As long as you have enough bandwidth (ie your line is fast enough), we'd expect our customers to be able to stream Ultra High Definition (
UDH) 4K video, even at peak time.
===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.
