The HDMI cable standard can impact color and resolution, but newer versions are not required for 4K TV.
So, what you need to do is learn about the different types of HDMI cable, as well as wireless HDMI, and their potential benefits.
They all support 4K TV, but they do support it differently.
Do I need a 4k cable box for my 4k TV?
High-speed HDMI cables can carry 4K signals. The connection in your TV or receiver is what needs a specific HDMI version, and for 4K to work you need HDMI 2.0 or 2.0a. If you’ve bought your TV and other gear within the last 2 years, you’re probably all set (and your cables will almost certainly work).
Does the type of HDMI cable matter for 4k?
It’s important to remember that all High-Speed HDMI cables will carry a 4K video signal. If you bought your cables after 2009, your 4K content should reach your screen. HDMI cables tested under version 1.4 should carry 4K but they may not do it as well as you’d like.
Do expensive HDMI cables make a difference?
OK, so not all HDMI cables are literally the same. Better made cables may even last longer. “Better made” doesn’t have to mean more expensive. No matter what, though, there is absolutely no picture or sound quality difference between a $3.50 cable and a $1,000 cable.
How long can a 4k HDMI cable be?
Like many video, audio and data cables, HDMI cords can suffer from signal degradation at longer lengths—50 feet is generally considered the maximum reliable length. And it’s rare to see an HDMI cable longer than 25 feet in a store. Even online, cables more than 50 feet long can be hard to find.
