So today for the first time the left side 10" Dynon Screen has started to flicker a bit. It's no a flicker where I loose the information on the screen but more so the screen seems to get darker, then lighter. I thought at first it may had been an auto adjustment for the dimming based on ambient lighting but I was told the plane does not have such feature nor have I ever seen it do this before. Any ideas? Battery voltage looks fine!
