IOGEAR's 4-port Dual-Link DVI KVMP switch with 2.1 audio supports high-end 3D graphics support (NVIDIA® 3D Vision Ready), compatible with most gaming keyboards.

4-Port Dual-Link DVI KVMP Pro with 2.1 Audio

IOGEAR's 4-port Dual-Link DVI KVMP switch with 2.1 audio supports high-end 3D graphics support (NVIDIA® 3D Vision Ready), compatible with most gaming keyboards. The integrated 2-port USB 2.0 hub allows for peripheral sharing. Experience up to 2560 x 1600 video resolution on four computers and share multiple USB peripherals from a single keyboard, monitor, and mouse console.

EDID Support

This 4-Port DVI KVM switch features IOGEAR's DynaSync™* technology, enabling the KVMP to read and remember the monitor's optimal display (EDID) parameters and refresh rate. This is a critical function in today's graphic intense applications where large wide screen displays (up to 30") are required.

Convenient Switching Method

Switching between computers can be done in three convenient ways:

  1. Push button port selection located on the unit's front panel
  2. "Hotkey" combinations entered from the keyboard
  3. Mouse** port switching

High Video Resolution Solution

This powerful 4-Port Dual-Link DVI KVMP will increase efficiency and save equipment cost for applications where ultra-high video resolution, large or widescreen monitors are required such as:

  • 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.

4K UHD Resolution

Achieve 3840 x 2160 @30Hz 4K UHD Resolution with this Dual-Link DVI KVM Switch using IOGEAR’s 4K HDMI to DVI-D Converter Cable GHDDVIC4K3. With this reversible 4K cable, you may use 4K source and project to 4K monitors, without the need to upgrade your Dual-Link DVI KVM switch setup.

Increase Efficiency from One Workstation

The patented asynchronous switching allows the user to independently switch applications between the connected computers. You can run one application on one computer while running another application on the other. Moreover, the integrated 2-port USB 2.0 hub is available for each computer to share multiple peripherals connected to the hub or via an external powered USB 2.0 hub. Access to such peripherals is performed on a one-at-a-time basis.

2.1 Surround Sound

Share 2.1 surround sound audio between two computers. Connect powered desktop speakers for stereo sound and a single microphone for audio input/output to each computer.

Secure Access and Control

This 4-port KVM also offers a cost-effective solution to increase security by allowing users to switch between the Internet connected PC and an Intranet connected PC.
