Thank you for reply
The best of the setting up hardware so far shows these settings:
Preset Modes: Custom (R,G,B) = 100, 100, 100
Combined with Nvidia Driver Software "Adjust Desktop Color Settings":
All Channels - Brightness +45
All Channels - Gamma +45
All other settings so far are at default.
Monitor shows a noticeable Blue tint / bias and it has been difficult to compensate for that.
I will continue to work with the settings in hoping I will find some that are the proper display solution.
I do not believe I will invest in calibration hardware (Spyder3). If I am unable to find solutions that are satisfactory, I will contact Dell about a return and refund. I do not think a second unit will help much based upon search content that I have found so far.
I will update if new changes warrant.
