We need to talk about HDR

[Flatpanels]

Our review of Sony A8H (A8) is online. It's also sold as the A85, A87 and A89. The 2020 OLED model comes with new features like Android 9, Dolby Atmos, Apple AirPlay 2, HomeKit, and improved BFI.

Thank you for the review.

I'm a bit confused by the Brightness with BFI chart. It seems to suggest that HDR drops by only 103 nits in HDR (BFI setting 1), which is far less than I was fearing.

I heard that the HZ1000 drops by 300 nits (in HDR) in low BFI mode, so 103 nits doesn't sound that bad.

Would you say BFI at setting 1 or 2 is usable in HDR mode?

Is this still an issue? Im very worried about the Dolby Vision part of this TV as we in the family watch a lot of netflix etc. I actually had an LG CX but returned it due to too much magenta tinting. Not paying premium cash for a lottery panel where clouds look like a candyfloss. Back to topic - The LG however was bright and fine in HDR and DV. I know its TV-Led and not Low latency Player- Led as the Sony uses, but its just "brighter"

When watching Ozark, Haunting of Hill house and more the picture dimmed alot. Now as I understand the Sony carries over SDR to HDR hence tonemapping is locked and cannot be altered resulting in also dimming in that way.

My question is - Do anyone think Sony will fix this looking at a 2 year old thread and its still a problem?
Secondly is this only an issue when watching DV to to the LLTV way Sony uses.
Say watching an 4K movie from a player will it also dimm the picture?

When seeing the LG CX VS SONY A8H shootout there was a lot of test picture and videos, and that made the sony the winner. In that youtube segment I couldnt see any dimming!!!

It drives me crazy

Hi Henrik. I believe what you are referring to is the overall darker Dolby Vision presentation on Sony TVs? You can circumvent this issue by using the built-in apps for Netflix etc. rather than an external HDMI streaming player.

The issue discussed in the other article is actually a different one. It's a dimming algorithm in the OLED panel that will make the picture darker with time when it mistakingly detects a picture as static. It is there to protect against burn-in. The dimming algorithm has since been tweaked and our impressions is that it few are bothered by the effect after the tweak.
