Evaluation of key product features

Thanks to its large 31.5-inch surface and 4K UHD resolution, the monitor stands out with a crystal-clear image and exceptional sharpness of detail, which is crucial when playing games, watching movies or working with multiple windows. VA panel technology provides high contrast and rich colors, which is especially evident in dark or color-intensive scenes and allows comfortable viewing from different angles without color distortion.

Integrated KVM functionality lets you control two devices with a single keyboard and mouse, perfect for dual-PC or hybrid work environments. The USB-C port supports up to 95W of power delivery, so you can easily connect a laptop and power it directly through the monitor, ensuring a tidy and efficient workstation without unnecessary cables.

With a refresh rate of 144 Hz and an extremely short response time of 1 ms, it provides a fluid and smooth experience in fast-paced gaming action, without blurring. The high brightness of 400 cd/m² ensures a clear image even in brighter rooms. With an aspect ratio of 16:9 and a matte black surface, the monitor is suitable for both home and professional use, while reducing reflections and eye fatigue during prolonged use.

For users who demand performance, precision, and modern connectivity solutions, this model is an excellent choice, combining cutting-edge technology with advanced usability and flexibility for a wide variety of needs.

It is important to know

When choosing a 32-inch 4K monitor like this one, it's important to understand its role in multitasking and display quality, as well as the practical limitations of placement and connectivity. Pay special attention to the combination of screen size, resolution, and aspect ratio, as well as device connectivity, before making a purchase.

• For larger monitors like a 31.5-inch 4K display, proper viewing distance and a deep enough desk are essential for comfort during extended use – placing it too close can reduce visibility and comfort.
• The combination of 4K resolution and a larger diagonal allows for sharp text and more space for open windows, which is an advantage when doing analytics, programming, or editing documents.
• A monitor with a USB-C port and KVM function is suitable for users who frequently switch between two computers, but before using USB-C, check the actual video output support on your device.
• The 144 Hz refresh rate is useful for smoother scrolling and more fluid display of fast movements, which will be especially appreciated by users who want to combine work and gaming.
• The use of a VA panel offers good contrast and black depth, but may be slightly worse during fast movements or intensive text work for users sensitive to so-called ghosting.

In practice

🟢 Multitasking office use

Very suitable – large working area, high resolution and fast connections suit demanding workflows with multiple windows or spreadsheets open at the same time.

🟢 Analytics, programming and BI usage

Very convenient – 4K resolution and large diagonal allow you to display large amounts of data, visualizations, and more code at the same time without the need to constantly scroll or switch windows.

🟢 Gaming and fast graphics refresh

Very convenient – 144 Hz refresh rate and responsive connectivity allow for smoother gameplay and better display of fast movements in games or videos.

🟡 Switching between two computers (KVM)

Suitable with limitations – a quality KVM function makes it easy to use two devices, but for smooth operation, it is essential to check the support of USB-C connection with video output on both devices.

🟡 Long-term reading of texts on a white background

Decent with limitations – the VA panel offers good contrast, but sensitive users may encounter visible ghosting when quickly scrolling through longer documents.
