Chromecast and beamer: that’s how they (not) work together [+ uitleg]

The Chromecast and beamer go well together. However, there are things you should take into account and you can read all about that in this article. For example, you have to arrange something for the sound and it is possible that your beamer does not have an (available) HDMI port.

Connecting Chromecast and beamer is in principle very simple. If your projector has an HDMI connection, you plug the Chromecast into the port, provide it with power (via USB or a plug), set everything up and you can immediately start using cast.

Even easier: nowadays there are beamers that are equipped with Chromecast built-in. Then you don’t have to do anything with an extra Chromecast model and everything works very easily via the beamer’s operating system. Sometimes such projectors Android TV on board like this and this one.

Chromecast and beamer: connect

For a Chromecast you need a number of things and, depending on the model, also an adapter.

However, you may run into problems. Perhaps there is a mini HDMI port on your beamer or else a version without hdcp (high-bandwidth digital content protection) on-board. Without hdcp, the Chromecast will not work completely, so you have to solve that first.

Without hdcp you run into problems with both audio and video. You can easily solve this by buying an HDMI splitter. You then connect the Chromecast to the beamer for the image and a speaker system or receiver for the sound. You may also need a mini HDMI adapter.

That mini HDMI adapter provides a bridge between the HDMI cable and the HDMI port that is too small. It is an extra device between the Chromecast and the beamer. The more adapters you use, the more it affects image quality – so this is something you ideally want to avoid.

Chromecast and beamer: the audio

In the field of audio, things can therefore also go wrong. You may not hear anything at all or else you may have creaky sound due to built-in low power speakers. The first problem can therefore be solved by means of an adapter.

You must then be able to connect the beamer to an external sound system. This is possible, for example, with bluetooth speakers, but a better option is to connect speakers via the old-fashioned 3.5 mm connection or USB port. Otherwise, you may be able to arrange something with an HDMI cable.

But then you have to be sure that the Chromecast transmits the audio properly and that the beamer can handle it. If your beamer cannot properly process the sound signal from the Chromecast, you will need an extra adapter as described above.

The solution we mentioned earlier is therefore an HDMI splitter, but such an accessory is also called an audio extractor. So if you google for the options, those are the words you should search for. You can find some extra advice about this on Reddit, for example.

Chromecast and beamer: check settings

Once everything works, it can’t hurt to check the settings of the beamer or projector. You would do well to first go to the channel of the correct HDMI port. If your beamer doesn’t have an HDMI port, you’ll need the channel from another opening.

By the way, you can simply connect the Chromecast to a different opening connection. You do need an adapter for that. As with a monitor, this can involve different adapters; it just depends on the options of your projector. For example, consider an RCA or VGA adapter.

Anyway, when you’re on the right channel, check the settings regarding color correction, white balance, high dynamic range, resolution, projection distance, picture modes and keystone correction. If you are not familiar with those terms, check the manual of your projector.

You check those settings to ensure good image quality while watching. Because if you decide to use a Chromecast and beamer, make sure that the image quality is at a high level. Regardless of the source device on which you choose the content.

Chromecast and beamer: Set up Chromecast

After all those steps, you can install the Chromecast. You should have already physically installed the Chromecast, so we can immediately proceed to the digital installation via Google Home. Make sure that your smartphone or tablet with that app on board is connected to WiFi.

If the Chromecast has not yet been installed (and you are using it for the first time), installation instructions will be shown on the screen (of the beamer). If that is not the case, you can arrange this directly via the Google Home app, by tapping the plus sign at the top left.

Now press Set up device and New device and follow the steps here to connect the Chromecast to the Wi-Fi network. The steps all speak for themselves in the end; most importantly, the Chromecast connects to the same Wi-Fi network as your smartphone or tablet.

In addition, it is a matter of choosing and casting content to your Chromecast that is linked to the beamer or projector. You can cast different types of content, from apps as Netflix, Disney+, Videoland, Spotify and Google Stadia. In short: plenty of options and choices, fortunately.
