Have you been using your Samsung TV lately and noticed that it displayed a message that said “Mode Not Supported,” you’re not alone. Unfortunately, this message seems to be popping up more and more frequently on Samsung TVs, with affected users reporting that the TV won’t turn on or will randomly switch channels.
So what do you do if your Samsung TV is displaying this message? If you have a Samsung TV, there may be some workarounds for getting around this issue. This post will show you how to fix the problem of Samsung TV mode not supported suddenly.
What Does “Mode Not Supported” Mean?
This common error message appears when you attempt to connect HDMI devices to the Samsung TV. It means the TV cannot process the data sent to the television by the connected device.
There are several reasons why this might happen. First, if the device and TV are incompatible, the TV may not handle the data sent to its HDMI port. Second, if the device sends data at a resolution that is too low or too high, then the TV won’t display the data correctly.
To fix this problem, you’ll need to troubleshoot the issue. Try connecting another HDMI-connected device to the same TV and see if the problem persists. If it does, you’ll need to determine whether the device or TV is incompatible.
How to Fix Samsung TV “Mode Not Supported”?
If your Samsung TV is displaying the “Mode Not Supported” message, there are a few things you can do to try and fix it.
1. Restart Both the TV and the Device
If your Samsung TV is not displaying video or other content in the correct mode, you may need to restart it. Any external device plugged into the TV should also be unplugged and restarted before attempting to reboot the TV. This will fix most issues with the TV not displaying correctly.
To restart the TV:
- Make sure the TV is turned off completely by pressing the power button. If you press the power button again, the TV will turn on after 15 seconds.
- To restart the external device:
- Unplug the device from the TV. Press the power button once to turn off the device. Then, press the power button on the device to turn it back on.

4. Set an Output Resolution on the External Drive
If you’re using an external hard drive to store your photos, videos, and music and have a Samsung TV, it might not recognize the drive. You’ll need to set the output resolution on the external drive to fix this problem.
The TV and external device can both be set to the highest resolution. The following instructions will help you set the TV’s resolution on your PC:
- Locate the search bar on your PC

HDMI cables are typically about 3-25feets long. If your Samsung TV is connected to a Blu-ray player or other high-definition device using a longer HDMI cable, the signals from these devices may be too weak for the TV to recognize them correctly. A shorter HDMI cable may solve this problem.
6. Change the HDMI Device
Another way to resolve the problem of the TV “mode unsupported” message is to disconnect the device from the TV and reconnect another HDMI device on the TV. If the problem still occurs, you may need to replace the HDMI cable between the two devices.
7. Confirm That the Device Outputs a Supported Resolution
If you are trying to connect your Samsung TV to an external display and the resolution of the display is not matching, likely, your Samsung TV does not support the resolution of the external display.
Samsung only supports the following resolutions:
| Supported resolutions |
| 2160p or 3840×2160 or 4096×2160 |
| 1080p or 1920×1080 |
| 720p or 1280×720 |
| 480p or 640×480 |
The display is likely incompatible with your Samsung TV if the resolution is not listed.
