Telemetry and diagnostics

The Metrics tab, /?tab=metrics, exposes information about what the TV is doing and what hardware it contains — most of which is absent from its own settings menu.

This is useful both for monitoring and for troubleshooting. It shows whether a high-temperature condition is accompanied by CPU load, what Wi-Fi signal the TV actually has, what HDMI mode a connected device negotiated, and what software is currently running.

• SoC temperature and current draw, CPU and per-core load, GPU clock, memory and swap, Wi-Fi RSSI and network throughput.
• eMMC flash wear with JEDEC health translation, and free space on the app partition.
• HDMI link state per port, refresh rate, colour depth, pixel clock, and HDMI 2.1 diagnostics where supported (link rate, chroma format, HDCP version, cable error counter, ALLM, VRR, QMS and colorimetry).
• Dolby Vision / HDR / SDR detection, picture mode, OLED light level, the raw HDMI signal (3840x2160 @ 120Hz), audio output routing, and the running app with friendly input names (Apple TV (HDMI2)).
• Magic Remote battery and model; webOS and firmware version, SoC architecture, OLED cell ID and TCON firmware where the platform exposes them.
• On demand: what is resident in memory, and which processes are using the processor right now.

Metrics including processor, memory, swap and current draw.
