Video Quality Adjustment

Video quality adjustment is done automatically to assure the image is as clear as possible. However, due to the different twisting rates of each pair of wires in the CAT5 cable, variations in the signal delays between the red, green, and blue channels will occur when the cable is longer than 300 feet. The variations could result in poor image convergence (i.e. instead of a white vertical line the user will see three vertical lines: red, green, and blue). These variations may be adjusted by changing the settings in the first three horizontal scroll bars. Changing the settings will vary the timing of the signals and ultimately balance them out.

To display the Video Adjustment screen, press <V> from the Settings Menu. (From the Command Mode menu press <T>-<V>.) An image with 4 horizontal bars (video components) will appear.

FYI: Video Quality Adjustment may need to be repeated if the CAT5 cable is changed.
