When we take photographs of a real world scene bright regions may be overexposed, while the dark ones may be underexposed, so we can’t capture all details using a single exposure. Or, at least, as much of the full effect as your TV is capable of.Today most digital images and imaging devices use 8 bits per channel thus limiting the dynamic range of the device to two orders of magnitude (actually 256 levels), while human eye can adapt to lighting conditions varying by ten orders of magnitude. You can always switch it back to HDR on the occasions you're watching movies in a dark room and want the full effect. If you can't get a bright enough HDR picture in your sunlit living room, go to the menu of your streaming box, head to its display settings, and turn HDR off. There's no shame in this- some would even argue that HDR is really meant for dark-room viewing anyway. Go back to SDR: Finally, if none of the above works well enough for you, there's one last-ditch option: watch your shows in SDR during the day.The colors won't be as accurate, but it might counter the ambient light and make the picture look brighter. In other cases, you may even want to go so far as choosing the Standard picture mode. ![]() ![]() "That preset is specifically optimized for dark-room viewing," says Heron, which is why some TVs have a "Cinema Home" mode that's brighter than the regular Cinema mode. Change your picture preset: You've probably read TV guides that say you should put your TV in Movie or Cinema mode for the most accurate picture, and that's true-but this may look too dim during the daytime.Changing it to 2.0 or lower may help the picture appear brighter. Tweak your gamma: If your TV has a Gamma setting, it's likely set at 2.2 by default.Certain presets may dim the entire image to keep black levels as deep as possible, which is not necessary in a well-lit room. Adjust local dimming: Again, this setting is probably already set to its ideal level, but just in case, open your picture settings and play with the Local Dimming option (if your TV has one). ![]() (Sony TVs are the exception, where the Backlight setting is labeled "Brightness.") Some TVs may not let you adjust the backlight any higher in HDR mode, but others will. Raising the brightness might brighten the picture a bit, but it'll also crush shadow detail. Note that you want to crank the Backlight setting, not the Brightness setting, which should almost always stay at its default value.
