+Displayport, 2x HDMI Inputs (1x HDMI 2.0), 4x USB 3.0
+48-155hz AMD Free-Sync
+Grain, haze and sparkle free matte coating
+Lack of obvious image quality loss when switched from 60 to 144hz
+Balanced 144-155hz overdrive with no obvious color streaking of overshoot ghosting
+Very accurate and linear preset RGB accuracy resulting in pure and color tint free greys and white

+No obvious back-light bleed, glow or color uniformity issues-
-Obvious image quality difference between HDMI and Displayport
-Very low Displayport gamma (1.9) resulting in obviously washed out image quality
-Gamma drops at 155hz resulting in more washed out image quality
-Displayport and HDMI image quality differences
-Perceived black depth decreasing black bezel
-Low 700:1 contrast after calibration
-Slow 60hz pixel response times for a TN panel? TN panel with vertical gamma shift
? TN panel with very restrictive viewing angles
? HDMI cable included instead of Displayport
TN panels are by far my least favorite type of LCD panel, and I cringe when I seriously consider testing them, but I must note my surprise at the improvements the S2719DGF offers. The improvements the S2719DGF offers are the completely grain and sparkle free matte coating, reduced banding in dark scenes, very accurate color presets (RGB balance) which provided pure, or tint free greys and whites which only high end professional oriented monitors like my Viewsonic VP2780-4K IPS panel usually offer. The improvements the S2719DGF offers are sadly mostly negated by the low preset gamma (obviously washed out color and shades), and 60hz overdrive performance, though, the low gamma is clearly far more important since it can not be improved without a colorimeter and ICC profile which requires third party enforcement (Color Sustainer) to ensure PC games use the ICC profile.
The S2719DGF comes close to being an above average TN panel, but the washed out colors and shades caused by the low preset gamma can't be forgiven since it lacks gamma settings to raise the gamma unlike Acer, AOC, LG and Viewsonic 144hz+ TN panels which have at least two settings to lower and raise the gamma. I vastly prefer the calibrated image quality of the S2719DGF to the
144hz 1080p Acer XF240H and Viewsonic XG2402 I recently tested, however I think both are a better value since there are no 144hz AHVA/IPS/PLS panels available in the same price range.
I highly recommend saving up an addition 100-150$ for an Acer XF270HUA, Asus MG279Q, Nixeus Edge 27 or Pixio PX277H which all use 144hz AHVA (marketed as IPS) panels with AMD Free-Sync. If spending more is not an option and the superior viewing angles the Dell offers are not a priority (especially when subject to the gamma lottery), I recommend saving money and opting for a 144hz 1080p AHVA/IPS, TN or VA panel.
