When it comes down to 4K TV, you do not need to pick up special HDMI cables.
In other words, don’t immediately toss out your old HDMI cables for the newest HDMI 2.0a or 2.1.
The HDMI cable standard can impact color and resolution, but newer versions are not required for 4K TV.
Does 4k HDMI make a difference?
Different types of HDMI cables do exist, but their designations indicate how much data they can carry. (Spoiler: There’s really no such thing as a 4K HDMI cable.) High Speed HDMI: Up to 4K resolution (including 1080p) at 30Hz. Premium High Speed HDMI: Up to 4K resolution with high dynamic range (HDR) at up to 60Hz.
Do HDMI cables make a difference in picture quality?
Here’s the deal: expensive HDMI cables offer no difference in picture quality over cheap HDMI cables. CNET has mentioned this before, but here’s the science of why. The first thing to understand is what’s transmitted over the cable in the first place. HDMI uses Transition Minimized Differential Signaling, or TMDS.
Will 4k HDMI cable work with 1080p TV?
Which is to say, your TV can have HDMI 2.0 inputs, but your HDMI cable is just an HDMI cable. Any High-speed will do. So even if you bought a High-speed cable when all your gear was 1080p and HDMI 1.4, it will probably work now with 4K HDR and HDMI 2.0a gear.
Which HDMI port is best for 4k?
Thus, for any modern 4K TV that’s going to connect to any modern 4K UHD media streaming or playing device, the spec you’re really after is HDMI 2.0. This newer version of HDMI offers 4K video resolution at a smooth, decently fast 60 frames per second (60Hz refresh).
