- 1While watching, press RIGHT → Diagnostics.
- 2Read the “resolution” line: 3840x2160 is real 4K, 1920x1080 is Full HD, 1280x720 is HD.
Many channels branded “4K” or “UHD” are actually 1080p feeds — the app shows exactly what the provider sends. If the resolution says 4K but the picture looks wrong (stripes, blocks), send support a photo of the Diagnostics panel.
