Why Does My TV Say Not Supported?

If a device is connected to the television and the message “Not Supported” pops up on the television, here is what may be happening.

Why Does My TV Say Not Supported

If your television has a message saying “Not Supported,” don’t hurry back to the store to return your device. Most of the time, the fix is something simple that you can do in a manner of minutes.

The reasons your television might not support the device might be because the resolution is not supported, there is an issue with cable connections, there is a firmware update, or a bug has appeared on the television.

By following the next steps, you will be able to pinpoint the reason the device is having trouble connecting to your television set. If the problem is not resolved on your first run-through, I recommend going back and applying the solutions at least once more.

1. Resolution Not Supported

The most likely reason that a device is not connecting to your television is that the resolution that is being cast by the device is not supported by the television. The resolution refers to the number of pixels being displayed on a screen.

If a device’s resolution is not accepted does not always mean that the resolution is higher than that of the television, it might mean that the resolution that is now being utilized to present the images from the device is higher than that of the device.

Sometimes the resolution on both the television and the device is the same, but the way in which the television is connected to the resolution is not optimal. The fix for this problem is quite simple to follow.

Fix 1 – Cast A Supported Resolution

The first fix that you might want to follow is to change the resolution directly on your television to match that of the device you are trying to connect to the TV. To do this, you must first know at what resolution the device works.

Most likely, this information will be found somewhere in the box in which the device came. If not, it is a good idea to look for the device on any web browser.

Since the resolution will be one of the most important aspects of any device that is meant to be connected to a television, it will be quite simple to learn the resolution that best suits the device.

Once you know what type of resolution the device is running on, you must then change the resolution on the TV to that of the device.

To do this, you must head to your television settings, and under the display, you shall be able to change the resolution that your device requires.

Fix 2 – Set Resolution on Your Output Device to Automatically Detect the Best Resolution

If you have manually changed the resolution on the television and there still seems to be a problem with the connection between the device and the television, then you should look for the option to detect the best resolution for any given device automatically.

This will make sure that whichever device you might connect to the television will first be examined by the TV to determine what the best resolution settings will be for any given device.

To turn on this setting, you must head onto settings on your television, select the display settings, and look for the “Automatically Detect Best Resolution” option.

Most likely, this option will be easy to find since most of the televisions already have this option integrated within their factory settings.

If, for any reason, the option is not already turned on, then turning it on may save you precious time after utilizing other devices on the TV.

At times the option to detect the resolution of a device will not correctly work or detect the optimal resolution for the device, and that is why trying to change the resolution from a manual setting to an automatic one to see if the device is now showing on the TV.

2. Issue With Cable Connections

After you have already tested fixing the problem by changing the settings for the resolution on the television, the next thing you will have to do is check the cables used to connect the external device to your television.

Even if you have bought brand new cables to connect the new device, it does not mean that the cables will be automatically connected the way that they are required to.

Fix 1 – Check Then Reconnect Cables from the TV and The External Device

To solve this problem, you should first disconnect every single cable that has been used to connect to the television. After you have disconnected all of the cables, reconnect them all, making sure that every single cable is placed correctly.

Most of the cables used for televisions are meant to be simply plugged in, but if for any reason a cable needs to be screwed in, make sure that the cable is completely screwed into its entrance.

If, after you have connected every cable correctly, there are still issues with the connection, you should disconnect the cables once again and check the cables in their entirety to see if there are no tears or any noticeable folds along the cable.

If there are any sort of bumps or cuts alongside the cable, this could mean that the cable is not sending the correct electrical signals needed to make both the device and the television communicate with one another.

If it is possible, utilize all the cables that are needed to connect the device to the television onto another device to test if the cables work correctly. If this is the case, then changing the cables for new cables should fix the problem you are facing.

It is also important to check that the cables are not getting folded at any part of the cable because if the cables are being folded, it is possible that information is not getting passed completely between the TV and the device.

3. HDMI Issue

Continuing with the trend of malfunctioning cables, HDMI cables have become the standard type of cables that most companies use in order to connect their devices to the television.

Because of this new universal standard, we are beginning to see that devices do not require the same amount of cables in order to operate.

But since there are fewer cables to connect them, this means that if the cable is not working correctly, the whole system will cease to function the way it is meant to.

HDMI cables have the advantage of being much more rugged and thick than other cables and therefore have a duration that is much longer than past cables used in older generations of devices.

Thanks to the necessity of only one cable to connect the TV means that there are not as many factors to consider when connecting the device.

But this also means that a faulty cable will cause the television to be unable to connect to the device, regardless of any other factor.

Fix 1 – Reconnect HDMI Cable

First, what you will want to do if your device uses an HDMI cable to connect to the television will be to disconnect the cable from both the television and the device.

Once the cable has been disconnected, you can go ahead and reconnect the cable to both the device and the television.

While you are reconnecting the cable, one thing you might want to keep in mind is to let the cable run freely and straight into the device and the television.

If there is anything that might interfere with the cable, say if the cable was to be folded in order to reach either the device or the TV, this might cause interference that will not allow the TV to communicate with the device.

If this is the case, I might recommend obtaining a larger HDMI cable or a cable that is meant for rougher circumstances if the obstacle that is forcing the cable to fold onto itself can not be removed.

If you have made sure that the cable is straight and without any obstacles, check to see if the device is now detected by the television.

Fix 2 – Replace HDMI Cable

If you have reconnected the HDMI cable onto both ends and there still are problems with connectivity, replacing the HDMI cable (view on Amazon) might be the next step to follow.

Since most HDMI cables are much thicker than other cables, it might be difficult to see if there are folds made at any part of the cable or if cuts are present on the cable.

