How to fix TCL Roku TV pictures too dark

If you’re using a TCL Roku TV and suddenly notice that the pictures appear too dark, you’re not alone. Some users have even reported that their device’s screen is so dim that it’s turned black, rendering any text or gray shades invisible. This issue can happen without any changes being made to your TV’s settings.

While the screen may appear fine in other scenarios, the problem becomes apparent when you switch on live TV or streaming apps. But what is causing this issue, and how can you fix it?

The likely culprit for your TCL Roku TV’s too-dark pictures is an incorrect picture mode or a low or zero brightness level. In addition, captions can also affect the screen’s brightness, with the screen lightening when captions are on and dimming when they’re off. Inaccurate local dimming and contrast settings may be the cause in such cases.

Other reasons that could contribute to your TV’s dark pictures include changes in the lighting level of your room, hardware issues affecting the screen’s brightness, and out-of-date software.

It’s also possible to experience this problem after updating your TCL Roku TV’s software.
