Question: do you need a hdmi 2.0 cable for xbox one x?
Answer: On some televisions, only one of the HDMI outlets are 4K at 60 Hz, which is best for your X. Check your TV's manual to make sure you're using the right outlet. Also, if you needed a longer cable and didn't use one that came with your Xbox One X, be sure you're using a HDMI 2.0 cable that is rated for 4K.
