When I had an anti-glare film on mine I had to adjust the brightness about three quarters of the way up. Now I am using a crystal film and I only need it set about half way up.
I loved no fingerprints of the anti-glare but I really missed the clarity of the crystal films so I switched back to them.
i think it really depends on what type of shields you use.
I'm on my 2nd shield (1st one pealed off..) and am liking this one.
doesnt leave too many fingerprints and its CRYSTAL clear
