It can be challenging to focus if your TV automatically changes brightness.

Not only does it irritate eyes, but the focus is also lost when suddenly the screen becomes dark, and after a few moments, it is light again.

Constant brightness changes make it difficult for eyes to adjust to the screen, making watching TV tedious.

The following might be one of the reasons why your Hisense tv keeps dimming:

  • Brightness Settings
  • Manually Changing Settings
  • Contrast Enhance
  • Eco Mode

1. Brightness Settings

This issue is usually found in new TVs as initially, they operate on factory settings until the user configures settings according to their requirement.

You can easily set the screen brightness by doing the following:

  • Go to the setting panel of the TV. You can either search it manually or directly press the ‘settings’ button on the remote.
  • After this, a drop-down menu will appear select display settings, and from here, you can adjust screen brightness.

2. Manually Changing Settings

Sometimes, you might need to change picture settings manually depending on your viewing content. You can also change these settings by going to the video section in ‘settings’.

You can change settings and view other options related to the video display.

3. Contrast Enhance

Contrast enhance or Dynamic enhance is a setting in the display panel that changes brightness according to the displayed scene.

When this setting is ‘ON’, as soon as the scene becomes dark, the brightness also dims down to make dark areas appear darker.

Similarly, as the scene changes to a bright scene, screen brightness also increases to accommodate that.

This might be turned ‘ON’ in the factory setting, so if you want to focus on the details of the picture, then you need to turn it ‘OFF’ in the display settings.

4. Eco Mode

Some models of Hisense TV have a new mode, i.e., the ‘Eco Mode’, which adjusts screen brightness according to the light in the surrounding environment.

As evident from the name ‘Eco’, the concept is to save power. When the Hisense Smart TV software notices that the surrounding environment has become dark so, to save power, the screen’s brightness is reduced.

Once the room is well lit up, the screen’s brightness automatically increases as well.

Depending on the model, you can switch off Eco Mode by the following steps:

  • Going to the ‘Settings’ option
  • Find the ‘Power’ option in the settings tab
  • Turn off the ‘Low power mode’, which turns off the Eco Mode, and fix the dimming issue.
