Was walking down the dock and noticed that the screen on my buddies' E120W seemed brighter than mine...
So we cranked up both units to max brightness and his is definitely brighter.
My question is whether there is a way to adjust the max brightness in the unit's hardware somewhere... and why his would be brighter. Both units are relatively new.
Does anyone know if there's a resistor or potentiometer I can change out/ adjust?
(i understand the warranty risk)
Thanks in advance...

Don't have any idea how to increase max brightness, or if one would want to, considering your acknowledgement of the probable warranty issues.
A couple of questions and things to consider. First, are the batteries on both boats of similar capacity and charge state? Could the brighter display be connected by higher gauge wires and be connected to batteries that are more fully charged?
Are you looking at both displays from the same angle? I know that if I look at my display off-axis, or if I'm wearing polarized sunglasses, that SIGNIFICANTLY changes the apparent brightness.
I know there's a place somewhere in one of the menus that shows system voltage. I'm not at the boat now, but if you navigate down through the maze of choices, you should be able to find that item. A comparison of what the two boats show might tell volumes.
Just my buck - fitty (no, I'm not the Loch Ness monster from South Park). Good luck,

I don't have the e-series but the c, but I noticed the same issue on mine. I really thought something was wrong with it because I could hardly see it in the daylight. Turned out to be what marinerjoe said - low voltage. Seems Raymarine products are especially sensitive to voltage and mine was low and was being drawn down by other loads from my bus work. Ran a dedicated line straight from the battery through a switch and a fuse and it got real bright again. Might want to look at voltage as stated. Hope this helps...
