Reasons for Screen Resolution Errors on ONN Devices

Table of Contents

Here are the reasons for screen error on an ONN device.

Automatic Resolution Setting Enabled – The ONN device may default to “Automatic” mode, which locks resolution changes. This prevents users from manually selecting their preferred resolution.

Power Source Issues – A loose or faulty power connection can cause unstable performance.
Faulty or Inconsistent Wall Outlet – If the outlet isn’t supplying steady power, the ONN device may struggle to maintain the chosen resolution.
Using TV USB Ports for Power – Many TV USB ports don’t provide sufficient power for ONN devices and USB might not work on TV. This can result in lagging, interruptions, or even device malfunction.

Loose or Damaged HDMI Connection – A poorly connected HDMI cable or problem with HDMI display port can cause resolution errors, blurry visuals, or intermittent signal loss.
Device or TV Compatibility Limitations – Some TVs or monitors may not support higher resolutions available on the ONN device.

How To Fix Screen Resolution Errors on ONN Devices

1. Change Screen Resolution on ONN

Here are the steps to change resolution on an ONN device.

Power on your ONN device.
Make sure it’s connected to your TV and running properly.

Navigate to the gear icon on the home screen to access system settings.
Go to “Display & Sound”.

This section controls your video and audio output settings. Select “Resolution”. Here you’ll see the current resolution setting—likely set to a lower default resolution.

Turn off “Automatic” option.

This setting may prevent manual changes. Disable it to unlock full control.
Choose your preferred resolution you prefer depending upon the avaiability.
Confirm and apply the changes.

Your screen may flicker briefly as the new resolution takes effect. Wait for some time and check. You might need to adjust the resolution few times and check what works for you.

2. Check The Power Source

Now, if after changing the resolution, you are having screen related issues on your ONN device, then check the power source.

Ensure the power cord is securely plugged into the TV and the wall outlet.

Test the outlet with another device to confirm it’s working.

If using a power strip or surge protector, try plugging the TV directly into the wall outlet.

3. Test Different Outlets

You can try plugging the power adapter into a different wall outlet to see if the current outlet is faulty.

You can also use a different power cable and adapter to rule out any issues with the original power adapter.

4. Avoid the USB Ports

The next thing you should ensure is that you are not using any USB port on your TV unless it is specifically designed to provide enough power for the ONN device.

Using a TV’s USB port for your ONN can be risky as it can cause crashes or other issues.

Most TV USB ports don’t provide the necessary power that the ONN needs to function properly. This can lead to interruptions, lagging, or even damage to your device.

5. Check The HDMI Connection

For a stable and clear connection on your ONN device, check the HDMI connection between the device and your TV or the monitor you are using.

Ensure the HDMI cable is firmly connected to both the ONN device and the TV or monitor’s HDMI port, as a loose connection can lead to issues like this.

Look over the HDMI cable for any visible signs of wear and tear, such as fraying, kinks, or bends. If you find any damage, consider replacing the cable with a new one.
