Panel, Resolution and Surface
The 27-inch Fast IPS screen combines a 2560 × 1440 resolution and an anti-glare surface. ASUS lists 97% DCI-P3 color space, 10-bit display colors and VESA DisplayHDR 400 certification. The 16:9 format and QHD pixel count provide a familiar desktop layout for a setup that needs detailed images alongside a high-refresh gaming mode.
Refresh Modes and Response Time
The maximum 255 Hz setting is an overclocked mode, with a specified 1 ms gray-to-gray response and a separate 0.3 ms minimum figure. The published signal ranges list up to 255 Hz across HDMI, DisplayPort and USB-C. Configure a compatible source for the intended resolution and refresh rate, then confirm the selected setting in your operating system.
Motion Settings for Compatible Systems
Adaptive-Sync support works with compatible graphics hardware, while ASUS ELMB Sync combines its motion-blur reduction feature with variable-refresh operation in supported modes. These are settings to configure around your system and game. Review the available display options after choosing the resolution and refresh rate, then compare the motion settings using the games you normally play.
Connections for Your Desk
One DisplayPort 1.4 input, one HDMI 2.1 input and USB-C with DisplayPort Alt Mode give you several compatible video connection choices. USB-C supports 15 W Power Delivery, and an earphone output is included in the specifications. Review the power and signal requirements of the source device when deciding how each system will connect to the display.
Position the Screen Around You
The stand offers up to 110 mm of height adjustment, tilt and swivel up to 45° in each direction. Pivot adjustment is also listed for changing the screen orientation. A 100 × 100 mm VESA mounting pattern provides an alternative when using a suitable mount. Check the published dimensions and weight when planning the screen position and available desk space.
Display Controls and Daily Setup
GamePlus, GameVisual and Shadow Boost provide gaming-oriented display adjustments. DisplayWidget Center gives software access to supported settings, complementing the monitor’s on-screen controls. Use the available picture modes as a starting point, then adjust the image for the game, room lighting and everyday desktop work that share the same display.
Plan the Display and the Rest of Your Desk
Compare resolution, refresh rate, screen size and the input you will actually use. Match the computer or console output to the chosen display mode, and leave room for the monitor stand and mouse movement.
