Setting MTPX skew
1. Connect an oscilloscope (preferred) or a monitor
(acceptable) to local output (VGA output) 1.
2. Apply a crosshatch test pattern to the input to be
optimized via an MTP transmitter.
3. Tie the input to be optimized to output 1.
4. 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.
5. If necessary, click Tools > MTPX Picture settings.
6. Adjust the skew setting of the leftmost video signal to the
right until all three colors are properly converged.
N
When the skew adjustment is set to zero, the MTPX Plus
cannot shift the rightmost video image to the left.
N
A 2-nanosecond adjustment is very fine. Up to 10
nanoseconds of delay may be necessary before you detect a
change in the display.
6
. Adjust the skew setting of the leftmost video signal to the
right until all three colors are properly converged.
7. If either of the two remaining colors is left shifted, repeat
steps 4 and 6.
8. Repeat steps 2 through 7 for all other inputs.
9. Connect an oscilloscope (preferred) or a monitor
(acceptable) to the MTPX twisted pair output to be
adjusted, via an MTP receiver.
10. Apply a crosshatch test pattern to one of the local (VGA)
inputs on the MTPX Plus.
11. Tie the local input receiving the test pattern signal to the
output to be optimized.
12. 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.
13

15
. If either of the two the remaining colors is left shifted,
repeat steps 12 and 14.
16
. Repeat steps 10 through 15 for all other outputs.
Selecting MTPX Plus Pre-Peak
N
MTPX Pre-Peak is available on the first half of the MTPX
Plus outputs (for example outputs 1 through 4 for an
MTPX Plus 168.
N
If the cable between the MTPX Plus and the receiver is
> 300’, turn the MTPX Plus’s Pre-Peak feature on. For
shorter cables, turn the feature off.
If necessary, click Tools > MTPX Picture settings and then click
in the ouput Pre-Peaking box to toggle Pre-Peaking on and off.
