Use your Android tablet as an HDMI monitor with UVC capture video and audio.
Turn your Android tablet into a portable HDMI monitor. HDMI Monitor lets you view an HDMI signal fullscreen through a USB UVC HDMI capture adapter. It's plug and play: connect your capture card and your HDMI source opens fullscreen on your tablet screen. Compatible capture adapters can also play HDMI audio through your tablet. Use it for camera feeds, game consoles, laptops, mini PCs, streaming setups, field work, diagnostics, and any workflow where a lightweight external display is useful. Key features: - Fullscreen HDMI signal viewing - Starts fullscreen automatically when you plug in your capture adapter - Resumes automatically when an unplugged adapter is reconnected - HDMI audio playback through compatible capture adapters - USB UVC HDMI capture adapter support - Signal presets for quality, smoothness, and compatibility - Pinch to zoom and pan the live preview - Aspect controls for fit, fill, and stretch - Rotation and flip controls for flexible setups - Retro CRT Filter (Pro) with scanlines, richer colors, and subtle shading - Warm fullscreen exit for faster re-entry - Safe Eject before unplugging your capture device - Debug diagnostics for troubleshooting UVC connections HDMI Monitor is built for Android tablets and UVC capture cards. It does not turn a USB-C port into direct HDMI input. A compatible UVC HDMI capture adapter is required. Compatibility notes: your tablet must support USB host/OTG mode and use a data-capable cable or adapter. Capture adapters, video formats, USB audio formats, available power, and Android USB implementations vary by device. HDCP-protected video may not display. If a detected adapter cannot provide a usable UVC video mode, the app explains the issue before you start monitoring. How it works: 1. Plug your HDMI source into a UVC HDMI capture adapter. 2. For audio, select HDMI as the sound output on your source device. 3. Open HDMI Monitor. 4. Connect the capture adapter to your Android tablet. The signal opens fullscreen with sound. 5. If the adapter was already connected, tap Scan Device, then Start. Android identifies capture adapter audio as microphone input, so microphone permission is required for HDMI audio. Use HDMI Monitor when you need a simple, focused external display without carrying a dedicated monitor.
