Eight-port HDMI KVM with dual mirrored outputs
This 1U rack-mount switch lets one keyboard, mouse and two mirrored monitors control up to eight computers running Windows, Mac, Chrome or Linux. It delivers true 4K at 30 Hz resolution (3840 x 2160) with HDMI 1.4 and HDCP 1.4 compliance, and also handles 1080p, 720p and 480p signals. A built-in 3.5 mm audio extractor and USB 2.0 hub share peripherals such as printers or scanners across all connected PCs. The package includes eight dedicated KVM cables for immediate deployment.
Plug-and-play setup with six switching methods
No driver installation is required; simply connect the supplied cables and power the unit. Users can change ports via front-panel buttons, an IR remote, the wired desktop controller, keyboard hotkeys, mouse gestures or RS-232 serial commands (232 baud). Auto-scan cycles through ports at adjustable intervals from 8 to 999 seconds. A common issue is expecting extended desktop mode — the switch only duplicates the same image on both monitors — so verify that mirrored output suits the workflow before purchase.
Consistent zero-latency switching under sustained
The hardware provides seamless, blank-screen-free transitions whether switching manually or running long auto-scan sessions, keeping keyboard, mouse, video and USB peripheral paths stable over time. HDMI 1.4 bandwidth limits the dual outputs to 30 Hz at 4K, so extended high-refresh workloads stay at 1080p or lower. The 1U metal chassis dissipates heat passively, and the RS-232 interface enables automated control scripts for unattended, round-the-clock operation in server rooms or broadcast racks.

Questions about this item
How do I confirm the KVM is switching sources with zero latency after connecting eight computers and two monitors?
When you change ports using the desktop controller, hotkeys, mouse wheel, front button, IR remote or RS232 command both monitors should update instantly with no blank screen; the duplicate 3840x2160@30Hz image appears on each display without delay.
Which cables and peripherals are included in the box and what must I supply myself?
The package contains eight HDMI KVM cables for the computer links; you provide the two HDMI monitors, one USB keyboard, one USB mouse, any USB 2.0 peripherals for the shared hub and an optional RS232 control cable.
Should I choose a different version if I need extended desktop across the two monitors instead of mirrored output?
This unit only supports duplicate display on both outputs, so if extended desktop is required you would need a different KVM model that explicitly lists extended-mode support.
