Why Does My Samsung TV Keep Dimming?
Samsung TV auto-dimming is a built-in feature for regulating light and ensuring your viewing is enjoyable. The Ambient Light Detection feature works with the settings to save on the power usage of your smart TV. When the surrounding is brighter, your Samsung TV screen adjusts to ensure you see the content. If the lights are off, the screen dims to ensure the setting suits you.

Instead, the contrast ratio leads to dynamic contrast. The contrast ratio co-relates the darkest color(dark) your screen can display to the brightest color(white) that your screen can illuminate.
If your Samsung smart TV uses dynamic contrast, there will be a greater contrast ratio. So, the light colors will seem brighter, and the dark colors will look darker than before. This effect causes dimming, making the screen appear darker than usual.

However, if the contrast doesn’t satisfy your viewing experience, you can turn it off and use the configurations done.

Samsung TV auto-dimming may also be attributed to the LED backlights of your smart TV. If you’ve configured the contrast ratio, but your TV is still dim, there is a likelihood that the TV has its hitches.

HDR to SDR Display-HDR display may be ideal for improving contrast between dark and light TV colors. However, switching the display to SDR is preferable, which supports standard and video content. In addition, SDR provides a brighter viewing experience and can be ideal for eliminating the dimming effect.
Power Saving Mode: Your Samsung TV has built-in power-saving functionality that cuts the cost of energy. However, you’re likely you lose out on illumination and picture quality. You can configure your power-saving settings and brighten your screen display by avoiding picture mode and setting it to common.
