Control four DP computers using a single console with a built-in USB 3.0 hub for sharing additional peripheral devices

This 4-Port USB 3.0 DisplayPort KVM switch lets you control four DisplayPort (DP) computers with a single monitor, keyboard and mouse. The KVM also features 3.5 mm audio and a built-in 3-port USB 3.0 hub.

Convenient and cost-effective USB 3.0 peripheral sharing

This KVM switch offers a built-in 3-port USB 3.0 hub that's separate from your HID keyboard and mouse, so you can share USB peripheral devices between each connected computer and avoid the expense of separate equipment. The USB 3.0 hub automatically switches your connected USB devices to the selected computer, saving you the hassle of disconnecting and reconnecting your peripherals.

With support for USB 3.0, you can achieve data transfer rates up to 5Gbps, to ensure flawless performance for your USB peripherals - great for quickly transferring data to external USB 3.0 drives.

Astonishing picture quality

Offering support for resolutions up to Ultra HD 4K at 30 Hz, this 4-port DisplayPort KVM switch has the ability to drive large DP displays with ease, making it ideal for graphical applications that require high-resolution video support.

Complete multimedia control

The KVM switch features auxiliary 3.5 mm audio ports that enable you to share independent analog audio, from each of your connected computers, with your desktop speaker set. Independent audio, along with 4K DP video, gives you full multimedia control between different computers, making this KVM perfect for creative professional applications such as video and sound design or editing.

The SV431DPU3A2 is backed by a StarTech.com 2-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.
