## Long description

The iiyama G-MASTER 45" curved 32:9 Dual QHD monitor features a 45" (114.3 cm) VA panel with a 5120 x 1440 resolution, 165 Hz refresh rate and 0.8 ms response time. The 1500R curvature and wide 178° viewing angles deliver an immersive image with high contrast and vivid colours. Integrated USB-C docking with power delivery, a built-in USB hub and RJ45 (LAN) simplify connectivity, while the KVM switch lets you control two computers with a single monitor, keyboard and mouse. The matte screen surface and height-adjustable stand support comfortable long-term use.
Advantages
Ultra-wide Dual QHD resolution provides a large, continuous workspace suitable for multitasking and detailed image work. The VA panel offers high contrast and deep blacks compared with TN panels, and the 1500R curve reduces visual strain while enhancing immersion. USB-C docking consolidates power, video and network over one cable, and the built-in KVM switch allows seamless switching between two PCs without reconnecting peripherals. The height-adjustable stand and anti-glare surface improve ergonomic comfort.
Suitable for
Multitasking and productivity (multiple windows, spreadsheets, documents)
Content creation and video/photo editing requiring wide timelines
Simultaneous work and personal PC setups using KVM
Immersive gaming on a curved ultra-wide display
Office use with wired network connection via RJ45

How to use
Connect your laptop or PC using the USB-C port to provide video signal, network access and power through a single cable. Alternatively, use the available video inputs and RJ45 for a wired network connection. Attach keyboard, mouse and other USB peripherals to the monitor’s USB hub so they remain connected when switching between computers. Use the on-screen display (OSD) menu to select input sources and operate the KVM switch to change control between two connected systems. Adjust the monitor height for an ergonomic viewing position.
Usage recommendations
For long sessions, set the monitor height and viewing distance so the centre of the screen sits at or slightly below eye level; enable a comfortable refresh rate and reduce ambient glare to minimise eye fatigue. When using USB-C docking, confirm your laptop supports USB-C power delivery and DisplayPort over USB-C for full functionality.
