I am aware that this model is not HDR but, a few months ago, an update made it HDR compatible.

I have downloaded HDR content from here

http://demo-uhd3d.com/

and played it from a USB stick. When HDR content is detected the TV switches to a locked picture setting to display the HDR content to the best of its ability.

Also in the update, the description of the Enhanced Features for HDMI inputs added the wording "Including HDR". I inferred from this that if I connected a device capable of sending HDR to the TV that it would switch to display it as it does for content from a USB stick.

I recently bought an Xbox One S which, when probing my TV (with Enhanced Features enabled), tells me that it is not HDR capable and the option to send HDR is greyed out. My question is: what was the point of making the TV HDR compatible if it doesn't send this information to devices connected to it by HDMI? Or should it send that information and the fact that it doesn't is yet another software glitch??

Has anyone any thoughts on this?

Many thanks.
