LG C8 HLG settings question
Hi guys, someone uses the HLG format at his OLED? I use it regularly on my 77C8, as I am filming with my Panasonic GH5 in HLG. The results are fantastic, my vacation movies look quite like those reference HDR discs from Planet Earth etc.. Very impressive.
But the following oddity: In any HDR mode EXCEPT "standard", bright scenes, such as a beach in the sun, noticeably darkened within a few seconds. I can really watch, as soon as I switch from standerd to i.e. Cinema Home, it is initially bright as it should be... but about 10 seconds later, it only looks "dimm". This happens as I said in all HDR presets when I use HLG, except the standard setting. Set to “standard”, the picture remains bright as it should be, even in high-APL scenes. I have tested it with different firmwares, 4..and 5.. no difference.
The usual suspects, such as automatic brightness etc. are of course switched off.
Well, this is not that dramatic now, I can use "standard" and that's great. But I would just like to know why the other modes behave like that. Does anyone have experience with it? Or maybe can test with a high APL HLG (in a very bright scene)? Or does anyone else have an idea? Just out of interest, would be great to know, what´s going on there. Thank you in advance.
