IOGEAR's GCS1644 4-Port Dual View DVI KVMP Switch marks a leap in KVM functionality by combining IOGEAR's Display Emulation Technology with the widescreen graphics resolution of today's 30+ inch monitors, supporting Dual View / Dual Link DVI, 2560 x 1600 (higher than 1080p HD). Four Dual-View / Dual-Link display computers can be accessed and controlled from a single console running dual-displays! This unique KVMP can increase efficiency and save equipment cost for applications where high resolution, dual-display large or widescreen monitors are required: - CAD (Computer Aided Design) and CAM (Computer Aided Manufacturing) - Desktop Publishing / Graphic Design / Video Editing - Medical / Surgical / Diagnostic Displays - And High-End Gaming, where high and ultra-high video resolution is demanded. The GCS1644 also features two USB 2.0 peripheral ports for asynchronously sharing USB devices between your computers. A powered USB hub may be attached to the peripheral ports for added functionality. Audio and microphone support makes sharing speakers and a microphone a convenience for the users which serves as an extra value. The IOGEAR's Display Emulation Technology* remembers your monitor's ideal resolution and refresh rate (EDID), making it possible to boot all your computers simultaneously, switch back and forth between computers, and still maintain the ideal video settings of the monitor. The GCS1644 offers an out-of-box solution including all cabling required for “Set-up and Go”!
