描述

This HDMI to VGA active converter is designed to solve the compatibility problem between new-generation HDMI source devices and traditional VGA display equipment. It is widely used in office desktops, conference room projections, industrial control terminals, security monitoring systems and teaching demonstrations, converting digital signals from laptops, desktops, set-top boxes, security DVRs, industrial PCs and Blu-ray players into analog VGA signals for output to legacy CRT monitors, LCD displays, projectors and video walls.

Unlike passive conversion cables, this product adopts an active conversion chip solution with a built-in high-performance digital-to-analog conversion circuit, delivering more stable signal output and broader device compatibility. It avoids common problems of passive solutions such as black screen, flickering and unsupported resolution, and maintains clear image quality even over long-distance transmission. It supports a maximum resolution of 1920×1080@60Hz full HD, and is backward compatible with common resolutions such as 720P and 480P, adapting to most mainstream VGA display devices.

Equipped with a 3.5mm stereo audio output interface, it can be directly connected to speakers, headphones or power amplifiers, solving the problem that VGA interface cannot transmit audio, and realizing synchronized audio and video output. It complies with HDMI 1.4 specification and is compatible with HDCP 1.2/1.4 copyright protection protocols, working properly with set-top boxes, Blu-ray players and other HDCP-protected content source devices.

The converter supports HDMI bus power supply. For high-load or long-distance transmission scenarios, additional 5V power can be connected through the side Micro USB interface to ensure stable conversion without frame drop. It is plug-and-play without any driver installation, and compatible with mainstream operating systems including Windows, macOS, Linux and Android, as well as all devices with standard HDMI output.

The compact housing design is made of wear-resistant ABS or metal material, with a small footprint, suitable for desktop placement, cabinet wiring and equipment integration. It is widely used in legacy display upgrade, conference room projection transformation, industrial control terminal display and security monitoring wall mounting. For bulk OEM orders, we support custom housing color, logo printing, cable length and packaging style.
