Philips and its sister brand AOC are claiming a world's first in gaming monitor tech. The Philips Evnia 27M2N5500XD and AOC AGON Pro AGP277QK are both 500 Hz 1440p gaming panels with 1,000 Hz alternative 1080p modes.
Size-wise, we're talking 27 inches. The actual panel technology has yet to be revealed. However, a number of the specifications that are available (via Display Specifications) point to a specific subset of IPS tech.
