Display Enlightment by NCX

I reviewed the Dell S2719DGF (144hz 2560x1440 8 bit AUO TN from 2018) which has better image quality than the S2716DG (144hz 2560x1440 8 bit AUO TN from 2015) , but has worse image quality than the BenQ Zowie RL2460 since it can properly cover SDR (HTDV/REC 709 & sRGB) color spaces while both Dell monitors over and under-saturate colors, as well as can come with low preset gamma (the S2719DGF I tested came with sub 2.0 preset gamma):





The BenQ Zowie (6 bit +FRC AUO TN panel) can fully cover both SDR color spaces (HDTV/REC709 & sRGB) without any under-saturation and only a bit of under-saturation while the Dell S2719DGF significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space, and does so significantly more when un-calibrated.  When un-calibrated it significantly over and under-saturates some colors compared to both the HDTV/REC 709 and sRGB color space.  The top left side of the triangle (HDTV/REC 709 color gamut) falls short resulting in the under-saturation of blue and medium to dark greens. Medium to light greens, yellows, oranges and some reds are all over-saturated, a phenomenon typical of AUO panels, including both their 27" 2560x1440 and 32" 3840x2160 AHVA (more balanced or pure) panels which also over-saturate the same colors resulting in green and yellow tints to browns, greys and whites, even after calibration.

Keep in mind that the S2719DGF is calibrated and has its gamma fixed in the below comparison versus being too low out-of-the-box and significantly more washed out.  Click here to see comparisons of the Dell pre-calibration or un-calibrated versus calibrated to see what a unit with low-preset gamma looks like.
