4K and HDR Setup Guide: Get the Picture You Paid For

Most 4K HDR TVs in the world are showing 1080p SDR content. The panel is ready; the chain is not. Fix the chain once and every stream improves.

The Chain

Source → cable → port → TV setting → content. A failure anywhere drops everything downstream.

Checklist

1. HDMI cable: must be "High Speed" or "Ultra High Speed" — old cables from 2015 cannot carry 4K HDR.
2. Correct port: some TVs limit HDR to specific HDMI ports (often labelled "HDMI 2.1" or "ARC").
3. HDMI mode: in TV input settings, set the port to "Enhanced format" / "Full bandwidth" — the default is often "Standard".
4. Picture mode: select a mode with HDR in the name when HDR content plays; "Game/PC" modes often bypass processing.
5. Streamer settings: the streaming device itself needs 4K output enabled (auto is often off).

Verify With Known Content

Play any 4K/HDR title and check your device's display info screen — it reports the active signal. If it says 1080p, work the chain again.

Then Fix the Source Quality

Hardware ready → pin the player to its highest quality. Browse HDR-friendly titles in the movies catalogue and confirm the picture mode switches when they start.
