The actual balance of brightness, contrast, colour, gamma etc is usually a very personal thing. (often set to over come variances in equipment)
However AH features "night" and whilst many may use utilities or just switch to alternate settings to over come its visual restrictions some consider this gaming but still are unable to see anything to allow even half decent game play.
Is there a way that HTC can communicate the visual effect and depth of vision it considers renders "night" (eg at 05.00 am) such that folk could adjust to obtain the "non gamey" effect HTC strive for.
