Key Features & Benefits

Simultaneous HDMI and VGA Output: Both ports activate together without switching or reconfiguration, allowing a laptop screen to mirror to two displays at once. This is particularly useful in presentation environments where the room projector uses VGA while a confidence monitor uses HDMI — a common scenario in older conference rooms and lecture theatres.
4K@30Hz HDMI with HDMI 1.4b and 3D Support: The HDMI port outputs at up to 3840 × 2160 @ 30Hz via HDMI version 1.4b, covering 4K televisions, 4K monitors, and all Full HD displays. Additionally, HDMI 1.4b carries 3D video content to compatible displays without any further configuration.
Up to 1920×1200@60Hz VGA Output: The VGA port supports resolutions from 1024×768 up to 1920×1200, covering the full range of legacy analogue monitors, projectors, and classroom displays. The 60Hz refresh rate ensures smooth, flicker-free output across all supported resolutions.
24K Gold-Plated Connectors: Both the HDMI and VGA output jacks use 24K gold plating to minimise contact resistance and resist oxidation. Furthermore, the scratch-resistant ABS plastic shell protects the adapter body during transit and daily handling.
Plug and Play — No Driver Required: The MM123 operates without software installation on Windows, macOS, iPadOS, Chrome OS, and Android (where DP Alt Mode is supported). Audio passes through the HDMI connection simultaneously, removing the need for a separate audio cable to the display.

UGREEN MM123 USB-C to HDMI VGA Adapter – 4K@30Hz Dual Output (White)

The UGREEN MM123 is a compact USB-C converter that provides simultaneous HDMI and VGA video outputs from a single USB-C port, making it one of the few adapters that bridges modern digital displays and legacy analogue projectors in a single device. It delivers up to 4K@30Hz over HDMI and up to 1920×1200@60Hz over VGA, with both ports active at the same time. Consequently, it suits professionals presenting in conference rooms with older VGA projectors, educators connecting to mixed display environments, and home users running dual-monitor setups from a USB-C laptop.

Use Cases & Applications

Conference Room and Classroom Presentations

The MM123 is specifically suited to environments where a laptop must connect to two displays simultaneously — typically a VGA projector at the front of the room and an HDMI confidence monitor or secondary display for the presenter. Both outputs activate automatically when the adapter is connected. However, dual-output mode locks to mirror mode at 1920×1080@60Hz, which is the native resolution of most projectors and conference monitors. This resolution renders presentation slides, documents, and spreadsheets clearly on both screens without any resolution compromise.

Connecting to Legacy Analogue Displays

Many older projectors, monitor banks, and in-room AV systems use VGA exclusively. The MM123 provides a direct VGA connection from a USB-C laptop without requiring a separate HDMI-to-VGA converter in the signal chain. Additionally, VGA supports up to 1920×1200@60Hz when used as the sole output — a resolution that exceeds 1080p and suits widescreen monitors with a 16:10 aspect ratio.

Single-Display 4K Output via HDMI

When only the HDMI port is in use, the MM123 outputs at the full 4K@30Hz ceiling. This suits home users connecting a MacBook or USB-C Windows laptop to a 4K television for video streaming, photo review, or desktop extension. Audio transmits through the HDMI connection simultaneously, covering stereo and surround-capable displays.

Important Notes

DP Alt Mode required. The MM123 does not function with USB-C ports that carry power or data only. Confirm device compatibility before purchase.
Dual output is Mirror Mode only. When both HDMI and VGA are connected simultaneously, the adapter outputs at 1920×1080@60Hz in mirror mode. Extended (dual-screen desktop) mode is only available when using a single output at a time.
VGA carries no audio. When connecting to a VGA display, audio must be routed separately through the device’s built-in speakers or a separate audio output.
Charging is not supported. The MM123 carries video signals only. A separate power connection is required during use.
HDMI and VGA cables are not included. The adapter provides the output ports; cables to the display must be supplied separately.
