UGREEN HDMI to VGA Adapter Male to Female 1080p Black – CM611
The key distinction of this adapter is that it performs an active digital-to-analogue conversion. HDMI carries a digital signal; VGA, however, requires an analogue signal. The CM611 contains a built-in conversion chipset that handles this translation internally, which is why a passive cable or dongle without a chipset cannot perform this function. Additionally, for source devices that output insufficient power through the HDMI port — such as certain smart TV boxes, older Mac Minis, and Raspberry Pi units — a USB-C port on the adapter body accepts optional supplementary power from a USB-C cable (sold separately). As a result, the adapter operates reliably across a wider range of devices that might otherwise fail to display.
The adapter is built with a tinned copper wire core for consistent conductivity and housed in a durable ABS case with an environmentally rated jacket. Furthermore, the compact form factor and 15cm cable length make it portable enough to carry in a laptop bag or toolkit without adding bulk. Moreover, plug-and-play operation requires no driver installation on Windows, macOS, or Linux, so setup is immediate on any supported platform.
Important compatibility notes: This adapter is unidirectional — it therefore carries signals from HDMI source devices to VGA displays only. VGA-to-HDMI conversion is not supported. Additionally, VGA carries video only; audio does not pass through this adapter. As such, a separate audio cable is required for sound output.

Use Cases and Applications
Laptops and Ultrabooks to VGA Projectors
Conference rooms, training facilities, and classrooms frequently use older projectors with VGA inputs as their primary display connection. A presenter with a modern laptop — which outputs only HDMI — can therefore connect directly to the projector using the CM611 without any software configuration. The plug-and-play design means no driver installation is required before the presentation. Moreover, the 15cm pigtail avoids the leverage stress on the laptop’s HDMI port that a rigid male-to-female dongle would otherwise create.
Desktop PCs and Workstations with Legacy Monitors
Organisations running mixed hardware environments often retain functional VGA monitors alongside newer equipment. Consequently, a desktop or workstation with HDMI graphics output connects directly to a VGA monitor using the CM611, extending the useful life of the display without requiring a new monitor purchase. Additionally, the optional USB-C power port provides a fallback for graphics cards or integrated graphics that output low bus power through the HDMI port, thus broadening device compatibility.
Raspberry Pi, Single-Board Computers, and TV Boxes
Raspberry Pi and similar single-board computers, along with compact Android TV boxes, frequently encounter display compatibility issues when connected to VGA monitors because their HDMI ports output at reduced power levels. However, the CM611’s USB-C supplementary power input resolves this by drawing power from a separate source. As a result, the adapter’s conversion chipset operates reliably regardless of bus power availability. The 90813 is therefore a practical choice for educational, maker, and embedded computing environments where VGA displays remain in active use.