Before you go out to buy a cable, you might want to test that same cable with any other device that too uses HDMI to connect to the television.

Since HDMI has been moving into turning to the universal cable that is used by most modern devices, it will not be very difficult to find another device that requires the cable as well.

If, after connecting the cable to another device, the problem persists, replacing the cable will now be a requirement for the purpose of making sure the device has every opportunity needed to work at its fullest capacity.

In order to make sure that the cable will last for as long as possible, be sure to buy a cable whose length is the required one for the television to connect to the device, as well as make sure that the thickness of the cable is the best option for your current situation.

4. TV Firmware Out of Date

As previously stated, most new televisions have integrated their software to work continuously via the internet. This is due to the fact that there is a great need for streaming services to be available with as little trouble as possible.

It is also an integrated part of televisions so as to enhance the images displayed on the screen, the applications found within the television, or the connection of external devices.

All of the updates to firmware are made available for the purpose of making utilizing a TV faster, safer, and much richer.

That is why firmware that is out of date may cause a problem when it comes to detecting and connecting new devices. If the newest update is available for the TV, it is possible that various devices will not be detected correctly.

Fix 1 – Update Firmware

To fix this problem, you must update the firmware on the television. To do this, you must head to settings on your television menu. After reaching the settings menu, search for support.

This option may be found straight from the settings menu, and if not, it might be found in the about section found on settings. To reach the about section, you may need to select “My TV” on settings.

Once you open up the needed menu, search for “Check for Firmware Update” and click on it.

This will most likely bring up a loading page to show you how big of an update will be necessary to download and how long said download will take on your current internet connection.

The updates might take up to 10 minutes to complete. An update might not directly mention the problem that you are facing, but this does not mean that updating will not fix your problem.

Often times an update will add much more features than the ones mentioned since the update will indirectly help the function of various settings.

Once the download is completed and installed, try to connect the device once more to see if the television detects the device.

5. There’s A Bug

If you have followed all of the steps shown beforehand, there might be a bug that is causing the television to be unable to connect to the device.

A bug is an error in the code of a device or site that makes one or several options offered by the product to be unreachable.

A bug tends to be one of the scariest problems to think about when trying to operate a device, but this fear comes from not knowing if the bug is actually occurring.

Since it tends to be difficult to know if there even is a bug in the code, it might be fear-inducing to try and fix the problem. But the ways to fix this problem are not as complicated as one might think them to be.

Updates, often times referred to as patches, are meant to keep the television working at its fullest potential; that is why it is extremely important to make sure that your television is updated to the latest firmware available.

Fix 1 – Restart TV

The first and most simple solution to this problem is to restart the television. Restarting a television is not like restarting other devices such as cellphones and computers.

In order to restart a television, you must first turn off the television using the controller. If a controller is not available, then turning off the television directly from a button found on the television itself is also a viable option.

Once the television is turned off, you must wait at least 30 seconds before you turn it on the television again. The action of turning off and on a TV will make all of the previously used settings and applications refresh to their predetermined settings.

Turning off the television using a controller does not turn off the device like it would turn off a laptop. Turning off a television will place the television on standby rather than forcing the television to no longer actively pass electricity.

Fix 2 – Cold Restart TV

The second thing that you may try with the intention of getting rid of any bug that may be causing a problem with connectivity will be to cold restart your TV. This is quite different from restarting the TV.

When restarting a television, the TV does not completely shut off; it merely shuts off the screen and closes all applications. It is a means to place the television on standby.

With a cold restart, the power to the television is cut off, therefore forcing the television to turn off and reboot, just like restarting a laptop.

To do this, you must first have your television turned on and unplug the television directly from the power source.

After unplugging the television from the outlet, you must wait at least 30 seconds to give the television enough time to reboot completely. After waiting 30 seconds and plugging in the television, check to see if the device is now detected by the television.

Fix 3 – Factory Reset TV

If none of the previous steps have worked and the connectivity problem remains in your TV, you will want to factory reset the television.

Compared to restarting or cold restarting, a television factory reset will delete all of the information that has been downloaded onto the television. Only the programs and settings that come from the factory will be available after the factory reset.

If you choose to go this way, it is possible to download all of the apps that were previously available on the TV. To factory reset the television, first, you need to disconnect any device that had externally been added to the TV.

Factory restarting is a little different for every television. On a Samsung television, it is done by opening the settings and heading toward the general. After selecting general, the option to reset will be available. Resetting your pin will be necessary.

If you have not customized your pin on the TV, the default pin is (0000). On the other hand, in order to factory reset a Fire TV, you must press and hold the Back button together with the right side of the navigation circle on the remote.

After pressing and holding them for at least 10 seconds, a menu will pop up asking if you wish to continue or cancel the reset. Once the factory reset is done, check to see if the device is being identified by the TV.

Fix 4 – Contact Manufacturer

If you have tried all of the fixes shown in the article at least twice, then there might be an error with the television itself. If you believe you have tried and followed every fix possible, the step you would like to act upon is to contact the manufacturer of the television.

Most modern televisions have a guarantee of at least a year, meaning that any problem you might find while using the TV will be repaired without any charge. When calling the manufacturer, you must have the serial number of the television available.

The serial number and all of the needed information of the TV might be found in the about section of the settings menu. Most likely, you will be required to send the television back directly to the manufacturer through the mail.

Adding a new device to your television is now easier than ever. Thanks to the firmware installed into almost every modern television, most devices are detected automatically by the television.

Even when some of these factors may be causing the error on television, there are many ways to fix it. Try every solution presented in this article, and the television will be able to work the way it was meant to work.
