4-in-1 HDMI Multi-Viewer

The Vszerda quad multi-viewer connects four HDMI sources to a single display. It suits security monitoring, gaming consoles, PCs and streaming devices that need simultaneous viewing or quick switching without cable swapping. The unit includes an IR remote and a front button for mode changes.

Passive Cooling and Low Power

The compact aluminium enclosure runs without a fan, so operation is silent. A supplied DC adapter powers the switch, drawing minimal current while handling 4K@30Hz or 1080P@60Hz signals. No active cooling means zero noise in living-room or office settings.

Desktop Footprint and Mounting

At 1.18 x 1.97 x 3.94 inches and 11.3 ounces the box sits unobtrusively on a shelf or can be taped behind a monitor. Four HDMI inputs and one output use standard connectors, so existing cables plug straight in. Buyers needing more than four sources or 4K@60Hz passthrough will need a different solution.

Questions about this item

How do I connect the four HDMI sources and the display to this 4x1 quad multi-viewer, and what step is often missed?

Connect each of the four HDMI sources to the four input ports, connect the display to the single HDMI output, then plug in the included DC power adapter; the step often missed is powering the unit before expecting a signal.

What maintenance or replacement will this HDMI multi-viewer need over time?

The unit has no user-serviceable parts; only the IR remote may eventually need a standard coin-cell battery replacement.

What resolution limit appears first when running all four inputs continuously at 4K?

The HDMI 1.4 interface caps each input at 4K 30Hz, so sustained quad-view operation cannot exceed 30 frames per second per source.
