I just acquired Sky Sports Ultra HD and the picture is very dull with terrible colour. The normal Sky Sports HD channel is great. If I change my brightness and colour settings for the ULTRA HD channel I have to change back for any other channel. Which is hugely irritating, especially as I like to flick around. The BT UltraHD channel is the same for contrast and colour as their HD channels. Is this a fixable teething glitch, or is this as good as it gets for my old telly? Because I will discontinue the service if it does not change. No drama, the  HD is fine anyway.

The Sky Sports UHD channels use HDR/HLG - and your tv needs to be able to cope with that to get correct brightess and colour.

HI @wokelly 

This is due to the Sky Sports UHD channels being broadcast in 10 bit HDR HLG and a number of older and less expensive TV's can't process it.

Some TV's have setting options that allow users to turn off HDR HLG or use 8 bits rather then 10 bits on their panel settings.

The main culprits seem to be Samsung TV's, and forum advice suggests checking that the gamma setting isn't too high, try 2.2

On my older LG Nano TV it improves if I turn off HDMI Ultra HD Deep Colour.
