What causes my Vizio TV to flicker?
The flickering of your Vizio TV can be attributed to several factors, including issues with the HDMI connection, problematic settings, or hardware malfunctions. A loose or damaged HDMI cable often interferes with the transmission of the signal, resulting in screen flickering. Additionally, if you’re using a non-compatible device or a faulty connection, it might lead to display issues.
Another possible cause is related to the refresh rate settings on your TV. If the refresh rate does not match the output from the device connected to your Vizio TV, it can create a flicker effect. It’s essential to ensure that your TV and the connected devices are set to compatible refresh rates to prevent flickering issues.
