Triple-monitor KVM for three computers
The SMA 303 KVM switch lets one keyboard and mouse control three PCs while sharing three HDMI monitors and four USB 3.0 peripherals. It supports both extended and mirrored display modes for flexible multi-screen workflows. The unit ships with a 12 V power adapter, a wired remote, three USB 3.0 cables and a user manual.
Needs dual-DP and HDMI outputs on each PC
Each connected computer must provide two DisplayPort outputs and one HDMI output to drive the three monitor ports. The switch contains three independent circuit boards labelled A, B and C so inputs map directly to matching outputs; signals cannot cross between boards. Front-panel push buttons and the wired remote give instant PC selection without software.
Handles 8K at 60 Hz and high-refresh 4K
Maximum video performance reaches 8K at 60 Hz, with backward compatibility for 4K at 144 Hz, 4K at 120 Hz and 1080p at 240 Hz. USB 3.0 ports deliver up to 5 Gbps for fast peripheral transfers. Builders needing more than three computers or monitors, or systems lacking the required dual-DP plus HDMI graphics layout, will need a different solution.

Questions about this item
What resolution limit appears first when pushing this 303 KVM switch continuously at 8K 60 Hz?
The 8K 60 Hz ceiling is the first hard limit; higher refresh rates at that resolution are not supported by the switch itself.
How much heat or fan noise does the 303 produce when running three 4K 120 Hz monitors all day?
The unit has no fan and draws power from a 12 V adapter, so it runs silently with only modest warmth during extended use.
Which video ports must each computer already have to drive three HDMI monitors through this switch?
Every source PC needs two DisplayPort outputs and one HDMI output to match the switch’s input layout.
