What ifle format to display on an HDR TV

[Olivier.A]

After editing an image I want to display it on an HDR capable TV. What is the file format and also the colourspace / bits depth to use in this case to get he most of the TV ?

I don't know yet is image will be on a usb stick plugged in the TV or downloaded from the inter via the wifi connexion.

Thanks !

You'll need to find out what the TV's able to display if you're using a USB stick, but JPEG will work.  I'm not sure what you mean by "downloaded from the inter via the wifi connexion" - do you mean streaming from a server,  casting, something else? 

No matter how you do it you'll need to adjust the TV to prevent it changing the image too much, e.g. by oversharpening.

Sorry, I've been vague here. On my TV, you have a mode and app to grab image from local server on my network. Just like UB stick, but remotely. I can imagine new service providing the same online... As it's a connected TV.

JPEg would work, of course, but without taking the benefit of the HDR and extended dynamic range of the TV. Basically what is "jpeg" of HDR images

OK, something like Plex?  Unfortunately, I don't think there's a simple answer to your question.  My photography group has recently started using an HD TV (but not HDR) as a laptop monitor but it's being criticised for being too inaccurate.  It's not surprising that the TV settings have a big effect, but so does the image display software.  Chances are that both your server and TV software are also going to have an effect.  

There's also the problem of defining HDR - it's not an agreed standard so your TV might only support 8 bit colour depth even though it's being marketed as HDR.

Possibly JPEG-HDR, but I think you'll need to experiment with your own setup to see how things behave in the real world
