Ghosting/Overdrive Performance

The Response Time setting which controls the pixel response times in the Game Menu is preset to Fast, and is the best setting for 144-155hz use.  The Super Fast setting causes very obvious overshoot ghosting which is bright, colored and transparent dark glowing trails which appear during motion.

155hz Dell S2719DGF vs 144hz Viewsonic XG2402:

The extra 11hz offered by the S271DGF overclocking feature does not ad obviously perceptual improvements over 144hz, but the Fast Response Time setting offers very balanced and fast overdrive performance on par with fellow balanced and fast overdriven 144hz TN panels such as the Viewsonic XG2402 featured in the comparison above.  There's no obvious overshoot ghosting, very minor color streaking and no color smearing unlike 144hz VA panels.  The S2719DGF is slightly faster than the 144-165hz 1440p AHVA (marketed as IPS panels), and free from obvious overshoot ghosting unlike its predecessor with G-Sync, the Dell S2716DG which has less balanced overdrive. 

60hz Overdrive Comparison:

At 60hz the S2719DGF offers vastly superior overdrive performance compared to the S2716DG which suffered from very obvious overshoot ghosting at 60hz, but has slower pixel response times than the S2716DG, as well as the best 60hz AHVA/IPS/PLS panels like the Acer XB321HK (4K matte AUO AHVA panel).  The S2719DGF is also a bit slower than TN panel using monitors such as the BenQ Zowie RL2460, and the Acer XF240H and Viewsonic XG2402 at 60hz.  The S2719DGF suffers from some slight color streaking, and a bit more motion blur than the best 60hz competitors, however, its overdrive performance is still passable and good enough for console gaming, assuming one can put up with TN panels dull and vertically uneven colors, and very restrictive viewing angles.
