Do you need a 4k HDMI cable to connect your TV? The answer is it depends. Most new TVs have the ports necessary to support a 4k signal, but if you have an older model or are connecting your TV to a device that doesn’t support 4k, you’ll need the appropriate cables. Here’s everything you need to know about 4k HDMI cables and how to choose the right one for your needs.
There are many things to think about when you buy your new TV, but if it’s not 4K and HDMI compatible, then don’t worry. The process for buying cables is just like any other purchase in that there needs to be some compatibility match between what the device outputs (line) vs how another piece will accept them as input (HDMI port).

If one or both parts aren’t working together correctly, then either an inexpensive fix may solve all issues at hand, such as replacing individual components within each unit until they function correctly again; more drastic measures involve setting up entirely different wiring schemes from scratch – luckily this isn’t necessary.
Types of HDMI Cables:
There are four basic types of HDMI Cables. Given Below:
- Standard HDMI
- High-Speed HDMI
- Premium High-Speed HDMI
- Ultra High-Speed HDMI
Their Resolutions and Refresh Rate:
When pared down to the most basic information, the video resolution guidelines—as set by the HDMI Forum Technical Working Group that defines the specification—are:
Standard HDMI:
Up to 720p or 1080i resolution at a 30Hz refresh rate.
High-Speed HDMI:
Provides up to 4K resolution with a refresh rate of 30Hz.
Premium High-Speed HDMI:
Up to 4K resolution with high dynamic range (HDR) at up to 60Hz.
Ultra High-Speed HDMI:
Up to 10K resolution with HDR at a 120Hz refresh rate (4K video can refresh at up to 240Hz).
When to buy a new HDMI cable for your 4K TV:
If you need a high-quality HDMI cable to ensure your system is capable of playing 4K content at 120Hz or with HDR, then it’s time for an upgrade.

If the cables that come bundled with your device(s) don’t meet these requirements–say, if they can deliver top video quality but only output in Standard Definition (SD), make sure before purchasing more expensive ones by testing them first. Active cables cost more than passive ones, but their classification and certification determine the performance.
How do I know if my HDMI cable is 4K?
Have you ever bought an HDMI cable that didn’t support 4K Ultra High-Speed speeds but instead only had “High-speed” printed on it? When purchasing this new generation of televisions and Blu-ray players to connect them with our HDTVs, make sure not to get fooled by a low-speed rating.
If you want to ensure that your HDMI cable supports Ultra HD 4K resolution, check for the High-Speed logo. This is what a typical hi-speed label looks like, and some wires may have it on them as well.
