Multi-screen setup for a panoramic workspace
Connect multiple ultra-slim bezel monitors to create a panoramic workspace, keep your apps in view, streamline multitasking, and boost productivity.
Reduced eye strain & fatigue
Work, study or play for longer with greater visual comfort. The Blue Light Reducer feature lets you lower blue light emissions through software settings, helping minimise eye strain during extended screen time. Combined with flicker-free technology, it supports a more comfortable viewing experience so you can stay focused throughout the day.
Save electricity, maintain picture performance
Compared to a C Energy class monitor of the same size, your C label iiyama display reduces energy costs by around 37%! Without sacrificing picture quality. The efficient LED backlight technology combined with a high-performance colour filter keeps brightness and colour vibrancy intact, ensuring your viewing experience stays exactly as it should be. And with lower power consumption, you're also reducing your environmental footprint.
Built-in audio without extra clutter
Enjoy clear, pleasant sound for calls, videos, and music while keeping your desk free of extra speakers, thanks to the integrated audio.
Reveal hidden details with deeper contrast
With a native contrast ratio of 1500:1, this monitor brings out subtle shadow nuances and fine tonal transitions. You see more image information at a glance, making it easier to make precise creative choices during editing and colour grading. Dark areas stay crisp and distinct without blending into one another.

FAQs
Yes, Adaptive Sync is compatible with AMD FreeSync and NVIDIA G-Sync.
MBR cannot be selected when FreeSync/AdaptiveSync is activated, because MBR can interfere with the FreeSync/Adaptive Sync technology as they have different methods of improving motion clarity. MBR reduces motion blur (response time), while Adaptive Sync/FreeSync addresses stuttering. We recommend activating Adaptive Sync/FreeSync on systems with fluctuating or unstable frame rates. MBR performs best on powerful systems that maintain a consistently high frame rate.
If your monitor is displaying a "No Signal" message, please check the following:
1. Ensure the cables are properly connected at both ends.
2. Select the correct signal input (HDMI/DP) or choose AUTO.
For guidance on selecting an input while the screen is in standby mode, please consult the user manual. On desktop monitors, common methods include pressing the INPUT, AUTO, or "2" buttons, or moving the joystick backward.
Yes, your iiyama monitor will work with your Apple Mac system. However, it depends on the signal input how to connect. Since Apple Mac systems from 2020 onwards only have Thunderbolt 3 (USB-C) ports for video output, you have two options:
1. Connect directly to the USB-C signal input on your iiyama monitor.
2. In case your monitor only has HDMI or Displayport, you will need a Mac-compatible dongle that supports one of the video inputs available. Apple offers a USB-C Digital AV Multiport Adapter (MW5M3AM) that can be used for this purpose.
3. If your iiyama monitor has touchscreen capabilities, please refer to the user manual to verify touch functionality compatibility with your Mac system.
To resolve the issue of a blinking picture, please follow these steps:
1. Inspect the Signal Cable.
Ensure the signal cable is securely connected at both ends and free from any physical damage. Avoid any sharp bends or squishing of the cable.
2. Use a Shorter Cable.
If possible, use a cable shorter than 3 meters and connect the monitor directly to a wall power socket, avoiding the use of adapters.
3. Disable FreeSync/Adaptive Sync.
For desktop or gaming monitors, try disabling FreeSync or Adaptive Sync in the monitor's settings menu.
