I got a new 24" HP LP2475w LCD a couple weeks ago. It's a wide-gamut monitor, and it's great for the price, as it is one of the few IPS monitors available.
I've always calibrated my older, smaller LCD to a luminance value of ~120, but it seems too bright on this display. Almost painfully bright. Maybe because it's just because it's much bigger than what I'm used to, and it's emitting light from a larger surface area than my old LCD.
So I turned down the brightness and recalibrated, and now have a luminance value of 102 which is far more comfortable to my eyes. Is such a low luminance value acceptable? Someone told me that LCD luminance values should never go below 120. True or false?
