Spoke with Eizo tech support and of course the monitor should be using the
10 bit LUT to produce banding-free gradients at any calibration gamma and/or
PS work space gamma. Here's the wierd thing. If I recalibrate to a 2.0
gamma, images assigned with my PS custom grayscale work space of gamma 2.0
show no banding, but images assigned a 1.8 or 2.2 work space do exhibit some
banding. Similarly, images with a custom RGB 2.0 gamma work space show no
banding while ProPhoto and Adobe RGB tagged gradients show some
banding.Having to match a monitor calibration gamma to a work space gamma is
CRAZY and seems to me to indicate I have a faulty unit. Especially since it
seems Roger and Michael are not seeing this issue with their EIZOs.
A 10bit LUT used for calibration would
