Why won't the app cast to my TV?

  • Updated
Seeing a blank screen when you cast from the app to your TV, but hearing the audio just fine? Check this page: Why am I getting a blank screen with audio when I cast to my TV?


There are a few reasons why this might be happening...


Is your TV or plug-in TV device supported?

It is possible to cast from the CGX app to TVs or plug-in TV devices over Chromecast or AirPlay V2. If your TV or plug-in TV device doesn’t support Chromecast or AirPlay V2, you won’t be able to cast from the app.

Unfortunately, version 1 of AirPlay is not supported. If you're casting to TV via AirPlay, your TV will need version 2 of AirPlay (AirPlay V2).


Don’t have a supported device?

  • Google Chromecast devices connect to your TV’s HDMI port and can be used to cast from the app to your TV
  • Compatible Roku devices also connect to your TV’s HDMI port and can be used to AirPlay from iOS devices to your TV

Before buying any plug-in device, we recommend doing thorough research to make sure the device is compatible with your mobile or tablet and your TV. We know that buying a plug-in device may not be ideal if your TV isn’t compatible, as that's an additional cost. However, hopefully this can guide you to explore the options available to you and make an informed decision.


Are you casting from the app or mirroring your screen?

When you cast, you're instructing Chromecast or AirPlay to stream the workout video directly from the CGX app. This is the best method for quality because the video is fetched directly by the TV, reducing strain on your internet network.

Mirroring, on the other hand, uses your mobile or tablet as a mediator. Not only does your device stream the video, but it also has to relay everything visible on the screen to your TV. This double workload can put strain on your internet network, potentially leading to lags or disruptions.

Here at CGX, we recommend casting over mirroring. That’s because mirroring might be less stable because of the additional demand on your devices and internet network.


Are your devices connected to the correct WiFi network?

Both your mobile / tablet and your TV device need to be connected to the same WiFi network. This is how they speak to each other in order to send the stream from the CGX app to your TV.

You can’t cast to your TV via cellular data. If your WiFi network is weak in a certain area, your device might actually be depending on cellular data without you realising. A good step would be to switch off cellular data on your device and trying again.
