and one that is not. But there is a label that does matter, and that is the speed rating. Speed will dictate the maximum bandwidth allowed by the cable.
Will a 4K HDMI cable improve picture quality?
A 4K HDMI does not improve audio and video quality better than other compatible non-4k ones. As long as the cable can accommodate the bandwidth required to show 4k content, you’re good to go. An HDMI cable only transmits signals.
