All-encompassing experience: The 1900R screen curvature creates a wider field of view, minimizes reflection and offers near uniform visual focus, for a more comfortable
visual experience over extended viewing periods. Plus, the built-in, dual 5W speakers deliver great sound.

Unparalleled focus: Get incredible depth, breadth and a wrap-around view that helps you focus on your work. With IPS technology, you can expect consistent color and picture quality across a wide 178° viewing angle.
Enhanced color coverage

Enhanced color coverage

With 95% coverage of the DCI-P3 color space (which typically offers nearly 25% more coverage than sRGB), DCI-P3 is quickly becoming the color standard for creating and viewing content.

Accurate color, out of the box: Your monitor is factory calibrated at 99% sRGB to an accuracy of Delta-E less than 2 for accurate colors right from the start.

Your productivity hub

Connect to productivity: With options including RJ45 and USB-C®, your monitor serves as a productivity hub that delivers stable Ethernet and up to 90W of power delivery—all in a clutter-free setup.

Enhanced manageability: MAC Address pass-through , PXE Boot, and Wake-on-LAN are conveniently built in.

Multitask efficiently: Connect two PC sources to the monitor. Our intelligent Auto KVM feature detects the latest connected PC and seamlessly switches controls over. View content from both PC sources with Picture-by-Picture (PbP) and Picture-in-Picture (PiP), and use the KVM (keyboard, video and mouse) feature control both PCs with a single keyboard and mouse.
