screen brightness on side scans

Looking at some of the images they appear a bit washed out and I was wondering if its the blue or you guys are setting the screen brightness instead of using auto-brightness?

Please expand on this I know that you can change the display lighting by use of the on off key but did not know of a auto setting on the screen brightness, I dont run my unit on auto Sensitity I like 15, 16, 17, setting because when you are trying to look at the screen and are going into a different depth it screws up the image of where you have been,

By setting it to zero it’s set to auto. This way as the bottom depth or hardness changes it sets itself to the highest value displayed as it goes up and down.
I always use the brown screen, I feel it gives the best contrast but some of the guys will always prefer the blue or grey.
