What to look for in HDMI cable?

Any properly tested and certified cable will work as well as any other. There will be no difference in quality between a $5 cable and a $100 cable. Claims of "improved quality" or "higher definition" by manufacturers and sellers are misleading at best and might be considered dishonest.

By buying an HDMI cable from a reputable dealer, you should guarantee that the cable will be a certified design that is guaranteed to operate correctly.
