elite 7 HDi

I saw where you have used the Elite 7 DF. Is there a base setting for the DI mode. All I see is a dark screen with faint images when I use it. I can't get anything like the clarity and definition I see some post on the forum.
Looks like a faded black and white photo negative.

The screen will be blurry in shallow water. I prefer the brown palette and I adjust the contrast depending on the depth of the water. Higher for deep water.
