Most HDMI cables on the market already support 4K resolution.
Sorry, there was a problem. Please try again later.Not usually, but you want to watch length vs. quality of the HDMI cable, and also what you connect to it. If it is very long, or runs through a noisy environment, you may need to invest in a higher quality cable. Just make sure it is HDMI 1.4 compliant, and you will likely be OK.
