Hi all.

I find my 16:9 screen is not bright enough in sunny days, even when I have the brightness control to maximum level.

Also, I understand the little hole beneath the screen is an ambient light sensor. Should it not serve to automatically modify brightness dependant on ambient light? It does not seem to work in my unit, i.e.: if I cover the hole with my finger there is no reaction whatsoever. Is this normal behavior?

Is there a way to tweak the unit to increase brightness? Maybe some internal variable resistor to be modified?

Thanks
