Hisense U7K HDR issue on Sky Q content

[Luke00]

I recently bought this new tv. Most content looks great, however on recorded/downloaded HDR content the tv dims significantly. Other content such as on Disney+ , Netflix etc. look fine. What is causing this issue?  I've heard it may be to do with the HLG format but not too sure...

hi @Luke00 

It is very likely that your TV does not have a bright enough peak brightness to work with the type of HDR that SKY uses which as you have read is called HLG.

This type of HDR needs a screen with a peak brightnes of at least 600 nits (aka cd/m2) - unfortunately you may not be able to find this detail in any specifications.

Streaming apps such Netflix, Disney+ & Prime do not use thiis type of HDR which do not cause any dimming

It may be possible that playing with the Settings you may be able to get a watchable picture

What does the picture look like watching UHD contenton the inbuilt iPlayer ?
