Product Description

Asus ROG Swift OLED PG42UQ 41.5" UHD Gaming Monitor - Black



The ROG Swift OLED PG42UQ is a 41.5-inch 4K OLED gaming monitor that features an anti-glare Micro-texture coating to reduce reflections to ensure you see more accurate onscreen colors. Its superfast 138 Hz (overclocked) refresh rate and blazing 0.1 ms response time delivers incredibly immersive gaming on a larger scale. Plus 98% DCI-P3 gamut, true 10-bit color and Delta E < 2 ensure true-to-life colors and the darkest-possible black hues.


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.


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.


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.

*Compared to ROG monitors with no heatsink.



A special matte Micro-texture coating on the surface of the display significantly reduces glare. This allows the PG48UQ to display more accurate colors free of distracting screen glare.


The PG48UQ delivers a seamless, tear-free gaming experience by enabling variable refresh rate technology as a default on NVIDIA GeForce® graphics cards.



The PG48UQ 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. Two USB ports 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.

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.


ASUS GameVisual technology has seven pre-set display modes to optimize visuals for different types of content. This unique feature can be easily accessed through a hotkey or the on-screen display settings menu.

ASUS Flicker Free technology

TÜV Rheinland-certified ASUS Flicker Free technology eliminates flicker, ensuring comfortable viewing experiences. This technology helps minimize eyestrain and other ailments typically associated with extended hours of viewing.

ASUS Low Blue Light technology

The new hardware-based ASUS Low Blue Light technology reduces potentially harmful high-energy blue-light emissions while offering color performance that's better than monitors with software-based filtering solutions.
