Extended description of upgrade features
(it does not mean that the upgrade(s) option(s) shown include all of these features simultaneously):
IPS (In-plane switching) - Better viewing angles because of a different way of constructing the pixels. Colors will no longer shift if you look at your display from the side or from above.
IPS Professional Color - A wider range of physical colors reproducible by the LCD. A must-have for professional photography, print and publishing, available to you at a fraction of the cost.
120Hz - A maximum refresh rate of the display (most commonly 60Hz) dictates how many pictures your display can show per second. With a 120 Hertz upgrade, your new display can deliver double the frames each second for smoother motion and a much more immersive visual experience.
120Hz IPS - All of the advantages of a 120Hertz upgrade combined with wide viewing angles and improved color range.
