Default Active HDR

Forgive me if there's another thread already. I see these LG class uk6200 TVs are big time on sale now. They have Active HDR, so should these be able to do HDR 10 and what's with Active HDR as I haven't seen much mention of it?

Default LG :: Active HDR (UK6200)

LG :: Active HDR (UK6200)
  • it's creating dynamic metadata for HDR10 & SDR ('scene by scene')
  • or, creating scene by scene metadata when there already is none

It’s basically this:

Compared to most other models from other brands, LG prioritizes tone mapping ‘down’ to preserve as much detail in brighter areas as opposed to clipping them. This makes APL go lower which makes overall brightness for some films low, however, IMO, if you watch it in a dark room that is not a problem. Sony (up until now anyway) and other brands clip at some point to preserve a higher overall brightness level.

It's really not a world apart from the Dynamic Contrast they've had in their TVs for ages then?

Not sure if that statement is true but they’re definitely not the same. Tone mapping tries to save as much detail as possible in dark and bright areas, and dynamic tone mapping does it better since it’s done depending on the objects in the image of a specific scene (for HDR content). Dynamic contrast can be done on top of dynamic tone mapping, and in both SDR and HDR cases it usually crushes detail in dark or bright areas. Most home theater enthusiasts leave it off since we know what it does, it might look more ‘pleasing’ to the eye but it’s usually at the expense of information in the image.

What’s confusing is that in some 2017 LG models the ‘switch’ to activate dynamic tone mapping was within the Dynamic Contrast setting since LG added dynamic tone mapping to those models after they were released and the UI had been finalized, so there was not a dedicated setting for it so they added under Dynamic Contrast. 2018 LG models also have the same kind of dynamic tone mapping but they do actually have a dedicated section in the UI for the settings for dynamic tone mapping. That was definitely confusing for some people but LG clarified it in one of their white papers for the settings for the proper 2017 models.

Active HDR is designed to take the static metadata HDR formats such as HDR10 and tries to makes them perform more like dynamic metadata HDR formats like Dolbyvision and HDR10+ (if that ever really hits the market.)

For a good explanation of static vs. dynamic metadata check out:

Spoiler Alert: Dynamic Metadata is better.
