Alyosha2001 I have purposefully never updated the TV, so it is still running Android TV 7.0. It does not have Quick Settings. However, it does have the regular Android TV Settings, and there is a Power Saving entry:

Settings - Power - Eco - Power Saving - [Off, Low, High]

The following captures have been made with brightness set to 5 and light sensor disabled; the distance to the TV is always the same:

Power Saving "Off" (the flicker here seems to be the 60 Hz panel refresh rate flicker):

Power Saving "Low" (20 KHz flicker):

Power Saving "High" (still 20 KHz):

    Very useful, so Power Savings got to go! Really need an oscilloscope

    Any tips on how to get the brightness below 5 without the flicker?

    I recently bought a TV, but I don't think the blue light from the TV will affect my child's eyes, so I'm thinking about installing a blue light blocking screen protector?Is this a better way to protect my child's eyes, because I don't want my child to be short-sighted.

      Most tv`s should have the ability to reduce the blue light in the color temperature settings

      Don't know about the flicker, though

        KM Shouldn't PWM go to 0 on the lowest amplitude? Maybe it's another type of flicker

        KM Do you think that if I set the brightness to 5 and then set any of the R-Gain, G-Gain or B-Gain lower could trigger the PWM? (Would it be like forcing the panel to lower brightness than supported by DC Dimming?)

        Also, could you tell me how to prevent the full black thingy (like when it turns off the illumination), as just watching a movie fading to black can trigger that.

        I'm really trying to find the usable settings for it

          Alyosha2001 No PWM or backlight flicker here when changing the Gains, but always keep in mind my model is 2 years older and I use an old Android version.

          To prevent the "black screen" flicker, I sideloaded the app "OnScreenClock 0.5.0k.apk" to permanently display the current time in a corner of the screen. It turned out, as I had hoped, that when some non-black pixels (the clock) are always displayed, the screen isn't recognized as fully black and the backlight won't go to flicker mode then.

            KM That's weird. Even if the brightness is set to 5? That means that it can have a brightness below 5 without the pwm if all sliders are draged to the left?

            Wait, you have a clock watermark when you're just watching TV?
