A single-cable connection manages power and video simultaneously, so you can set up a complete multi-screen environment in seconds, anywhere.

• Super-Large 18.5" IPS Display — 18.5-inch IPS panel with 1920x1080 Full HD resolution and 16:9 aspect ratio; high-clarity picture quality for detailed charts, documents, and media.
