DETAILED VISUALS AND CLEARLY-DEFINED TEXT

ROG Swift OLED gaming monitors feature the latest generation OLED panels designed for greater efficiency and brightness. The sub-pixel layout provides extremely detailed visuals and clearly-defined text to upgrade the viewing experience.

ULTRA-REALISTIC COLORS

The PG42UQ gaming monitor features true 10-bit color depth and a cinema-grade 98% DCI-P3 gamut to deliver unparalleled realism. Each monitor is pre-calibrated to Delta E < 2 to ensure the very best color reproduction on its brilliant OLED panel.

CUSTOM HEATSINK
INTELLIGENT COOLING DESIGN FOR 8% LOWER TEMPERATURES*
The custom heatsink found in the PG42UQ offers more surface area for heat exchange to provide more efficient cooling performance, even in long gaming stints. The lower temperature enables better OLED performance with lower likelihood of image sticking. This robust fanless system operates silently to minimize distractions.

ANTI-GLARE MICRO-TEXTURE COATING
LESS GLARE, FEWER DISTRACTIONS
A special matte Micro-texture coating on the surface of the display significantly reduces glare. This allows the PG42UQ to display more accurate colors free of distracting screen glare.

GAMING
CERTIFIED NVIDIA® G−SYNC® COMPATIBLE
The PG42UQ delivers a seamless, tear-free gaming experience by enabling variable refresh rate technology as a default on NVIDIA GeForce® graphics cards.

RICH CONNECTIVITY

The PG42UQ has an array of connectivity options that cater to any gaming or streaming setup. It includes HDMI 2.1 and 2.0, as well as DisplayPort 1.4 (DSC) at the rear to connect to various devices. One USB port and a tripod socket on top of the monitor makes it easy to mount a camera. Lastly, there’s even a headphone jack at the bottom of the display.

IN-GAME ENHANCEMENTS
Uniform brightness
When activated, the ROG-exclusive uniform brightness function setting within the OSD menu decreases peak brightness to keep levels consistent for better viewing, even when changing the size of bright white windows. It also makes marathon gaming sessions much more comfortable on the eyes.

ASPECT CONTROL

For gamers that prefer playing on smaller monitors, the PG42UQ supports a range of aspect ratios to cast a 24", 27", or 34" image that can be shifted vertically to aid the viewing experience. See it all, and set the pace with the 0.1ms response time of OLED.
