Smartphones can easily be connected to the television, for example to view pictures or videos from the last holiday comfortably on the television at home or to transfer content from the various streaming services from the cell phone to the television screen.From a technical point of view, there is no silver bullet.Much more different approaches are possible.Although the two top dogs in the field of mobile operating systems - Android and iOS - differ in their functionality, streaming on the TV is possible with both software solutions without any problems.Even devices running Microsoft Windows Phone usually allow this feature.However, should complications arise, various hardware supplements can help.These include Google Chromecast, the Fire TV Stick from Amazon or Apple TV.At least these supporting devices guarantee a perfect connection between smartphone and television.Wired or wireless connections are available to connect a smartphone to the TV at home.The operating system plays a subordinate role here – as long as it is a reasonably up-to-date version.In addition, the hardware should not be from the day before yesterday.Although streaming does not require high computing capacity, a mobile phone at the performance limit is of course not ideal.It may therefore help to retrofit here.For example with one of the numerous mobile phone deals that are easy on your wallet.Google's Android operating system basically allows two approaches to display smartphone content on the television.The first option is to use a cable using connection standards such as MHL, Slimport, Mini DisplayPort or Micro HDMI.In order to use this type of transmission, all you need is a suitable cable, which is usually available in specialist shops for around 10 euros.A special app is not required.After that, all you have to do is switch the input signal to the corresponding HDMI port on the television.Those who prefer a wireless connection can use technologies such as DLNA or Miracast.In most cases, modern smart TVs and the latest generations of smartphones have at least one technology solution.In some scenarios, downloading a smartphone app like BubbleUPnP or AllCast is necessary.In this context, it is essential that both the Android device and the corresponding television are dialed into the same WLAN network.The transmission of smartphone content to a television is of course also possible with an iPhone, but unlike the competition, Apple limits itself to two or three methods.If you are looking for a wired solution, you will have to limit yourself to a Lightning Digital AV Adapter, which is manufactured by the US company itself.This makes a connection via the HDMI connection of the television possible.A wireless connection works with Apple devices via various apps.Suitable applications are, for example, iMediaShare or TV Assist, which can be downloaded from the App Store.The individual applications enable simple transmission of multimedia content from the iPhone to the television.A single shortcoming can sometimes be the resolution, which lags behind the original content in terms of quality.Apple TV can help.The streaming box can be connected to the TV via HDMI and then enables coupling with the smartphone.With its Chromecast smart TV stick, Google provides a direct solution when it comes to streaming.To do this, the stick must first be connected and the installation of the Google Home app started.It is important that the smartphone is in the same WiFi network as the Chromecast.After the installation has been completed, the app must be started.Here you will be asked to confirm the Google account and grant permissions.Once this step is done, the Chromecast device search must be initiated.Once the corresponding smartphone has been identified, it can be set up.Finally, the region, room and WLAN must be selected and the password entered.The setup is complete and the content of the mobile phone is ready for streaming.The retail giant Amazon has been offering the option of transferring content from an Android smartphone to the television for some time.The Fire TV Stick makes it possible.Just like with the Google Chromecast, the connection criteria are an HDMI input on the TV and Internet access.For setup, the stick must be plugged into the HDMI port and a corresponding input channel must be selected.The supplied remote control is paired with the stick and allows for easy operation.If the smartphone is in the same W-LAN network as the TV.If this is the case, the menu item “Duplicate display” must be activated via the Fire TV menu under “Sounds and screen”.Available smartphones are then searched for and listed.To start the so-called "Screen Mirroring", the device in question only has to be selected and confirmed.If the connection between smartphone and TV is successful, not all content can be displayed easily.Some services prevent this function.While DAZN, for example, allows the content to be streamed from the cell phone to the television, its competitor Sky Go denies this function.It is therefore necessary to check in each individual case whether the respective provider meets the relevant requirements.
