Dual-computer HDMI KVM switch

This HDMI KVM switch lets one keyboard, one mouse and up to two monitors control two computers. It is aimed at users who need to operate separate systems side by side without duplicating input devices. The unit accepts four HDMI inputs and delivers two HDMI outputs for extended or duplicated desktop layouts.

Driver-free switching and USB 2.0 hub

The box includes hot-key, mouse-gesture, front-panel button and automatic scan modes with an adjustable interval between 8 and 999 seconds. No software installation is required on Windows 10, 8.1, 7, XP, Vista, Mac OS, Linux or Chrome OS. A built-in USB 2.0 hub also shares peripherals such as a headset, microphone, webcam or external drive between the connected PCs.

4K@30Hz limit and dual-HDMI requirement

Video is capped at 4K@30Hz and only appears when both the source and the display support that rate; otherwise the signal falls back to 1080P. Each computer must provide two HDMI outputs, so laptops with a single HDMI port need reliable adapters for VGA, DVI, USB-C or DisplayPort sources. The supplier notes that vertical mounting helps prevent cable strain on the HDMI connectors.

Questions about this item

Does the KVM switch require firmware updates or driver maintenance over time?

No firmware or driver updates are required; the unit is driver-free and operates via hot-key, mouse or automatic scan switching.

What limits continuous operation when running two 4K sources at 30 Hz?

The HDMI 4K@30Hz bandwidth ceiling is the first limit; both computers and both monitors must support 4K@30Hz to sustain that resolution.

How much heat or fan noise does the switch produce during all-day use?

The device has no fan and draws minimal power, so it runs silently with only slight warmth during extended sessions.
