About the UGREEN CM293 (70439)

The UGREEN CM293 is designed to make a four-computer workspace easier to manage. Instead of connecting a separate keyboard, mouse and monitor to each PC, users can keep their equipment connected to one central KVM switch.

The device features four HDMI video inputs and four USB-B host connections for the computers. One HDMI output connects to the shared monitor, while two USB 2.0 and two USB 1.1 peripheral ports accommodate compatible accessories.

When a computer is selected, its video appears on the monitor and the connected USB devices are assigned to that system. The other computers remain connected, ready to be selected when required.

The CM293 is particularly useful for IT maintenance, software testing, computer administration and workstations where several PCs need occasional access through the same peripherals.

Design & Performance

Four-Computer Management Through One Display

The UGREEN CM293 brings four HDMI-equipped computers into one shared workstation. Each system uses a dedicated HDMI input and USB-B host connection, allowing its video and USB controls to be selected together.

This setup helps IT technicians inspect different computers without reconnecting a monitor or keyboard each time. Office users can also manage separate work systems while keeping their desk free from duplicate peripherals.

The KVM operates with one selected computer at a time. It does not combine four computer screens into a simultaneous multiview display.

4K@60Hz HDMI 2.0 Video Performance

The CM293 supports HDMI 2.0 video output up to 3840 × 2160 at 60Hz. This provides detailed visuals for compatible UHD monitors, making it suitable for desktop applications, large spreadsheets, software interfaces and other high-resolution tasks.

The product-specific technical documentation also lists HDCP 2.2 and HDCP 1.4 compatibility. Protected video playback remains dependent on the connected source, display and content requirements.

For 4K@60Hz transmission, the documentation specifies suitable 28AWG HDMI cables up to 5 meters on the input and output sides. Longer 4K cable installations may require operation at 30Hz instead.

Four Shared USB Ports for Everyday Accessories

The UGREEN CM293 provides two USB 2.0 Type-A ports and two USB 1.1 Type-A ports. The USB 1.1 connections are intended for compatible keyboards and mice, while the USB 2.0 ports can be used with supported flash drives, printers and other peripherals.

USB 2.0 supports a theoretical signaling rate of 480Mbps, making it practical for routine peripheral connections and basic file access. Users requiring high-speed USB 3.0 storage performance should consider a KVM model with a newer USB interface.

Shared peripherals follow the active computer, helping users avoid repeatedly unplugging USB devices during work.

Physical Button and Keyboard Hotkey Switching

The CM293 supports switching through the device's physical control button and compatible keyboard hotkeys. Users can change the active computer while leaving the monitor and shared peripherals connected.

Physical switching is convenient when the KVM is within reach, while hotkey control can make frequent computer changes easier from the keyboard.

The product documentation also refers to computer detection and switching functionality. For supported keyboard shortcuts and operating behavior, users should follow the instructions supplied with their specific unit.

HDMI Audio and Compatible Operating Systems

Alongside video, the CM293 can transmit compatible digital audio through its HDMI connection. The product-specific technical document lists DTS, DSD and Dolby AC3 audio formats, including supported multichannel configurations.

This allows the selected computer's HDMI audio signal to reach a compatible monitor or HDMI audio device without requiring a separate analogue audio switch.

The KVM is listed for Windows, macOS and Linux computers equipped with suitable HDMI and USB connections. Standard KVM functionality is designed for driver-free operation, although individual USB accessories may require their own drivers.

Compact Desktop Design and Dedicated Power Connection

Measuring approximately 144 × 80 × 26mm, the UGREEN CM293 has a compact design that accommodates four computer connections without requiring a large desktop installation area.

Its PC and ABS housing provides an enclosure for everyday workstation use. A dedicated DC 5V power connection is available to support the switch's operation.

For installation, connect each computer through HDMI and USB-B, attach the shared monitor and peripherals, and supply power through the specified connection. Once connected, the operator can select the required computer using the button or supported keyboard controls.

Who It's For

The UGREEN CM293 is suitable for IT support professionals, computer repair technicians, system administrators and office users who need access to four computers without maintaining four complete desktop setups.

It is also useful for software testing, hardware troubleshooting and equipment management. Users who require four independent monitors or simultaneous viewing of multiple computers should consider a different display solution.
