iiyama ProLite XCB4994DQSU-B1 49-inch DQHD 120Hz Monitor
A continuous 49-inch Dual QHD workspace for side-by-side tasks
The iiyama ProLite XCB4994DQSU-B1 combines a 49-inch, 32:9 VA panel with 5120×1440 Dual QHD resolution. The wide desktop offers the pixel workspace of two QHD screens without a central bezel, while the 1000R curve brings the edges around the viewing position. A 130mm height adjustment, USB hub and built-in stereo speakers support a practical business workstation.
What's in the Box

What It Means in Practice
- Arrange applications side by side on a 32:9 desktop or use PiP/PbP with compatible connected sources.
- Choose a graphics output and cable that explicitly support 5120×1440 at the intended refresh rate; adapters may impose lower limits.
- Connect the USB Type-B upstream link for the four-port peripheral hub; Type-A and Type-C downstream power ratings are 4.5W and 7.5W per port.
- Adjust height and tilt to suit the workstation, and allow enough desk depth for the 356mm stand footprint.
What Will Not Work
- USB-C downstream ports do not establish USB-C video input, high-power laptop charging or Ethernet docking.
- Native120Hz requires DisplayPort; native HDMI refresh is limited to 60Hz.
- HDR10 signal support does not establish a certified DisplayHDR tier or local dimming.
- The manual identifies desktop use and does not guarantee 24/7 operation in all environments.

Frequently Asked Questions
Plan this monitor around the width of the workspace and the graphics connection. A 49-inch Dual QHD desktop can replace two QHD viewing areas, but native 120Hz needs the correct DisplayPort output. Its USB-C sockets are peripheral connections rather than evidence of a full laptop dock.
