I have my NEC 3090WQXi calibrated and profiled with an i12 colorimeter and SpectraViewII with the following parameters: D65(Target 6506K, Calibrated 6573K, Delta E 0.53); Luminosity Target 140 cd/m2, Calibrated 140.1; Black Point native: 0.43, calibrated 0.63; Contrast Ratio 218:1; gamma 2.2; Color Tracking Delta E 0.41.
Other settings: Primary Color Chromaticity: Use Factory Measurement; Calibration Priority: Best Grayscale Color Tracking; Color Correction (Uniformity across the screen): Maximum.
I have tried various luminosity settings from the current 140 cd/m2 down to 90 cd/m2 and back up, in increments of 5. While 140 is still slightly too bright, my prints are accurate in color but very slightly darker in my normal viewing light. I am anticipating buying a dimmable print viewer (either the Just Normlicht Color Master 2 DI or what appears to be a very similar GTI PDV 3ED. The GTI is about $100 more than the Just, and I am tempted to go with the Just, which looks to be a company as involved in professional color-critical applications as GTI...any thoughts on this?)
I decided to try some black-white gradients, both vertical and horizontal. At 100% I could see what I consider to be mild banding, more evident in the darker values. The banding was on the vertical as well as the horizontal gradients. The banding became more pronounced viewing at 200% and 300%. The banding occurred whether or not the gradients were done with dithering.
Is this normal for an NEC 3090? Does it also occur on LaCie and Eizo monitors of similar specs? Or am I being an obsessive pixel peeper? I have not noticed banding in the images I process on this monitor.
