HDMI Resolution Scaler is an all-in-one HDMI signal processing device integrated with audio extraction and audio embedding functions, solving common display incompatibility and audio separation troubles for home entertainment, live streaming and office scenes. Supporting up to 4K@60Hz high-definition signal input and adjustable output resolutions of 720P, 1080P and 4K, this converter perfectly matches old monitors, traditional televisions and modern display screens that cannot identify ultra-high-definition HDMI signals directly.

Different from ordinary single-function HDMI audio splitters, our device adopts bidirectional audio processing architecture. On the one hand, it extracts pure audio signals from HDMI video sources through independent coaxial SPDIF digital port and 3.5mm analog audio jack, enabling you to connect to home theater amplifiers, sound bars, headsets and desktop speakers separately without relying on TV built-in speakers. On the other hand, it realizes audio embedding function: you can input external sound sources via coaxial or 3.5mm audio port, mix the extra audio into HDMI output signals, which is ideal for game live broadcast, video recording and multi-source audio mixing creation.

No complicated remote control required. The front panel is equipped with intuitive MENU, plus/minus adjustment and ESC shortcut keys. You can quickly switch output resolution, adjust audio volume, modify digital audio decoding mode and save customized settings in seconds. All operations are completed on the device itself, bringing straightforward operation experience.

Dual independent input and output areas are clearly divided on the rear panel. The input terminal supports HDMI signal input, external coaxial audio input, 3.5mm analog audio input and DC 5V power supply port; the output terminal provides HDMI video-audio mixed output, coaxial digital audio output and 3.5mm stereo audio output. The DC 5V low-power power supply design ensures continuous stable signal transmission without frame drop, screen flicker or audio delay during long-time use.

This HDMI converter is widely compatible with mainstream HDMI source devices, including PS5, Xbox series game consoles, laptop & desktop computers, TV set-top boxes, Blu-ray players, media players and camera capture cards. It works seamlessly with most HD displays, monitors, projectors and audio amplifiers on the market, breaking the limitation of mismatched resolution and single audio output interface of traditional audio splitters.
