Why Is The ‘TV Mode Not Supported‘ Error Popping Up On My Samsung TV Screen? 

There are a few reasons for this error. One is a poor connection on the HDMI or VGA ports on your Samsung TV. The HDMI and VGA are used to connect your Personal Computer to the TV. The ‘TV Mode Not Supported’ will automatically pop up on your TV screen when this connection is faulty. Sometimes, your Samsung TV may not recognize HDMI input hence causing the errors to pop up on your screen.

 The mentioned error also comes in when your Samsung TV Resolution is not supported mainly because the image sent to it from your PC or DVD is extremely high or low that is not supported by the TV’s resolution.

Outdated TV software may also contribute to this error. Your TV could be too old and hence using outdated software.

How Do I Fix The ‘TV Mode Not Supported’ Error?

We have stated earlier that this error will constantly appear on your screen when the image sent to the TV from the DVD player or PC is either too high or too low resolution. We have some remedies for this problem. Here they are:

  1. Turn off your TV and the other device connected to it
  • Turn off the TV for about 10 seconds or more.
  • Switch on the TV first and wait for a few seconds before turning the other devices on. Confirm if this works.
  1. Connect a device that has an output resolution that can be supported by your Samsung TV

The device connected must output a resolution that can be supported by Samsung TV. If the device outputs a higher or lower resolution, you may change or upgrade. The following are resolutions applicable on a Samsung TV;

  • 1080 i/p
  • 480 i/p
  • 720 i/p
  • 2160 i/p
  1. Set the resolution of the device connected to your TV

Setting the resolution of the external device could work. This will control the output produced such that it is not too high or too low.

  1. Change the external device connected to your TV via the HDMI port.

Select or connect a device with the same/equal resolution as your TV. This could help it work better and curb the error.

  1. Check the software of your Samsung TV

Outdated software may lead to cause this error. It is necessary to confirm whether the software is up-to-date. You may choose to connect the TV to devices that match the TV’s software age and vice-versa

  1. Use HDMI cables that are about 6 feet long or slightly longer

HDMI cables longer than 8 feet may be faulty at times and therefore necessary to choose a cable that is slightly shorter than 8 feet but not shorter than 6 feet.

How Do I Reset The Resolution On My Samsung TV?

  1. Click the’ Home’ button
  2. Choose ‘source’ and specify whether it is ‘Play station’ or ‘Comcast’
