And it’s a feature found on the majority of smart TVs nowadays.

Black Detail modifies the television’s average brightness.

In contrast, Backlight Control automatically calibrates the contrast ratio of the television. Thus, the brightness has increased. And dark is much darker.

A malfunctioning lighting could be the leading cause of a flickering screen. However, you cannot rule out a power issue either.

If they are also flashing, then a power fluctuation is occurring. Therefore, you should momentarily turn off your power supply.

However, if only the television is flickering, it could be a faulty outlet.

Additionally, you should inspect the TV’s power cord. Ensure that it is securely attached to the TV and the electrical outlet. And if it is broken, seek a replacement.

Therefore, if you are using one, inspect it for flaws.

And attempt to clean it by eliminating dust or buildup of debris. You may accomplish this with a cleaning brush.

Additionally, ensure that you are using a more recent version of HDMI cable.

Vizio suggests using versions 2.0 and 2.1.

It is also conceivable that the flickering screen is caused by a faulty port.

Vizio televisions have at least four HDMI ports. Attempt to connect your external device to another of these ports. Additionally, ensure that you have the correct input setting on your television.

In rare circumstances, the screen flickering is not caused by the television. Alternatively, the wires and ports.

Instead, an external device is responsible.

Therefore, a simple approach to determine this is to disconnect all of your TV’s external devices.

Then, execute a power cycle on the television.

Did the flashing cease?

If this is the case, the problem lies with the connected device.

Therefore, regardless of whether the gadget is a gaming console or a media player…

Check any settings that could cause image problems. Additionally, confirm that it is undamaged and flawless.

Additionally, you may quickly reset it by disconnecting it from the wall socket.

Therefore, you must keep the firmware of your Vizio television up to current.

In addition to new features, these upgrades often offer bug fixes.

No longer is there a menu option on the Vizio TV to manually install updates.
