I finally purchased and received my x rite color checker display pro and calibrated my monitor.
Its a Benq pd2700 q.
Set the profile to D65 and 120 luminance with 2.2 gamma and the largest tablet sample which has the most color samples. Yea I know for print 120 is high but I figure most of what I will be doing will be for web so hence 120.
So.... I'm having an issue with photoshop.
A test I found to see if things are set correctly is to make a new white layer and make a black to white gradient across it. It should look smooth black to white.
Mine does not. It is banded and also shows green and red bands.
I have reset color settings, see attached. These seem to be the favored settings by all the photoshop geeks I have found.
However,,,if I go to " assign profile" and change that to the monitor profile I created with the x rite the gradient looks perfect.
This operation is not recommended by everything that I have read so I am assuming I have something else set wrong somewhere.
The profile is correct in windows.
Photos come into photoshop as prophoto RGB 16 bit.
The banding does not appear in lightroom.
Any ideas or somewhere or someone anyone can point me to?
I have spent the last day and a half looking online for an answer to no avail.
Guess I can call Adobe tomorrow....oh boy...
I have attached 4 screen shots including the two gradients and the color settings. the banding shows in the screen shot on my monitor it may not on here.
Any help by anyone here on UHH will be most greatly appreciated.

The first thing that I would try is to check and see how many pixels per inch were in your new layer. If there were too few pixels that will cause banding no matter what else you do. You need at least 300 pixels per inch and you may need more than that to stop all banding.
