Hi Golden: 57 is a nickname for a gentleman who uses program(Spyder(sp)that attaches to your TV) to adjust the blacks/whites/color/tint to their best point).While not as in depth as an ISF calibration he will spend 3 hrs approx (cost $100 is what it cost me) setting-up your entire home theater system codes etc!! I hope this helps
