I just installed the 4D-Tech Sync3 upgrade into my 2014 F150 King Ranch. The only thing that bothers me about it is that the backup camera image is washed out (brightness to high?) compared to the image I got from my old sync2 equipment (much more contrasty). I checked my wife's 2016 Expedition, and it's the same - washed out.

Is there a fix for it, or some way to add contrast or reduce brightness?

 

I came from a '19 Ram and my '19 sync 3 looks like hammered hell compared to it. So yeah mines washed out too.
