NETFLIX Subtitles changes brightness on my 55X850D HDR

just got 55X850D. it's an android TV. netflix app is pre-installed.

 

upgraded my netflix subscription to Premium for HDR viewing. was watching "Marcopolo" from in TV apps, when i noticed dark scenes turned 'brighter' every single time there's English subtitles shown on screen. i turned off the subtitles and the dark scenes remained dark as it should.

 

is this known SONY bug?
is this known Netflix bug?
is there any solution to this yet?

thanks for the help in advance.

I had this problem too. It was only a problem for me in dark scenes, but many deamatic scenes are dark.

 

I have an XBR55x850D with latest software. It has HDR but NOT LOCAL DIMMING.

 

I believe that the TV is attempting make the subtitles brighter (white) in most cases by increasing the backlight (brightness).

This would probably work if only the area under the subtitles was brighter (local dimming), but the entire baclight seems to be increased in brightness. The dark colour get washed out.

 

I think this has been resolved in the NETFLIX app in the latest release. That's likely because the App controls the CC.

 

This is also a problem for other sources such as AppleTV and HDMI cable wher ehte app has no control.

 

Also, the latest software does not control CC on the antenna (TV) input. All CC are large and white on black. This worked before the last update.

 

My workaround is to:

1. minimize the size of the CC.

2. make the colour grey or yellow so that the TV doesn't try to go too bright.

 

Bur Sony SHOULD find a better solution for this expensive TV..

Re: NETFLIX Subtitles changes brightness on my 55X850D HDR

This is usually caused by the Advanced Contrast Enhancer (ACE) option in picture settings. Action menu>Picture adjustments>Advanced settings>Brightness. Set to Off. Note: Turning off ACE can affect black levels, combined w/Black Adjust using ACE can enhance black levels in dark scenes. So it's a trade-off - accept the brightness changes, or give up some level of control over black levels. If this is primarily an issue w/subtitles you can change picture settings depending on whether you are viewing content w/subtitles or not.

 

Important: You need to make this Picture settings change while on the HDMI input or Android video app you are using. Picture settings are maintained per external input (HDMI1, HDMI2, etc.) and also by app types for the Android apps on the TV, not globally.

 

Go to Action menu>Picture adjustments>Advanced settings>Brightness and set Adv. Contrast Enhancer to Off. You'll need to do that for each HDMI input and its assigned picture settings. E.g., if you use Cinema Pro on HDMI1 for your DVR and Cinema Home for your BD on HDMI2, you'll need to turn off Adv. Contrast Enhancer in both places.

I gave it a try. It makes a change but not much. The trade-off is a problem for me. If the backlight remained the same (whatever it is at the time) the blacks wouldn't get washed out. Perhaps the CC wouldn't be a bright. My workaround of small grey setters is more effective.

Yeah, I don't use ACE so it was turned off anyway for me.

In my previous testing this was working very well with dealing with the subtitles issue, but I haven't watched any HDR with subtitles recently, so I will have to check that out and see how it goes.

Glad you found a solution that helps you out. These things are kind of annoying, aren't they.

I experienced the same on my XBR65930D- very annoying but can be managed. I never use TV apps and prefer an external- faster streamer such as Roku Ultra- but the solution should work as well. From your computer (not the TV) log in into nexflix and change your subtitle preferences. Use yellow instead of white for the font collor- and make the font as small as you can confortably read. Leave the caption box semi translucid vs black. This will help. Additional changes such as turning on the TV light sensor (if available) and keeping the backligh to half its power will help as well.
