I have been using a new Pavilion 22xi for a couple of weeks, and color settings remain problematic after much trial and error. My primary concern at this point is the significant banding in gradients. It's difficult for me to imagine that this would be considered expected performance, but thus far I have not been able to significantly reduce it.
My display is connected via HDMI cable to a Mac Mini running OS X 10.9.1. I have explored a variety of adjustments to both native display controls and the OS X color profile. So far, banding in gradients continues. I welcome any advice as to what I might do; if there are other details I can provide, just let me know.
Thanks.
