Widescreen Picture and True-to-Life Colours
The 21:9 format combined with the Ultra Wide QHD resolution provides an expansive workspace for displaying multiple applications simultaneously without constantly switching windows. IPS technology displays consistent colours and maintains their accuracy from wide viewing angles up to 178° horizontally and vertically. The monitor covers 99% of the sRGB colour space, which is important for working with graphics and photos. The ZeroFrame design with thin bezels is non-distracting and simplifies setting up multiple monitors side-by-side for an even larger workspace.
Image Smoothness
The 75Hz refresh rate along with a 1ms (MPRT) response time contributes to a smooth display of fast-moving scenes. AMD FreeSync and VESA AdaptiveSync technologies synchronise the refresh rate of the monitor with the graphics card, eliminating tearing and stuttering during gaming. The VESA DisplayHDR 400 standard, combined with 400cd/m² brightness and high contrast, brings both light and dark parts of the scene to life. This makes the image look more realistic when watching movies or playing games with HDR content support.
Ergonomics and Eye Protection of the Acer CB342CU Monitor
The monitor stand offers flexible adjustment options to find the right working position. You can adjust the screen height or rotate it 90° to a vertical position using the Pivot function, which you will appreciate when working with long documents or code. To protect your eyesight during prolonged use, the integrated Acer BlueLightShield and Flicker-Free technologies reduce blue light emission and flickering. The monitor offers a 100 × 100mm VESA mount for wall mounting and includes integrated speakers with a total output of 6W for basic audio.
Connectivity Options
The monitor functions as a docking station thanks to its advanced connectivity. The main role is played by the USB-C port, which transmits the video signal, data and simultaneously powers the connected laptop with up to 65W. This solution keeps your desk tidy without unnecessary cables. The presence of an RJ-45 (LAN) port further extends the laptop's connectivity with a stable wired internet connection. To connect other devices, the monitor offers a wide range of ports.

Colour Coverage (Gamut)
Determines how accurately a monitor can display colours. sRGB is ideal for the web, movies, or games. DCI-P3/Adobe RGB is appreciated by graphic designers or professionals at work. The higher the value, the better the monitor displays colours. Maximum Brightness
Given in nits or cd/m², this value determines the brightness level of the monitor. 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
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
