degen Yes, my XG80 has Android 7. There are features I have to turn off or I get tightening, too (basically when something flickers). Those features are:
- Clearness (it's black frame insertion)
- Adv. contrast enhancer
Those features adjust the backlight and use PWM.
I would recommend to set any inputs to Game or Graphics mode. I have set the brightness to 37 (auto disabled) which has the least measurable flicker. It could be different from the new model.
Something else I found: when devices send a black screen (in-between loading for example), the TV software decides to reduce the backlight, applying PWM. It seems this cannot be turned off. To counter it, I set the Black level option to 51 instead of 50. A similar thing is Home - Settings - TV - Channel setup - Info banner. It works for all inputs (not just TV) and needs to stay turned on. It displays an info banner when you switch TV channels or when connected devices switch resolution. If you turned this off, the screen would go black for a short time, the backlight would turn down and you'd look at PWM.
The LED below the Sony label also flickers a lot, so I suggest to turn it off in the settings.
My Picture settings:
- Graphics mode or Game mode
- Brightness 37 (Light sensor off)
- Black level 51
- HDR mode off
I set Contrast to max but that's not really an eye strain setting, just making the picture a little better.
The settings have to be adjusted for each HDMI input.
Make sure to have all remaining features turned off at first or leave them at default settings to see if this helps.
When going into Android apps, I noticed Android has its own display settings which are not accessible while you're watching TV or using HDMI. Make sure to switch to Game or Graphics mode for Android apps, too and also adjust the other settings there, too.
I hope this helps.
