Display Enlightment by NCX

All monitors had their brightness settings reduced to output 140cdm/2 before and after calibration.  I had to reduce the S2719DGF's Contrast setting to calibrate it which is why the contrast dropped to 680:1.  A 2200 lumen 5000k LED ceiling light is the only light source.

To properly compare the photos right click on the photos and closely inspect larger versions in a new tab, especially if experiencing trouble with the spoiler pop downs.  Since the S2719DGF has nearly perfect preset color accuracy the main difference seen in the photos is caused by the brightness and darkness of colors and shades which is determined by the preset gamma which is too low, and results in colors and shades being brighter, or more washed out than they're supposed to be.  The un-calibrated versus calibrated differences are very obvious when comparing a TN panel with low gamma and vertical gamma shift to an AHVA/IPS/PLS or VA (A-MVA, S-MVA, S-PVA, ect) panel.
