Streaming UHD 4K Video
As long as you have enough bandwidth, we'd expect our customers to be able to stream Ultra High Definition (UDH) 4K video, even at peak time.
Our aim is not to be the bottleneck, that means that the various interconnects we have between our DSL providers (eg BT, TalkTalk etc) and the many interconnects to various parts of the internet and content providers are not run at, or anywhere near, full capacity.
This means, that when our customers need to download at the full speed of their line that we would expect that to be possible even at the busiest time of the day or week.
Congestion == Low quality streaming
What to do if you have problems
- Check your TV hardware:
- Can your TV actually play UDH 4K content?
- eg, try playing UDH from a different streaming service such as Netflix, Youtube, Vimeo, iTunes, Amazon etc
- If you can play UHD 4K then there is probably not a problem with your TV hardware
- If you can't then check the
- HDMI cable (some cheaper cables may not be so great)
- HDMI input (not all HDMI inputs on a 4K TV will accept UDH 4K video)
- Use a wired ethernet connection instead of WiFi
- Try a different player - eg if you use a device such as an 4K Apple TV, try your Smart TVs built in Apps.
- Check your internet connection:
- Check our CQM graphs on the control pages
Your graph should look nice a clean - no red packet loss, not blue or green latency spikes. Whilst streaming you'll see the download shown. For example:
