The ASUS PQ321Q True 4K UHD monitor provides stunning visuals with an ultra-high definition 3840 x 2160 resolution. The anti-glare 31.5-inch LED-backlit UHD display has a 16:9 aspect ratio & 140 pixels per inch (PPI) for highly-detailed visuals. By doubling the number of horizontal & vertical pixels, the PQ321Q True 4K UHD monitor gives you every bit of detail, far surpassing that of a Full HD monitor. With four times the resolution of Full HD (FHD) & over 8 million pixels, experience larger screen real estate & clarity you have to see to believe. The ASUS PQ321Q True 4K UHD monitor is built with an anti-glare Indium Gallium Zinc Oxide (IGZO) panel rather than traditional amorphous silicon. The IGZO panel supports much smaller transistors than amorphous silicon, which allows for much smaller pixels & much better detail. Couple with an ultra-wide 176-degree viewing angles on both vertical & horizontal planes, get a pristine image from virtually any angle. Whats more, the IGZO panel supports increased pixel transparency & reduced current leakage for increased energy savings.
