Having a TV set in Dynamic mode pretty much guarantees that the backlights will be working close to- or at- maximum. There's only so much brightness they can produce, and when they're maxed out then they can go no brighter. Like fitting a small engine to a car, the lighting elements that are left have to work much harder. That's not nice to read, but it's what happens. That's because the LEDs that light the screen cost money, and so the manufacturers fit the fewest they can get away with. Most 4K UHD TVs with HDR under about £800 have limited brightness output. Here's a bit of information you probably won't be happy to read, but it's essential knowledge. Switch off until your picture settings are done. Motion Lighting: Does the same as ESM (above) but triggered by movement. Once again, switch this off until your picture settings are done. If some portion of the screen needs to be bright, but in doing that it takes the energy consumption over a certain threshold limit, then the whole picture will get darker until the bright item is out of shot. This will appear as if the limit is based on the screen average brightness level. Energy Saving Mode: This one will put an artificial limit on how bright the picture can be. (This is also governed/overridden by the Backlight control setting in Expert Settings.) Disable this until all the rest of your picture control settings are complete. Minimum Backlight: works in conjunction with ALS to set a lower limit for how dark the screen can get. Turn ALS to Low, then make your picture brightness and contrast adjustments. Where you have the TV set to Dynamic, or have adjusted one of the other picture mode settings to make the picture dazzlingly bright, then the Ambient Light Sensor won't have much additional brightness left to make the picture brighter in daylight viewing conditions. Ambient Light Detection: A sensor reads how light or dark the room is and adjusts the screen brightness accordingly. You could also try turning this off to check the effect. Depending on the TV model, this could either try to dim portions of the screen that don't need to be bright such as shadow areas, or try to dim the whole screen when the scene is quite dark. Where the TV is already outputting at maximum light power, and there's no more energy available to make the bright parts of the picture even brighter, then the TV will turn to the darker portions of the screen and make them go dimmer in order to make a digger difference between light and dark. The one I would switch off is Contrast Enhancer. Settings > Picture > Expert Settings: too many options to list, but the specific ones you should look in to are Local Dimming and Contrast Enhancer. ![]() For ordinary viewing, Standard is a better starting point. In dynamic mode, any screen dimming will be exagerated. Settings > Picture > Picture Mode: Options for Dynamic, Standard, Natural, Movie. In no specific order, here are some of the main controls: How much it reacts, and how, is controlled by some of the settings you've already found such as ECO settings, but also by some other settings too. ![]() Your TV is reacting to the picture content.
