Are you tired of seeing the frustrating message “Resolution not supported” on your TV screen? You’re not alone. Many people have encountered this issue, and it can be really annoying, especially when you’re trying to enjoy your favorite show or movie. But don’t worry, we’re here to help you diagnose the problem and find a solution.
What Does “Resolution Not Supported” Mean?
When your TV displays the “Resolution not supported” error message, it means that the TV is unable to display the video signal being sent to it. This can happen due to a mismatch between the resolution of the video signal and the TV’s capabilities.
In simpler terms, resolution refers to the number of pixels (tiny dots) that make up the image on your TV screen. The more pixels, the sharper and clearer the image will be. Common resolutions include 720p, 1080p, 4K, and 8K.
Why Does My TV Keep Saying Resolution Not Supported?
Now that we’ve covered the basics of resolution, let’s dive into the possible reasons why your TV might be displaying the “Resolution not supported” error message.
1. Incompatible Connection
The most common reason for this error message is an incompatible connection between the device sending the video signal and the TV. Here are a few scenarios where this might happen:
- HDMI version mismatch: If your device is sending a 4K signal, but your TV only supports up to 1080p, you’ll see the error message. Make sure you’re using the correct HDMI version (1.4, 2.0, or 2.1) that supports the resolution of your device.

What Is An Unsupported Resolution?
An unsupported resolution refers to a display resolution that is not compatible with the capabilities of your TV. This can occur when you try to connect a device, such as a gaming console or computer, that outputs a resolution that is not supported by your TV. When this happens, your TV may not be able to display the image correctly, or it may display an error message indicating that the resolution is not supported.
In some cases, an unsupported resolution can also refer to a resolution that is higher than what your TV is capable of displaying. For example, if your TV only supports resolutions up to 1080p, but you try to connect a device that outputs a 4K resolution, the TV may not be able to display the image correctly.
Why Does My TV Keep Complaining About The Resolution?
Your TV is designed to operate within certain technical specifications, and when you try to display an unsupported resolution, it can cause issues with the image quality or prevent the image from being displayed at all. When your TV detects an unsupported resolution, it may display an error message or warning to alert you to the issue. This is a safety feature to prevent damage to your TV or other devices connected to it.
In some cases, your TV may also be configured to automatically adjust the resolution to the highest supported setting, which can cause issues if the device connected to it is not capable of outputting that resolution. This can result in a poor image quality or no image at all.
How Do I Fix An Unsupported Resolution Issue?
To fix an unsupported resolution issue, you need to adjust the resolution of the device connected to your TV to a setting that is compatible with your TV’s capabilities.
