Product information

Description

The U27G4R Dual-Frame Monitor lets you switch between UHD at 160Hz and FHD at 320Hz to match your needs for gaming or content creation. It uses a Fast IPS panel with 1ms GtG and 0.5ms MPRT response times, supports HDR400 and AdaptiveSync for smooth visuals, and includes HDMI 2.1 for modern connectivity. The monitor’s ergonomic eSports base is designed for comfortable long sessions and flexible positioning.

Advantages

Switchable resolution and refresh-rate modes provide flexibility for high-detail work in UHD@160Hz or ultra-high refresh competitive play in FHD@320Hz. Fast IPS technology combined with 1ms GtG and 0.5ms MPRT minimizes motion blur and ghosting. HDR400 increases dynamic range for brighter highlights, and AdaptiveSync helps eliminate screen tearing. HDMI 2.1 ensures compatibility with current consoles and PCs that require high bandwidth.

Key specifications

  • Screen modes: UHD (3840×2160) @160Hz; FHD (1920×1080) @320Hz
  • Panel type: Fast IPS
  • Response times: 1ms GtG, 0.5ms MPRT
  • HDR: HDR400
  • AdaptiveSync: supported (G-Sync to be confirmed)
  • Inputs: HDMI 2.1 (plus other standard inputs as available)
  • Stand: ergonomic eSports base

How to use

Select the desired display mode in the monitor OSD or via connected device settings to switch between UHD@160Hz and FHD@320Hz. Use HDMI 2.1 for maximum bandwidth when connecting modern consoles or graphics cards. Adjust brightness, HDR and AdaptiveSync options through the on-screen menu to suit content type. Position the ergonomic eSports base for comfortable viewing height and angle during long sessions.

Recommendations

For competitive gaming, use FHD@320Hz with AdaptiveSync enabled and a compatible GPU or console. For content creation or detail-oriented work, choose UHD@160Hz and enable HDR400 where supported. Ensure your source device and cables support HDMI 2.1 for full performance.

0.5ms MPRT - Moving Picture Response Time
MPRT stands for Moving Picture Response Time. MPRT technology temporarily controls the monitor backlight during frame changes. By reducing the time a frame is visible, "ghosting" and blurring effects are reduced, resulting in a smoother, more fluid gaming experience.
0.5ms MPRT - Moving Picture Response Time
1ms Response time GTG - Grey-to-Grey
GtG stands for Grey-to-Grey and indicates how long a pixel takes to change from one grey level to another. In gaming, every millisecond matters and can be the difference between landing or missing a shot. A fast response time also reduces ghosting and motion blur.
1ms Response time GTG - Grey-to-Grey
Fast IPS
Unlock your gaming potential with Fast IPS panels that offer rapid pixel response times down to 1ms GtG. Say goodbye to motion blur and enjoy sharper images that improve targeting precision and performance in fast-paced games. Fast IPS also delivers vivid colors and wide viewing angles for an immersive experience.
