Hello all, I am new to this forum and I am wondering if anyone may have the Calibration settings for a VIZIO - E420VL LCD HDTV. i am a little thin on cash to pay an expensive Calibrator right now. My HDTV is hook-up to a set-top-box from Time Warner Cable; Model # Samsung SMT-H3050 and Also a Samsung Home Entertainment System.
I would appreciate any help anyone could give, thanks in advance and Happy Holidays.
