The Asus PB278QR and PB278Qs manufactured in 2014 use a semi-glossy or nearly grain free matte coating and a Flicker or LED PWM Dimming Free 2560x1440 8 Bit AHVA panel made by AUO while the original PB278Q used an 8 bit 2560x1440p Samsung PLS panel with 240hz PWM (source). Read about PWM Side Effects here.
Asus PB278QR Review by =DEAD= (Russian) confirms that it uses an AHVA panel.

Set the Trace Free (controls the pixel response times) to 20 to get rid of the overshoot ghosting.
