I'm not sure if mine was ever super bright outside in the direct sunlight. I actually was outside today on our local airport runway doing video of my grandson running an RC monster truck. The sun was shining directly on my screen and I had trouble seeing what I was videoing. My Z Force is 1 and a half years old now. Maybe the screen is failing some. I don't know. Good question though.
Is it still under warranty?Yeah, it is definitely getting dimmer. I have on 100% brightness, which I've never had to do while outside, and the days are overcast, so it isn't full bright sun even. It is harder to see.
