To put it simply, when your HDMI cable is certified you know you are purchasing the best product.  If you have an 8K TV it wouldn’t be wise to use a cheap non-certified $5 cable. You would not know if your television is receiving the best input possible; whereas, a certified HDMI would give you the best quality viewing that your TV is capable of. Most lengthy HDMI cables fail to deliver quality content, so make sure you purchase a certified HDMI cable especially for longer cords.
