Vec550 4k Verified ~repack~
Note: This review is based on the 2022 V-Series (V555x-K6), which is the most widely available 55-inch VIZIO 4K model in the current market.
The verification includes a physical layer test using a 5-meter passive copper HDMI cable (a worst-case scenario). The device must maintain a bit error rate (BER) of less than (10^-9) (one error per billion bits). Active cables, extenders, and fiber optics may still earn certification, but they must pass the same BER test. vec550 4k verified
