Lights Off Comparisons

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.

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 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.

The Acer suffers from obvious back-light bleed in the bottom right corner.

Back-light bleed or uniformity issues are more obvious if a monitor has low contrast.  The S2719DGF does not suffer from obvious back-light bleed, even once the contrast is reduced from 960 to 680:1 after calibration.  My panel has a few impure spots, but no obvious bleed during normal use.

The XG2703-GS also suffers from a bit of back-light bleed in the bottom right corner.
