Have a hard time getting your Samsung television to recognize HDMI inputs and don’t know what to do next? In that case, you may want to read this article. Down below is all the information that you must know about the failure of HDMI input recognition on Samsung TVs.

The Device Is Unpowered

In layman’s terms, for Samsung televisions to recognize devices connected to HDMI inputs, such devices need to be powered. That means if the devices don’t receive power, your TV cannot recognize them until you change their power status. Naturally, a wide range of articles that cover the topic of Samsung TV not recognizing HDMI input add unpowered devices in the list of suspects.

Unstable Power Source 

So you have connected each of your devices to a power source but your television remains unable to recognize them? Then there is a good chance that the power source is responsible for the situation. If the power source is unstable, the power status of devices would fluctuate and that interferes with the recognition process. Unless you manage to address the instability of power sources, it’s tough to maintain a connection between your Samsung and all of its devices.

Issues With HDMI Cable 

The HDMI cable is the link between devices and televisions so issues with HDMI cable inevitably disrupt the recognition process. Because of that, if your Samsung TV fails to recognize devices out of the blue, one of your first suspects should be the HDMI cable. A couple of issues that the HDMI cable runs into in use have straightforward fixes. That being said, sometimes you may have to replace the cable to get your TV to recognize devices connected to its inputs like usual again.

Input Troubles

Needless to say, when the inputs act up, your TV is incapable of recognizing devices. For minor problems with HDMI inputs on televisions, you would be able to work out the solution on your own. Nonetheless, if you know little about televisions in general, it’s best to let the pros take a look at the inputs of your TV.


If nothing seems out of the ordinary with the hardware, you should consider the possibility that the software of your TV is at fault here.

Loose plug is going to prevent the flow of electricity from reaching the devices and the result is a recognition difficulty.

Switch To Another Power Source

Assuming that the devices appear ok, you must think about switching the power source that provides the devices with electricity. By using another power source, you could see if the original power source is the one that gives you trouble. If your TV recognizes the input after the switch, feel free to conclude that the original power source is bad.

Give The HDMI Cable A Look

Hence, if you wish to be thorough, it’s widely advised that you grab a cable replacement for your TV. Nowadays, you would be able to pick up HDMI cables at the local electronic stores.

Take A Look At The Inputs 

Over time, a lot of things from dirt to insects could cause troubles for the HDMI inputs of Samsung televisions. As a result, once it comes to Samsung TV not recognizing HDMI input, examining the inputs is a top priority. In quite a few cases, the recognition failure vanishes after people clean the TV inputs. Of course, you have to cut power to your TV before cleaning the inputs so you don’t get shocked.

Assess The TV Software 

On occasions, software errors would prevent television from recognizing devices connected to their HDMI inputs. To resolve the situation, you should turn your TV off and on, update its software, perform a factory reset, etc. Don’t hesitate to get in touch with the customer service of Samsung for in-depth instructions on software errors. The moment the software is free of error, your Samsung television is going to recognize HDMI inputs with relative ease.
