SmartAVI HKM-PROS (4 Computers / 3 HDMI + 1 Android Source / Multi-Source KVM Switch / Contact for Pricing) Review
The SmartAVI HKM-PROS is a 4-source KVM switch combining 3 HDMI computer inputs with 1 dedicated Android device input and 4K@30Hz support, priced on request.
This is a genuinely different use case from the rest of this batch - it's built for control rooms and digital signage setups where one console needs to switch between HDMI-connected PCs and a mounted Android media player or tablet on the same monitor, something none of the other switches here support.
A Fourth Port Unlike the Others
Where every other switch in this catalog treats all its ports identically, the HKM-PROS dedicates one input specifically to Android sources with touch pass-through, letting one console control both traditional PCs and an Android box or tablet.
Built for Mixed-Source Control Rooms
Digital signage operators and control rooms that run a mix of Windows/Linux computers and Android media players benefit from a single switch rather than juggling a separate KVM and a separate Android input selector.
Comparison to Alternatives
Versus the SmartAVI K304E-SH - a similarly SmartAVI 4-port HDMI switch, but built for long-distance console extension rather than mixed Android/PC sources. Versus the ATEN CS84U - a basic 4-port VGA switch with no Android input or 4K support. Versus the ADDERView Multi-Viewer (CCS-MV4224) - offers simultaneous multi-screen viewing but no dedicated Android input, a different feature set entirely.
