To toggle the video signal from 720p to 1080p on the Multi-Vu Pro Gen 2 system you do the following. With the unit powered on, hold the (+) button down for a couple seconds and the indicator light switches between red and green to indicate 1080/720.
Note: Due to some sonar units only accepting a video signal of 720p, the Multi-Vu Pro Gen 2 ships from the factory with a default setting of 720p.
