==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
***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:
**Use a wired connection rather than WiFI
**Try speed test sites to check your connection, you'll be wanting to see about 20Mb/s or more

***http://fast.com (Netflix's speed test)

*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:
