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
(default).
To adjust the video lift and gain pulse width modulation (PWM) levels:
1. Enable video gain.
2. Select 7 Enhanced Features
Level 0–100
3. Select a value between 0 and 100. Use
