Setting the Video Gain and Lift (UTP Video Output)
You can adjust the video gain and lift settings when running video signals over
unshielded twisted pair (UTP) wiring.
The lift setting boosts the high frequency in the video to compensate for high
frequency losses over long cable distances. The greater the UTP wiring
distance, the higher the setting.
To enable/disable video gain:
• Select 7 Enhanced Features
1 Video Gain (UTP) ON or OFF
(default).
To adjust the video lift and gain pulse width modulation (PWM) levels:
1. Enable video gain.
2. Select 7 Enhanced Features
2 Lift PWM Level 0–100 or 3 Gain PWM
Level 0–100
3. Select a value between 0 and 100. Use Table 6-2 as a reference.
Table 6-2 Recommended Lift and Gain Settings by Cable Length
To lighten or darken the characters on the monitor screen:

4 Char White Level 0–100.
2. Select a value between 0 and 100 where:
•0 = darkest

•50 = default
CAUTION
Selecting values greater than 50 can cause the
phosphor in some monitors to burn the character images into the
monitor.
