ASUS has announced a 27″ IPS 120Hz monitor with 2560x1440p resolution!
The ASUS MG279Q is a IPS LCD panel, with better colors and viewing angles than most 120Hz+ TN monitors!
The announced 5ms GtG rating may, however, prevent the ability to use LightBoost-style motion blur reduction modes. That said, it is exciting to see 120Hz+ finally officially arrive to many IPS panels!
UPDATE: This monitor supports FreeSync!
