Resolution is one part of picture quality. HD and native 4K contain different pixel detail, but the final result also depends on compression, decoding, output and display. A television reporting a 4K input does not prove that the programme itself was supplied in native 4K.
Why it matters
Higher-detail streams can demand more from the network and decoder. Upscaling changes output without recreating absent source detail. Stable lower-resolution playback may suit a session better than an interrupted higher-demand source.
Work through the steps
- Distinguish programme source information from HDMI output settings.
- Compare equivalent source choices only where actually available.
- Review network and decoding before blaming the panel.
