Encountering the “Mode Not Supported” error on your Samsung TV can be frustrating, especially when it prevents you from enjoying your cable TV. This article aims to provide a comprehensive guide to resolving this error, allowing you to fix the issue quickly and get back to watching your favorite shows. By understanding the possible causes and following the step-by-step troubleshooting process, you can ensure compatibility between your input device and Samsung TV.

Understanding the “Mode Not Supported” Error:

The “Mode Not Supported” error occurs when your input device’s display mode is incompatible with your Samsung TV’s supported resolutions. Even if your TV supports 4K resolutions, it may not support all possible aspect ratios or resolutions. This error can also arise due to issues with the HDMI cable or outdated software on your TV.

How to fix Mode not Supported Samsung Tv Error

Encountering the “Mode Not Supported” error on your Samsung TV can be resolved by following the troubleshooting steps

#1. Ensure Casting at a Supported Resolution:

To resolve the error, you must verify that your input device outputs a resolution supported by your Samsung TV. The TV supports resolutions such as 480i, 480p, 720p, 1080i, 1080p, and 2160p. Access the settings of your input device and ensure it is outputting at one of these resolutions.

#2. Power Cycle Your TV and Source Device: 

Sometimes, a simple restart of your TV or source device can fix the “Mode Not Supported” error. Power cycling involves turning off both devices, unplugging them from the power socket, waiting for a brief period, and then plugging them back in. Turning on the TV first, followed by the input device, can help reset the output resolution.

#3. Check for Software Updates: 

Outdated software on your Samsung TV can cause compatibility issues. Checking for and installing software updates can often resolve such errors. To check for updates, navigate to the Settings menu, select Support, and choose Software Update. If your TV is within the guaranteed update period, check for updates periodically.

#4. Use a High-Quality HDMI Cable: 

Sometimes, the “Mode Not Supported” error may be due to a faulty HDMI cable. A high-quality, short-length HDMI cable can ensure proper data transmission and potentially resolve the error. Belkin Ultra HDMI 2.1 is a recommended option that supports the latest HDMI standards.

#5. Try a Different Source Device: 

To determine whether the issue lies with your TV or the input device, connect your Samsung TV to another input device and switch the input accordingly. If the error persists with other devices, it may indicate a configuration issue with the input device or incompatibility with your Samsung TV.

#6. Reset Your Samsung TV: 

If previous steps fail to resolve the error, resetting your Samsung TV to factory defaults might help. Access the Settings menu, navigate to Reset, enter the PIN (default is 0000), and select OK to initiate the Reset. Alternatively, you can find the factory reset option under Support > Self-Diagnosis. Refer to your TV manual for specific instructions.

#7. Contact Support: 

If all troubleshooting steps have been exhausted and the error persists, it is recommended to contact Samsung support. They can provide further assistance and, if necessary, arrange for a technician to inspect your TV for hardware-related issues.



Encountering the “Mode Not Supported” error on your Samsung TV can be resolved by following the troubleshooting steps outlined in this article. You can effectively address the error by ensuring compatibility between your input device and TV resolution, power cycling, checking for software updates, using a high-quality HDMI cable, and exploring alternative source devices. If these steps do not resolve the issue, contacting Samsung support is recommended for further assistance.
