Asus 240hz

Asus PG258Q

The Asus PG258Q has a fully adjustable stand, a fake frame-less casing with a perceived black depth reducing inner black bezel, Displayport (240hz, G-Sync and ULMB), HDMI (60hz) and 2x USB 3.0 ports. The PG258Q is preset to the Racing mode which suffers from inteionally over-saturated colors (reduce Saturation setting to fix) preset color accuracy (gamma) variance (low preset gamma averaging around 1.8 or 2.1-2.2), though units with low gamma can be improved by switching the gamma setting from 2.2 to 2.4 on units with low preset gamma. The PG258Q's sRGB color space coverage is also below average in the 90-93% range.

Asus XG258Q

Added Asus XG258Q Review by Playwares to my

Matte 1920x1080 240hz AUO TN panel with AMD Free-Sync (48-240hz range) and back-light strpbing (ELMB @100/120hz) and good preset color accuracy, as well as gamma controls to combat potentially low preset gamma (washed out colors) 240hz panels can come with.

Asus  VG279QM

Review by Ashun (high 60hz input lag & back-light strobing analysis)
Review by =DEAD=
Review by Global HD Russia (2.06 gamma)
Review by Les Numeriques (skewed & slightly too high gamma; warmer 6180k color temperature)
Review by PC Lab PL (27.5ms delay; measured at 60hz, different firmware or a mistake?)
Review by Playwares (2-3ms delay at 280hz and 17ms at 60hz)
Review by TFT Central (2.3ms delay at 240hz)

Fully adjust-able, matte, 1920x1080, 280hz 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. 

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 is likely a 60hz measurement since Ashun measured a 34ms delay at 60hz and a negligible 2ms at 280hz.
