The UGREEN CM571 (90478) is a 2-port HDMI KVM switch that allows two computers to share one HDMI monitor, keyboard, mouse and USB accessories. With HDMI 2.0 connectivity, four USB 2.0 ports and supplier-listed 4K@60Hz output, it offers a convenient way to manage a dual-computer workstation.
Whether switching between a work PC and a personal computer or managing two systems at a technical desk, the CM571 reduces repeated cable changes. Explore the UGREEN 90478 HDMI KVM Switch price in Bangladesh at IT Source.
Running two computers at one desk should not require two sets of peripherals. The UGREEN CM571 (90478) brings both systems into a shared workstation, allowing one HDMI monitor, keyboard and mouse to be used with either computer.
Each computer connects to the switch through an HDMI video input and a USB-B host connection. The active computer sends its video to the connected display and receives control of the shared USB peripherals.
The device includes four USB 2.0 Type-A ports for compatible accessories such as keyboards, mice, USB flash drives and printers. Computer selection is available through the physical button or a wired desktop controller.
Unlike a video splitter, the CM571 shows only the selected computer. It does not display both computer screens simultaneously.
The UGREEN CM571 features an HDMI 2.0 interface, with suppliers listing a maximum output of 3840 × 2160 at 60Hz. This makes it relevant for users working with high-resolution monitors, detailed spreadsheets, design applications and everyday multimedia.
Lower display resolutions, including Full HD, are also supported. Actual video output depends on the graphics hardware, monitor capabilities and HDMI cables used.
Some regional listings for SKU 90478 conflict on the maximum 4K refresh rate. Buyers requiring guaranteed 4K@60Hz operation should confirm the rating printed on their product packaging or manufacturer documentation before purchase.
The CM571 provides two HDMI inputs and two USB-B host connections, allowing two compatible computers to remain connected to the same KVM unit.
This setup is useful when a desktop PC handles demanding applications while another computer is reserved for office work, testing or separate user accounts. Both computers can remain connected without occupying additional space for a second keyboard and monitor.
Only the selected computer appears on the HDMI display and controls the connected USB peripherals. The switch is intended for one active display source at a time.
Four USB 2.0 Type-A ports allow compatible keyboards, mice, flash drives, printers and other USB accessories to be shared between the two computers.
USB 2.0 offers a theoretical signaling rate of up to 480Mbps, suitable for common office peripherals and everyday file transfers. It is not designed to provide the higher transfer rates of USB 3.0 or USB 3.2 storage connections.
When the selected computer changes, the connected USB peripherals are redirected to that computer. This reduces the need to unplug accessories and reconnect them manually.
The UGREEN CM571 offers two straightforward switching methods: a button on the main KVM unit and a wired desktop controller. Both methods let users change the active computer without disconnecting the monitor or peripherals.
The wired controller is especially useful when the KVM unit is placed behind a monitor or underneath a desk. It allows cables to remain organized while the switching control stays close to the user.
Keyboard hotkey switching is not established for this SKU, so the physical button and wired controller are the supported switching methods described here.
The HDMI connection carries compatible digital video and audio from the selected computer to the connected monitor or HDMI audio equipment. This allows users to switch the active computer without separately moving the HDMI audio connection.
Supplier documentation lists support for Windows, macOS and Linux computers with suitable HDMI and USB interfaces. Standard KVM functions are designed for plug-and-play operation without dedicated KVM software.
USB accessories may still require their own operating-system drivers, and HDMI audio playback depends on the capabilities of the connected equipment.
Measuring approximately 98 × 58 × 24mm, the UGREEN CM571 has a compact ABS and PS enclosure suitable for small office desks and home workstations.
Its dedicated HDMI inputs, HDMI output and USB host connections help keep cables from both computers connected in one place. A separate Mini-USB connection is also listed among the device inputs.
For installation, connect each computer through HDMI and USB-B, attach the shared monitor and USB peripherals, and select the active computer using the physical button or wired controller. Confirm any supplementary power requirements against the supplied unit.
The UGREEN CM571 is suitable for office professionals using separate work and personal computers, home users who want to reduce desk clutter, and IT technicians who need to switch between two systems.
It is particularly useful when one monitor and a common set of USB accessories are sufficient for both computers. Users who need simultaneous dual-computer viewing or two independent monitors should choose a different switching solution.
