Triple-monitor KVM for two PCs

The SMA 303DP KVM switch lets one keyboard, mouse and three DisplayPort monitors control two computers. It accepts three DP inputs per system and provides three DP outputs plus three USB 3.0 ports for shared peripherals. A wired remote and front-panel buttons give instant switching. An external power adapter is included.

Suited for dual-system desks needing three displays

Ideal for users who run two workstations — such as a work laptop and a personal tower — and want a single triple-monitor setup with shared USB 3.0 devices and audio. Not suited for setups where either computer lacks three DisplayPort outputs, or where only one or two monitors are required.

Handles 8K at 60 Hz and 4K at 144 Hz

Each channel supports up to 8K at 60 Hz when the graphics card, monitor and cable all meet the DP 1.4 spec; it also runs 4K at 144 Hz for high-refresh workflows. USB 3.0 ports deliver 5 Gbps bandwidth for fast peripheral transfers. The switch requires three DP cables per computer, so cable count grows quickly.

Questions about this item

What cables and ports must each computer already have to connect to the SMA 303DP?

Each computer needs three DisplayPort outputs and one USB-A 3.0 port to link to the three DP inputs and the USB-B upstream port on the switch.

Can I keep a 4K 144 Hz monitor on this switch while the other two run at 8K 60 Hz?

Yes, the switch is downward compatible with DP 1.2 and supports 4K at 144 Hz alongside higher-resolution displays.

How do I confirm the KVM is actively passing video and USB to the selected PC?

The front-panel LEDs light for the active computer, and the wired remote shows the same status; keyboard, mouse and all three monitors respond immediately after switching.
