The Pinnacle of Display Innovation
QD-OLED harnesses the power of quantum dots to achieve unparalleled colour accuracy and brightness. Unlike traditional displays, QD-OLED leverages quantum dots that emit their own light, enabling a wide range of precise colours at an exceptional contrast ratio. With blue light as its source and a QD light-emitting layer that breathes life into colours, QD-OLED achieves remarkable luminance while preserving high colour purity and a wide colour gamut.

Protect Your Eyes From Screen Flicker
Flicker-free technology reduces flicker to give you a more comfortable gaming experience. Normal LED-backlit monitors adjust brightness using PWM (Pulse Width Modulation) which causes flickering and results in eye discomfort over long periods oftime. AOC flicker-free technology uses a DC (Direct Current) backlight system to provide a more comfortable and healthier viewing experience, minimising the effects of eye fatigue during work hours.

HDMI represents the leading digital video, audio, and data interface for high speed connections between ultra high-definition displays and a wide range of consumer electronics, including providing support for modern gaming consoles and PCs. DisplayPort allows for a range of devices to quickly and easily connect to your screen, delivering higher resolution, faster refresh rate and video transmissions free from input lag.
