45’’ Dual QHD VA panel with KVM switch, USB-C dock and RJ45 (LAN) and height adjustable stand
The XCB4594DQSN features a 1500R curved VA panel with a 165Hz refresh rate, 0.8ms MPRT, and a 5120x1440 (DQHD) resolution for superb image quality. The KVM switch allows you to connect multiple computers that can be operated over one console (monitor, keyboard, mouse). The USB-C dock simplifies setup with one cable for laptop signal transmission, power, and charging. Connecting to the Internet via LAN automatically links your notebook to the network. The VA panel ensures expansive viewing angles and vivid colours, and the 1500R curvature minimizes eye strain for a lifelike and fully immersive gaming experience. The dual QHD resolution provides sharp visuals, and the height-adjustable stand adds a comfortable and highly ergonomic experience.
Ultra-wide 32:9 monitors with a DQHD 5120x1440 resolution, also called dual QHD, deliver razor-sharp images. They make it possible to divide the workspace into multiple windows and simultaneously open all the documents you need.
The 1500R curvature of the screen reduces the strain on your eyes while providing a realistic viewing experience. It allows a comprehensive and more natural viewing angle than you’ll have with flat monitors lined up side by side. The result is a more immersive experience which boosts productivity and focus whether it be for work, gaming, entertainment, editing or more.
The dock allows you to connect your laptop with a single cable to the monitor to both make sure it is charged and connected to a wired network and signal from the laptop is sent to the monitor. With additional USB-ports, your mouse, keyboard or webcam can also be connected to the monitor. All thanks to a single cable connecting your laptop* to the USB C dock in the monitor.
*Functions vary depending on your laptop USB-C support.
Having a monitor with a KVM switch allows you to share the devices connected via USB to your monitor with two different PCs. Just change the signal input in the OSD menu of the monitor and your keyboard, mouse and webcam will switch from your work laptop to your gaming PC.
VA panel technology offers higher contrast, darker blacks and much better viewing angles than standard TN technology. The screen will look good no matter what angle you look at it.

To configure your 5K monitor to work as two QHD monitors, please refer to the guidelines provided in the attached document.
To resolve the issue of your laptop not charging, please try the following steps:
1. Activate USB BC or disable USB standby mode in the monitor’s settings menu.
2. Update your PC’s BIOS/UEFI.
iiyama monitors with USB-C Dock capabilities can be recognized by an "N" in their model names, such as HSN or QSN. For example, XUB****HSN. You can also visit our product selector page and use the available filters.
To explore the features and benefits of a monitor with a USB-C dock, please watch the video below.
To extend the desktop via DP-out, enable the MST function in the screen settings. For detailed instructions, please refer to your user manual.
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.
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.
