Use the test equipment or examine the displayed video image with a critical
eye to determine which video signal — red, green, or blue — is most shifted
to the left.
Adjust the leftmost video signal to the right until all three colors are
converged.

If either of the two the remaining colors is left shifted, repeat steps 11 and 12.
Repeat steps 9 through 13 for all other outputs.
example, outputs 1 through 4 for an MTPX Plus 168).
If using an oscilloscope, apply a white field test pattern to one the local
(VGA) inputs on the MTPX Plus (figure 5-21).
If using a monitor, apply a Color Bars test pattern to one the local (VGA)
inputs on the MTPX Plus.
The Extron VTG 300 or VTG 400 are recommended to provide the test pattern.
Tie the local input receiving the test pattern signal to the output connected to
the MTP receiver to be optimized.
