Chromecast, Samsung Smart TV, etc.

Currently, sending things from the cell phone to your Smart TV, Chromecast or streaming device is much easier than before. If you want to stream content from YouTube, Netflix, Spotify, Facebook, and many more apps, you just have to use the square “Cast” button on them. For photos, videos or files saved on the cell phone, use Google photos O Google Files, which also offer that button. There are also utilities to force the streaming of browser content, for example to stream movies online to your Chromecast or Fire TV Stick. But it is likely that on more than one occasion you have come across apps or games that do not have that “Casting” button, so that content cannot normally be sent to TV.

For those applications that do not have the “Transmission” button, your alternative is to clone the mobile screen on the TV. In other words, the cell phone screen is doubled on TV. Generally the most common solution is to use the Google Home app. You must open this app and the “TVs” available on the WiFi network will appear at the bottom (they are automatically scanned). Tap on “TV” and then on “Send my screen”. The audio and sound from the device will be sent to the TV.

Smart View (Samsung)

Apparently Google Home only detects “TVs” that support Google Cast technology. Therefore, it is likely that some “TVs” do not appear on it and you cannot mirror the cell phone screen. For example, this has happened to me with my Samsung Smart TV.

Fortunately my cell phone is also Samsung and these devices include a function called «Smart View«, Which allows you to easily share your cell phone screen on TV. Simply look for this function in the top panel of quick settings of your Samsung cell phone, tap on it and choose your Samsung TV to hook up.

If your cell phone is from another brand, it is possible that the manufacturer has integrated a technology based on Google Cast, Miracast or WiFi Direct to transmit the screen to the TV in a similar way to the previous cases. The name of the option may vary slightly. It should generally appear as Screen Mirroring or Miracast Display. Unfortunately I have not found an option that allows you to see the screen of an iPhone on the TV, unless that “TV” is a Smart TV with AirPlay support or it is an Apple TV.

Obviously, all this only works if your TV has casting technology (generally all Smart TV has it) or a streaming device connected to one of its HDMI ports, such as the aforementioned Google Chromecast or Fire TV Stick. If neither is your case, you probably have an old TV. If it has an RCA input (Audio and Video), you will need an HDMI to RCA adapter to transform the signal from the streaming device to the RCA signal that your TV “understands”.
