Questions & Answers for Belkin UltraHD High Speed 4K HDMI Cable (2m)

4K is just the resolution (3840×2160px). There is a bit more to it. HDMI cables are differentiated by their bandwidth: 5 Gbps (original standard), 10 Gbps (High Speed), 18 Gbps (Premium High Speed), 48 Gbps (Ultra High Speed). The required bandwidth is determined by resolution, frame rate, bit depth, chroma subsampling. If you intend to watch at some point HDR content and/or high frame rate content, in combination with 4K, then you will want at least a 18 Gbps (Premium High Speed) cable. Any such HDMI cable will suffice for equipment with HDMI 2.0/HDCP 2.2 ports. Note that all commercially available 4K content requires HDCP 2.2, which requires HDMI 2.0 ports. So while lower bandwidth HDMI 1.4 could be sufficient for *some* 4K content, in practice you would need higher bandwidth capable HDMI 2.0 equipment to view 4K movies anyway. To avoid that the cable can become the bottleneck for high resolution viewing, it is advised to use at least 18 Gbps (Premium High Speed) HDMI cables, all the way from source to output.

HDMI cables all have the same port on the end. The difference is that the newer version of the cable 2.1 (the most commonly used is 2.0) in this case has a higher bandwidth enabling 4k video at 140hz (the hertz rating is the FPS) where as the older cable will only do 4k at 60hz. the answer is yes this cable is compatible with any TV, monitor, dvd player or many other products as long as they have a HDMI port on them, but if you buy this cable or any other HDMI 2.1 cable it will allow for better quality and future proofing if you decide to get a better tv or other HDMI compatible product.
