A:Answer In most cases, you can use your existing HDMI cables. Most reasonable cables (not from a $ store) will likely work. Sure, they'll try to sell you a $30 cable, but I'm using $10 ones that are > 5 yrs. old, between my UltraHD BluRay and the new 4K TV, and it works fine. With 'digital'...it either works, or doesn't. Easy to try it and see. No damage possible.
