GUIDE · 4K and HD quality
4K and HD picture quality in the UK
Picture quality depends on more than the service. This guide explains what 4K and HD require and how to check what you are actually watching.
1What the service offers
Channels are delivered in 4K UHD wherever the broadcaster provides it. Not every channel or title is broadcast in 4K, so check the channel list or the title's details for the ones you care about.
2Your device and TV
Both the streaming device and the TV must support 4K, and the HDMI port and cable should support it too. Check the device's display settings to confirm the output resolution.
3Your connection
4K needs a steadier, stronger connection than HD. A wired connection helps most; if the picture keeps pausing, lower the quality in the player.
4Checking real 4K
Look at the player's stream information, if available, or the TV's info display while a 4K channel plays. If it shows a lower resolution, check each link in the chain in turn.
| Situation | What to check | Tip |
|---|---|---|
| TV far from the router | Wi-Fi signal strength in the device's network settings | Use an Ethernet cable, a powerline adapter or a mesh access point. |
| Several people streaming at once | How many devices are using the connection at the same time | Pause large downloads and cloud backups while watching live TV. |
| 4K or high-quality channels | Whether your plan, device and TV all support that quality | Drop to a lower quality if the picture keeps pausing. |
| Problems only at certain times | Whether drops match busy evening hours | Run a speed test from your provider's tool at good and bad times and compare. |
| Streaming stick on Wi-Fi | Which Wi-Fi band the stick is using | Prefer the faster band near the router; consider a wired adapter for the stick. |
Checklist
- Confirm the content is offered in 4K
- Check device and TV support 4K

Frequently asked questions
Is 4K available?
Channels are delivered in 4K UHD wherever the broadcaster provides it.
Why am I not getting 4K?
Check that the content, your device, your TV, the HDMI cable and your connection all support 4K. If one does not, the picture falls back to HD.
Is HD good enough?
For many screens and connections, HD or Full HD looks sharp and plays more steadily. Choose 4K when your whole setup supports it.
Is there a contract or automatic renewal?
No. You pay once for the term you choose and nothing renews on its own.
Can I get my money back?
Yes — every term includes a 30-day money-back guarantee.
