Display and Colour Performance
The display uses a 44.5" VA panel with an ultrawide 32:9 aspect ratio and a 1500R curvature. This design surrounds your field of view and provides a panoramic view without needing to turn your head. The Dual QHD 5120 × 1440 pixel resolution provides a workspace equivalent to two 27" QHD monitors side-by-side, but without the distracting central bezel. VA technology is demonstrated by a high static contrast ratio of 3,000:1, which is the foundation for deep black shades. The 8-bit panel covers 100% of the sRGB colour space. Support for the HDR 400 standard, along with a brightness of 450 cd/m², improves the rendering of details in both light and dark parts of the scene.
Motion Fluidity and Gaming Features
The high 165Hz refresh rate supports smooth motion rendering when scrolling content quickly and when gaming. The screen redraws the image 165× per second, which reduces lag and provides a distinct advantage in dynamic scenes. A response time of just 0.8ms (MPRT) actively limits motion blur and ghosting. This parameter is key for image clarity during fast camera movements. The monitor includes Adaptive Sync FreeSync technology, which synchronises the refresh rate with the graphics card's output. This effectively suppresses screen tearing and stuttering for a seamless visual experience.
Ergonomics
The monitor stand supports an ergonomic workstation setup. It offers height adjustment within a 130mm range and the ability to tilt the screen to find the optimal position. These adjustments help maintain correct posture and reduce strain on the cervical spine during long workdays. For alternative wall or adjustable arm mounting, VESA 200 × 100 mounting points are provided. The monitor includes technologies for eye protection. The Flicker-free function reduces invisible backlight flickering, and the blue light reduction mode lowers the emission of this spectrum component to reduce eye fatigue.
Connectivity Options
The monitor acts as a central docking station in your workspace and simplifies cable management. An integrated KVM switch allows you to control two connected computers with a single set of keyboard and mouse, switching between devices directly through the OSD menu. Laptop connection is simplified by a USB-C port with 90W power delivery, which transmits the video signal, data, and simultaneously charges the device with a single cable. In addition, the built-in RJ45 port provides the laptop with a stable wired network connection. A hub with three USB 3.2 ports is available for connecting additional peripherals. The connectivity is complemented by a DisplayPort 1.4 and two HDMI 2.1 ports. The connector set includes modern ports for connecting computers, gaming consoles, and peripherals. HDMI, DisplayPort and USB-C cables are included in the package.

Colour Gamut
Determines how accurately the monitor can display colours. sRGB is ideal for web, films or games. DCI-P3/Adobe RGB will be appreciated by graphic designers or professionals. The higher the stated value, the better the monitor displays colours. Maximum Brightness
The value given in nits or cd/m² determines the monitor's brightness level. A brightness above 400 nits is key for HDR content and readability in sunlight, while standard office monitors are sufficient with values above 250. Refresh Rate and Response Time
Refresh rate (Hz) determines the number of frames displayed per second, so the higher the value, the smoother the picture and the less eye strain. A lower response time value (ms) eliminates motion blur. 144Hz+ is ideal for gaming, values around 75Hz are suitable for office monitors.Specifications
