Fast 120HZ Refresh Rate

ROG Strix XG438Q offers an ultrafast 120Hz refresh rate, ensuring that even the fastest-paced games played at the highest visual settings remain buttery-smooth and completely lag-free.

Radeon FreeSync 2 HDR for smooth gameplay

ROG Strix XG438Q features freesync 2 HDR technology that delivers buttery-smooth visuals with low latency and better brightness and contrast. freesync 2 stipulates low-latency processing for both standard and HDR content, eliminating the input lag typically associated with HDR content.

High Dynamic Range (HDR) with DCI-P3 90% and DisplayHdr 600

ROG Strix XG438Q supports HDR technology across a range of luminescence (up to 750cd/m2) to deliver a wider colour range and higher contrast than traditional monitors. The brightest whites and the darkest blacks bring out details like never before. ROG Strix XG438Q also delivers DCI-P3 90% colour gamut and contrast performance that meets the requirement for DisplayHDR 600 approval.

Shadow Boost Technology

ASUS Shadow Boost technology clarifies dark areas of the game world without overexposing brighter areas, improving overall viewing while also making it easier to spot enemies hidden in dark areas of the map.

Multiple Hdr modes

Now you can choose from multiple HDR modes in order to adjust monitor HDR performance based on the current scenario.

Flicker-Free Technology

ROG Strix XG438Q reduces on-screen flicker to minimise eye strain, providing a more comfortable gaming experience.

Remote control

ROG Strix XG438Q comes with a remote control that lets you adjust display settings — such as brightness, contrast and the input signal — from a distance.
