Best 240-280hz with Nvidia G-Sync

Blur Busters G-Sync Input Lag Testing & Optimal Lag Reducing Game Settings

#1 Asus VG279QM (48-280hz Nvidia G-Sync) IPS equivalent (AUO AHVA)
#2 AOC AG251FG (30-240hz Nvidia G-Sync) TN panel
#2 Acer XN253QX (30-240hz Nvidia G-Sync) TN panel
#2 MSI NXG251R (30-240hz Nvidia G-Sync) TN panel
#3 Acer XB2522Q bmiprz (30-240hz Nvidia G-Sync) TN panel
#4 Alienware AW2518H (48-240hz Nvidia G-Sync) TN
#4 Asus PG258Q (30-240hz Nvidia G-Sync) TN panel


The VG279QM is a fully adjust-able, matte, 1920x1080, 280hz AUO AHVA panel with back-light strobing (ELMB), Nvidia G-Sync (48-280hz), Displayport, 2x HDMI 2.0 and 3.5mm Audio Out.  The VG279QM is preset to the Racing Game Visual Mode which is very accurate and almost properly covers the sRGB color space, but the unit PC Lab PL came with slightly too low gamma (2.1-2.2) versus the nearly linear 2.2 gamma Playwares and TFT Central measuredThe VG279QM slightly over-saturates greens, oranges, reds and yellows by over 10% but is otherwise very accurate.  The VG279Q supports HDR, but it is best lest off since it lacks almost all of the features required for true HDR, especially in regards to the DCI-P3 color space coverage since it peaks around 80%.  The overdrive is preset to the Trace Free 60 setting which provides the best performance at 240hz whileTrace Free 80 speeds up the pixel response times without obvious overshoot at 280hz.  Trace Free 60 causes some obvious overshoot at 60hz; Trace Free 20 slows down the pixel response times and gets rid of most of the overshoot at 60hz, but is a bit slower than Trace Free 40 which TFT Central recommends.  The VG279QM has negligible input lag according to 2/3 of the reviewers to measured the delay, and balanced and fast overdrive which provides pixel response times which are only slightly slower than the fastest TN panels like the Acer XF252Q.
Les Numeriques measured (middle screen) a 9.7ms delay with the Leo Bodnar device at 60hz which is nearly as low as possible.

PC Lab PL measured a 27.5ms delay with a high speed camera.  27.5ms is very high for a gaming monitor.  This could be a mistake, a 60hz measurement or a different version of the monitor.

Playwares measured 2-3ms at 280hz and 17ms at 60hz with the SMT Tool.

The Acer XN253QX, AOC AG251FG and MSI NXG251R have vastly superior preset color accuracy compared to the rest, but there's only one review for each so I don't know how consistent they are.  All three also offer nearly identical gaming performance (low input lag and fast overshoot free pixel response times), so I can not pick a winner until more reviews come out.

 The Acer XB2522Q and Asus PG258Q are inconsistent and can come with mediocre or low preset gamma which results in washed out colors. The Asus comes with intentionally over-saturated colors which results in detail loss while the Acer does not. This also applies to the 144hz Asus MG248Q and PG248Q.  The Alienware is also inconsistent preset color accuracy (gamma) and contrast wise, is inaccurate at best (preset gamma neither follows the sRGB or HDTV/REC 709 standard and causes black crush), but is not intentionally over-saturated and is cheaper than the Asus.
