Share keyboard, mouse, and DisplayPort display between four HD multimedia systems

The SV431DPUA 4 Port USB DisplayPort KVM Switch with Audio combines next generation display standards with seamless KVM control of up to 4 connected PC or Mac computers.

Featuring DisplayPort resolutions of 2560x1600 @60Hz, as well as offering both 7.1 HD digital audio (with supporting displays and sources) and separate 3.5mm stereo audio support. An integrated USB 2.0 hub allows you to share 2 additional peripherals among attached computers as if they were directly connected.

Suitable for high quality static imaging applications such as health care (MRI, X-ray diagnostics, etc.), a maximum resolution of 3840x2400 is supported at reduced refresh rates.

A simple yet comprehensive solution, the 4-port KVM features both front-panel push-button and hotkey switching, and offers a small form factor with rear connection ports, to minimize workspace disruptions.

Backed by a StarTech.com 3-year warranty and free lifetime technical support.

Rackmount your KVM switch

If you’d like to mount this KVM switch to your server rack, StarTech.com offers a 1U Rackmount Bracket (sold separately) that turns this KVM into a rackmountable KVM.

The StarTech.com Advantage

- USB peripheral sharing using the integrated hub eliminates the expense of duplicate devices (printers, scanners, etc.)
- Compatible with Mini-DisplayPort adapters, making it suitable for Apple Macbook connectivity
- Support for digital DisplayPort 7.1 HD audio or separate 3.5mm analog audio connections for added versatility

14 days from date of receipt, or expected date of receipt on non-tracked items.
