4K channels can look stunning, especially sport, but only if every part of the chain supports them.
Checklist
| Part | Requirement |
|---|---|
| TV | 4K resolution, HDMI 2.0 or newer input |
| Device | 4K output and HEVC decoding (Fire TV Stick 4K, Shield, Apple TV 4K, 4K Android boxes) |

Real 4K vs upscaled
Some "4K" channels are HD feeds scaled up. Real 4K keeps small details sharp: scoreboard text, crowd faces, grass texture. Upscaled HD looks smooth but soft.
When to choose HD instead
- Your connection drops below 25 Mbps in the evening.
- Several people stream at once.
- You watch on a phone or small TV.
Viking IPTV offers 4K and Full HD where available; Full HD is the dependable everyday choice. See internet speed for IPTV.
