The UGREEN CM154 (50280) is a 4-Port VGA USB KVM Switch designed to control four computers using one VGA monitor, keyboard and mouse. Supporting Full HD 1920 × 1080 resolution at 60Hz, three shared USB 2.0 ports and simple computer selection, it offers an efficient way to organize a multi-computer workstation.
Whether you maintain several office computers, troubleshoot desktop systems or manage an IT testing desk, the UGREEN 50280 reduces repeated cable changes. Explore the UGREEN CM154 VGA KVM Switch price in Bangladesh at IT Source.
Managing multiple desktop computers can become inconvenient when every system requires its own keyboard, mouse and monitor. The UGREEN CM154 provides a practical alternative by connecting four VGA-equipped computers to one shared set of peripherals.
Each computer connects through a VGA video input and a USB 2.0 Type-B host port. The selected computer sends its video signal to the shared VGA monitor and receives control of the connected USB keyboard, mouse and other compatible accessories.
With three USB 2.0 Type-A ports, the CM154 also provides peripheral sharing for supported USB storage devices and printers. Its USB-powered design eliminates the need for a separate dedicated power adapter during normal operation.
The CM154 displays one selected computer at a time. It is not a VGA splitter or multiview device, and it does not display all four computer screens simultaneously.
The UGREEN CM154 features four VGA computer inputs and four USB 2.0 Type-B host connections, allowing up to four compatible computers to remain connected to the same KVM switch.
This setup is useful for technicians who frequently configure, test or repair different PCs. Rather than moving the monitor cable and input devices between computers, users can select the required system while keeping the workstation connected.
The shared VGA monitor displays the selected computer, while the keyboard, mouse and USB accessories are assigned to that system. Each computer must have its VGA and corresponding USB host connections correctly paired.
The UGREEN 50280 supports video resolutions up to 1920 × 1080 at 60Hz through its VGA interface. This provides a suitable display format for office applications, operating-system setup, technical diagnostics and everyday desktop tasks.
It also supports lower video resolutions, including 720p and 480p, when used with compatible equipment. DDC support helps the connected computer communicate with the display regarding supported video modes.
Because VGA is an analogue video interface, image quality depends on the computer's VGA output, monitor compatibility and cable quality. The CM154 does not provide native HDMI or DisplayPort connectivity.
The CM154 includes three USB 2.0 Type-A ports for connecting compatible peripherals such as keyboards, mice, USB flash drives and printers. These devices can be used with the computer currently selected through the KVM switch.
USB 2.0 provides a theoretical signaling speed of up to 480Mbps, making it appropriate for common office peripherals and basic file transfers. It does not offer USB 3.0 or USB 3.2 transfer speeds.
When switching between computers, connected USB devices are redirected to the active system. Users should safely eject USB storage before switching to reduce the risk of interrupted file operations.
The UGREEN CM154 provides a physical button for selecting the active computer. This straightforward control method allows users to move between connected PCs without repeatedly disconnecting VGA or USB cables.
Button-based switching is especially practical for computer repair counters, testing benches and office workstations where an operator needs to access different systems throughout the day.
Some supplier descriptions also mention an optional wired desktop controller, but its availability is not consistently documented for SKU 50280. The physical button is the established switching method for this model.
The UGREEN CM154 uses its USB Type-B host connections to receive operating power from connected computers. This simplifies installation because a separate external power adapter is not normally required.
Its plug-and-play design allows standard KVM operation without installing dedicated switching software. The device is listed as compatible with Windows, macOS and Linux computers that have suitable VGA and USB interfaces.
For reliable operation, connect each computer's VGA output and USB host connection to the matching numbered inputs on the KVM. Individual peripherals may still require their normal operating-system drivers.
Measuring approximately 150 × 67 × 25mm, the UGREEN CM154 has a compact desktop design that fits into workstations where available space is limited.
Its dedicated VGA and USB connections help organize the cables from four computers around a single control point. This is particularly helpful in computer laboratories, IT maintenance areas and equipment testing environments.
Product-specific supplier documentation lists VGA transmission distances of up to 25 meters when suitable 26AWG VGA cabling is used. Actual performance depends on cable construction, signal quality and the required display resolution.
The UGREEN CM154 is suitable for IT technicians, system administrators, computer repair professionals and office users who need to operate several VGA-equipped computers from one workstation.
It is especially useful for hardware testing, operating-system installation and maintenance of computers with legacy VGA connections. Users with HDMI-only monitors or computers should check the requirements for suitable active video conversion equipment before purchasing.
