iiyama XB2779QQS

5120x2880 or 5K semi-wide gamut IPS panel with Plasma Deposition Coating.  The iiyama XB2779QQS over-saturates color significantly unless used with programs which support color management.

Matte 4K IPS with very accurate color presets, negligible input lag, but slower than average pixel response times for a 60hz AHVA/IPS/PLS panel.  It has a fully adjustable stand, Displayport, Dual-Link DVI (1440p), HDMI 2.0, 2x UXB 3.0 (1x fast charging), and 3.5mm Audio In and Out.

Below are PRAD's oscilloscope measurements of three 27" 4K monitors pixel response times, including the VP2780-4K from 2015 which I own.  The iiyama's +2 overdrive setting speeds up the pixel response times significantly, but also causes overshoot ghosting.  The +1 setting provides a better balance between speed and overshoot.  The iiyama's overdrive is fine for casual gaming, but there are better options.
