21.5" Acer KA222QE0bi
The Acer KA222QE0bi monitor brings a 21.5" IPS panel with a Full HD resolution of 1920 × 1080 pixels to your desk, displaying sharp details for both work and entertainment. This Acer office monitor supports a refresh rate of up to 100Hz when connected via HDMI, which results in smoother cursor movement and scrolling. For older devices, it offers a VGA input with a 100Hz frequency. The 1ms (GtG) response time reduces blur in fast-paced scenes. The ZeroFrame design with its thin bezels creates an almost borderless look and makes it easy to combine multiple screens into one seamless surface. The colour spectrum covers 99% of the sRGB space, contributing to accurate colour reproduction.

Smooth Visuals and Eye Protection
AMD FreeSync technology synchronises the monitor's refresh rate with the graphics card's output, effectively reducing screen tearing and stuttering when playing games or watching videos. To protect your eyes during long-term use, the monitor is equipped with the Acer VisionCare suite of technologies. The Flickerless feature reduces invisible backlight flicker, which causes eye strain. The BlueLightShield blue light filter reduces emissions of potentially harmful blue light, while ComfyView with its matte surface and Low Dimming reduce glare and adjust brightness in dark rooms.
True-to-Life Colours and Precise Adjustment
At the heart of the picture is an IPS panel with a 10,000:1 contrast ratio and 250cd/m² brightness, which provides consistent colours and wide viewing angles. The panel covers 99% of the sRGB colour space, which contributes to faithful colour reproduction for graphic design or photo editing. For users who demand complete control over the image, the monitor offers six-axis RGBCMY colour adjustment. This feature allows you to independently adjust the hue and saturation of red, green, blue, cyan, magenta, and yellow to achieve precise calibration.
Design and Flexibility
The ZeroFrame design with its minimal bezels not only modernises the look of the monitor but also makes it easier to set up multiple screens side-by-side to expand your workspace without distracting transitions. Workplace ergonomics are supported by a stand that allows the screen to be tilted from -5° to +25°. This lets every user adjust the viewing angle to their needs. For more placement options, the monitor supports the VESA 100 × 100mm standard, so it can be easily mounted on a wall or an adjustable arm to free up desk space.
Connectivity Options
A modern HDMI 1.4 port and an older analogue VGA (D-Sub) connector are used for connecting to a computer or other devices, ensuring wide compatibility. Connecting via HDMI supports the full 100Hz refresh rate. The connector set also includes a headphone output and a microphone input, which centralise the connection of audio peripherals directly on the monitor, simplifying cable management on your desk.

Colour Coverage (Gamut)
Determines how accurately the monitor can display colours. sRGB is ideal for the web, films, or games. DCI-P3/Adobe RGB is appreciated by graphic designers or professionals at work. The higher the stated 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 above 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 value (ms) eliminates motion blur. 144Hz+ is ideal for gaming, while values around 75Hz are suitable for office monitors.Specifications
