Quad HD 180Hz display
The monitor screen has a curvature radius of 1500R and supports a maximum resolution of Quad HD - 2560 × 1440 pixels. The high refresh rate of the panel, reaching 180 Hz, ensures smooth display of moving objects. The response time is only 1 ms (GtG) and 0.5 ms with the use of MPRT technology, which makes the model ideal for dynamic games.
Excellent color rendering
With the help of the proprietary G-Menu software, you can customize the display of the crosshair in the center of the screen and the fps counter in the upper corner. To improve visibility in dark scenes, a function for brightening shadow areas is provided. The color rendering is impressive: the screen covers more than 127% of the sRGB space and about 93% of the DCI-P3 color model, providing realistic and saturated colors.
Free space on the table
The monitor features DisplayPort v 1.4 and two HDMI v 2.0 ports, as well as a 3.5 mm audio output for wired headphones. The compact stand minimizes the space occupied on the desktop, but has limited adjustment options. For users who prefer individual adjustments, compatibility with VESA 100x100 mm wall brackets is provided.
