The problem of half the screen being darker is quite common among Samsung TV users. As the name suggests, this problem makes one side of the TV screen look dim while the other side stays bright. Various things, like issues with the backlight, problems with the T-Con board, or a glitch in the software, can lead to this.

This problem can seriously affect your TV-watching experience. The dark part of the screen can make it hard to see what's going on, which can be annoying. It might also strain your eyes and make you tired, especially if you're trying to focus on the dim part of the screen.

Basic Troubleshooting

If your Samsung TV is facing the issue of half the screen being darker, you can try these simple troubleshooting steps:

1.Restart the TV

Turn off the TV, disconnect it from the power source, wait a few minutes, then plug it back in and turn it on again.

2.Check cable connections

Make sure all cables are firmly connected to the TV and devices they are linked to.

3.Ensure all settings are default

Verify that all picture settings are at their default values. If you've made any adjustments to the settings, consider resetting them to their default values.

Optimizing Your Samsung TV's Display

Here are some adjustments you can make in your TV settings to potentially fix the issue of half the screen being darker:

Backlight

Increase the backlight setting to brighten the darkened side of the screen. Be cautious about setting it at a reasonable price, as it may lead to problems like light bleeding and reduced contrast.

Contrast

Adjust the contrast setting to enhance overall picture quality and make the dim side of the screen more visible.

Brightness

Raise the brightness setting to help illuminate the darker portion of the screen. However, be mindful not to increase it excessively, as it could result in washed-out colors and reduced contrast.

Local Dimming

If your TV has a local dimming feature, activate it to improve contrast and diminish the darkness on one side of the screen.

These adjustments might differ based on your TV model and the extent of the issue. Try these settings individually and observe their impact on the screen before making further changes. If the problem persists, seeking assistance from a service technician may be necessary.
