The RGB Skew Calibrator provides perfect skew delay correction. This delay or skew is a result of transmitting RGB signals over CAT5 cables and causes color distortion and improper alignment. Skew become significant when using CAT5 over longer distances. The calibrator features 62ns total delay with 2ns delay step increments, memorize & button lock function, and RGB up/down buttons. Includes 3ft HD15 M/M cable and power adaptor. (Connectors: HD15 Male to Male)
