    Discovery Plus is the new streaming service in town and it seems to be creating quite a stir already. And why not, the platform offers all of Discovery's content over the past decades with over 55.000 shows in 25 different countries. Discovery Plus offers an introductory price for its service in many countries that is only $ 2 / month in some regions. So, if you're a fan of nature documentaries, but own a Vizio TV and are having trouble getting Discovery Plus, then let's take a look at your options.

    Can you watch Discovery Plus on a Vizio TV?

    Vizio TVs are a great high-end offering that includes a variety of built-in features that can help you watch and play on your TV. However, unlike most Smart TVs, Vizio doesn't include a built-in Android fork to help manage apps right on the TV. 

    Vizio instead uses its SmartCastOS which comes with integrated Airplay and Google Chromecast. This allows you to mirror your screen from virtually any digital device you own. So your only option is to cast Discovery Plus to your TV.

    Can you have Discovery Plus as a channel without broadcasting?

    Unfortunately, Discovery Plus is not a live TV channel, but rather a streaming service. This means that you will need at least a web interface and a working Wi-Fi connection at all times to access the service. Therefore, you will not be able to view Discovery Plus on the Vizio TV without broadcasting.

    How to broadcast Discovery + on a Vizio TV

    Broadcast is a simple Wi-Fi protocol that allows you to mirror one device's screen to another device as long as they support compatible protocols. Most Vizio TVs produced in recent years come with built-in SmatCast Os which can help you easily cast from a Windows device, Mac, Android device, or iOS device. Let's take a look at the procedure.


    • Your Vizio TV and the broadcasting device are connected to the same Wi-Fi network

    Guide to broadcasting from a mobile device

    The Discovery Plus mobile app is the same across all platforms. To cast your content on TV, you simply have to start playing a program you want to watch on the big screen. 

    Once launched, tap the "Cast" icon in the top right corner of your mobile device and select your TV from the next list of available casting devices.

    Guide for broadcasting from a desktop

    To cast from the desktop, you'll need to use Google Chrome. Simply download the latest version of Google Chrome and install it on your Mac or Windows desktop. Once installed, visit Discovery Plus and click on the “3 dots” menu icon in the upper right corner of the screen. 

    Now click "Cast" and simply select your TV from the next list. The desktop should automatically start casting the browser to the TV in no time.

    My Vizio TV does not have the SmartCast operating system

    There seems to be some confusion regarding the compatibility of older Vizio TVs with casting. Some older Vizio models are compatible with casting, but they simply did not use the Google-branded Chromecast product. This means that you will still be able to cast from your mobile and desktop device to your TV.

    A good way to identify if your old TV supports broadcasting is to use the remote to switch between inputs. If in addition to 'Input 1, Input 2 ..' and so on, you have the 'Cast' option, it means that your model is compatible with casting despite the lack of Vizio's new 'SmartCast OS'.

    However, if the "Cast" option does not appear on the input selection screen, you will need to opt for one of the third party devices listed below.

    My Vizio TV does not support broadcasting

    If you have used the method above to verify that your TV does not support broadcasting, the only way to watch Discovery Plus on your device is via an HDMI connection or by using a third party connection.


    Use an HDMI cable to connect the desktop to the TV. Select the appropriate screen in the screen settings. If you have a dedicated video card, you will need to select the TV via your video card control panel. Once selected, simply launch Discovery Plus in the browser to start watching immediately.

    Third Party Peripherals

    There are numerous third-party peripherals on the market that allow you to turn a normal TV into a Smart TV. Most of these devices come with a built-in Android TV fork and allow you to install Android apps on your TV itself. 

    This way you can directly install Discovery Plus and watch it on your TV. In addition, most of these peripherals of famous brands are compatible with the broadcast. This means you also have the option to cast Discovery Plus to TV from your mobile or desktop device. Here are some of the most popular utilities you can try to get Discovery + on your Vizio TV.
