IPS technology for true-to-life colours
The IPS panel displays colours with high accuracy and maintains consistent brightness from all viewing angles. The viewing angles are 178° both horizontally and vertically. The iiyama 23.8" ProLite displays a stable image without colour distortion when viewed from the side. Users working with graphics or documents can rely on a stable visual output.
High 120Hz refresh rate
The 120Hz refresh rate speeds up image redrawing and reduces motion blur. A 1ms response time contributes to sharp detail rendering. This iiyama ProLite monitor delivers smooth, tear-free motion when scrolling through pages and watching videos. The smooth motion increases comfort during long periods of working with text.
High contrast
A native contrast ratio of 1500:1 reveals subtle differences between dark and light shades, while the advanced contrast is rated at 80M:1. The sRGB colour coverage is 96% and the colour depth is 8-bit for displaying 16.7 million colours. The screen renders deep shadows and bright details with a brightness of 350cd/m². The pixel size is 0.275mm and contributes to display sharpness. This gives graphical content the depth and fidelity it needs. The stand offers 150mm of height adjustment to find the optimal eye position relative to the screen surface. Correct height adjustment helps prevent neck and back fatigue during long workdays. Users can easily adjust the height to suit their stature and workstation layout. The stable base holds the monitor firmly on the desk, and an integrated cable management system helps keep the workspace tidy.
Rotate the screen to portrait mode
The pivot function rotates the screen 90° into portrait mode for working with long text documents, spreadsheets, or programming code. The stand also offers a full 360° rotation, 180° to the left and 180° to the right, which simplifies sharing content with colleagues. The design supports tilting 23 degrees up and 5 degrees down to reduce light glare. Adjusting the position requires no force and helps maintain a healthy posture.
Eye protection with eye-care technologies
Flicker-free technology eliminates the invisible flickering of the LED panel's backlight at all screen brightness levels. The integrated blue light filter lets you reduce the emission of the harmful colour spectrum using a software setting. The monitor helps protect your eyesight during long shifts in the office or when studying at night. Your eyes stay less tired even after several hours of continuous screen viewing.
Low energy consumption
Energy class C signifies high operational efficiency and low electricity costs. Typical consumption in SDR mode is 12W, corresponding to a consumption of 12kWh per 1000 hours of operation. In standby mode, consumption drops to just 0.5W, and in off mode it is only 0.3W. The internal power supply operates at a voltage of 100 to 240V at a frequency of 50/60Hz. The low heat generation also extends the lifespan of the internal components.
Connectivity options
On the back of the monitor, there are graphics inputs for connecting to computers, laptops and other devices. HDCP technology is supported for transmitting protected content. You can also plug headphones directly into the monitor. A Kensington lock slot is provided for security. A 1.5-metre power cable and an HDMI cable of the same length are included in the package. The four-sided thin bezel design makes it easy to create a panoramic workspace with multiple screens side by side. The 100 × 100mm VESA mount is used for mounting on a wall or a mechanical arm. The width of the monitor is 539mm and the height with the stand varies from 374 to 497mm.

Colour gamut
Determines how accurately the monitor can display colours. sRGB is ideal for the web, films or games. Graphics designers or professionals will appreciate DCI-P3/Adobe RGB. The higher the value, the better the monitor displays colours.
Maximum brightness
The value, given in nits or cd/m², determines the brightness level of the monitor. A brightness of over 400 nits is key for HDR content and readability in sunlight, while standard office monitors are fine with values above 250.
Refresh rate and response time
The 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 (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
