1. Samsung S9 screen mirroring, using Wi-Fi Direct.

This method is only for TVs built-in support for scree-mirroring or Smart TVs. In case you don’t have one, please proceed on reading from method 2.

Smart TV owners can mirror their S9 screen using a conventional-wired option through one of its HDMI ports, which I´ll explain later, but given the enhanced capabilities of smart devices, it is better to cast, wirelessly, the content displayed on your S9 screen without using cables, adapters and even bypassing your Wifi connection.

For this purpose, your Samsung Galaxy S9 should have installed the SmartView app, which allows you to send content from your mobile device to most TVs that allow screen-mirroring.  In case you don´t have it installed, download it here:

Then, do as follows:

Step 1:

On your Smart TV, please turn on the wireless capability or Wi-Fi direct, to make it visible to your S9. Please refer to the user manual of your tv device on how to do so.

Step 2:

On your S9 go to settings or slide your finger down from the top of your screen, to display the pull-down menu. Turn on the Smart View Icon.

Step 3:

Select the device you want to mirror to. If you did step 1 correctly, your Smart TV name should appear on the display list of devices available.

Step 4:

Finally, a message might appear on your Smart TV requesting you to either accept or decline the connection; please select the option, using your remote control, that will allow your S9 to send its screen content to your TV.

And that´s it. You´re all set to start having a larger picture (literally) of the content shown on your S9 screen.

2. Samsung S9 screen mirroring to a LED TV, using Chromecast

For this, you need to have an Internet wifi connection to which both your S9 and the Chromecast streaming device, can be connected to. We advise you to go for the latest version, the Chromecast Ultra, but the previous version of this device is also available, which might also work for you.

Step 4:

Download the Google Home app to your S9:

Step 5:

Open the Google Home app and follow the instructions. The app will guide you through the installation process of your Chromecast.

Step 6:

Once Google Home is installed and configured, use the cast icon now displayed in most apps installed on your phone (such as youtube, Netflix, etc) and start mirroring your favorite content from your S9 to your TV.

3. Samsung S9 screen mirroring to a LED TV, without Wifi

For this procedure, you´ll need a streaming device such as the ScreenBeam Mini2, in order to give your LED TV the screen-mirroring capability. We recommend this option only if there´s no wifi connection available otherwise, we advise you to use Chromecast instead, as explained in method 2.

Once you’ve got the ScreenBeam Mini or similar, do as follows:

Step 1:

Connect the ScreenBeam Mini2 to the HDMI port of your TV.

Step 2:

Connect the micro-USB end of the power cable to the ScreenBeam Mini2 and then the power adapter to the wall plug. ( The device can also be fed from any USB port available on your TV)

Step 3:

Turn your TV on and press on the source button of your remote control. A list of input channels will be displayed on your tv screen. Select the input associated to the HDMI port you plugged the ScreenBeam Mini2  into.

Step 4:

On your S9, go to settings or slide your finger down from the top of the screen, to display the pull-down menu and select on the Smart View Icon.

Step 5:

Then select the device you want to mirror to. If you did steps 1,2 and 3 correctly, your ScreenBeam Mini2 should appear on the displayed list of devices available to connect with. Select it and that´s it, you´re all set to start watching your Samsung Galaxy S9 screen on your TV.

4. Using a wired connection to mirror your Samsung S9 to a LED TV

If you don’t have a Smart TV or any of the gadgets that can convert your LED TV into a smarter one, then the wired option is perhaps the most suitable for you.

In this case, you’ll need your TV (with an HDMI port at least), an HDMI cable, a USB-C to HDMI adapter and of course your Samsung Galaxy S9.  You’ll see that this method is very simple and perhaps, the hardest part would be to decide which HDMI to USB-C adapter to purchase.

Among the many choices, there are to buy, the Samsung Slimport HDMI to USB-C will work just fine for you.

Tip: Instead of getting the HDMI to USB-C  adapter, you could also buy a USB-C to HDMI cable instead. It does the trick and can save you a few bucks.

After you’ve got all you need to bridge both devices, do the following:

Step 1:

Connect the HDMI end of your cable to your TV.

Step 2:

Then, connect the other end of the cable into the HDMI side of the adapter. ( If you went for the HDMI to USB-C cable option, don’t mind this step)

Step 3:

Finally, plug the USB-C port of the adapter (or cable) into your Samsung S9 phone.

Step 4:

Turn your TV on and press on the source button of your remote control. A list of input channels will be displayed on your TV screen. Select the one associated to the HDMI port you plugged the cable into and voila! The content of your Samsung S9 screen should start mirroring on your TV.

Finally, you can also screen mirror to other devices such as projectors and monitors with different input ports since the USB type C port of your S9 device is compatible with VGA and DVI standards. After you get the right adapters (or cables), follow the procedure as explained in method 4.

Conclusion

There is a variety of methods to screen-mirror your S9 to another device. The decision on which method works best is ultimately yours and it will depend on how smart your device is, the availability of specific wifi settings, the type of input and output ports of both devices and also on your budget.

The smarter your TV is the more wireless you can go. But in case you don´t own a smart one, it´s still possible to mirror your Samsung device to your TV as long as it has at least, one HDMI port.

Wired-screen-mirroring through a USB-type-C-to-HDMI connection, as explained in method 4, might be beneficial in terms of avoiding lagging and improving the frame rate of your transmission. But it won´t allow you to move freely and to change content from wherever you want. In that regard, the wireless options, like in methods 1,2 and 3, are preferable.

If after trying any of this methods you´re still having trouble connecting your S9 to a TV, please take a look at this article on how to fix screen mirroring that is not working.

  1. Hi, thank you for this guide, but casting specifically from the S9 to a Chromecast fails invariably – apparently “the device (S9) has not been optimized” for this service – as we’re informed by a message in the Google Home app.
    What a shame, that a flagship Android device from this market leader has not been optimized to work in the Google ecosystem…

    1. That’s a bummer. However, it works well with my Note 9. If I’m not mistaken, both our devices were released in the same year. Try updating your device’s software or remove junks and clear unnecessary cache to help with device optimization. Hope this helps.
