Present wirelessly with Chromecast in your conference room

Google's $35 Chromecast may be the simplest, least expensive way to present wirelessly from your laptop browser.

In late July 2013, Google launched an inexpensive device for wireless screen sharing: the $35 Chromecast. Billed as an accessory for your television, the Chromecast plugs into an HDMI port and is powered via USB or AC adapter. After a bit of setup, you "cast" video to the Chromecast from YouTube or Netflix. Android users may also "cast" music or movies from the Google Play store.

Business case

There's also a more serious side to the Chromecast. Chrome browser users can "cast" content from a single browser tab to the device, thanks to a free Chrome browser extension. You can cast a tab containing Google Docs, Sheets or Slides - or any web page, for that matter. This makes the Chromecast device useful in meeting rooms.

Here's what you need to know to setup and use the Chromecast at work.

Chromecast setup

You'll need:

  • Chromecast,
  • A nearby USB port or power outlet (to power the Chromecast device),
  • A WiFi network, and
  • A TV or projector with an open HDMI port.

If you connect the Chromecast to a TV, use the AC power adapter, that way, when you start casting, the Chromecast will power on the TV and switch the input selector to the Chromecast automatically. This feature requires HDMI-CEC, or HDMI Consumer Electronics Control, which most recent TVs support. Chromecast should work with any TV, computer monitor or projector with an HDMI input.

You can set up your Chromecast from a browser or an Android app. To setup from a browser, use the Chrome browser and install the Google cast extension. To setup from an Android device, install the Chromecast app from the Google Play store.

Once your Chromecast is plugged in and powered, wait for the Chromecast start screen to display. You'll then walk through four steps:

  • Selecting the device,
  • Identifying the device with a unique code,
  • Connecting it to your WiFi network, and
  • Naming your Chromecast.

Walk through the setup steps on any device by opening a browser to: http://google.com/chromecast/setup. Here's what the steps look like when using the Google cast extension from the browser.

The process is slightly different if you use the Chromecast Android app.

Chromecast is even easier to setup using the Chromecast Android app.

You'll need to repeat the setup whenever you move the Chromecast to a new network. Chromecast does not work on wireless networks that have forced login pages, such as those common on hotel networks.

Name the Chromecast something distinctive, such as "Chromecast Board Room", so you'll know which device to select.

Once setup, the Chromecast should be visible to other devices on the network. Any device can then "cast" to it. As of August 2013, there's no way to require a passcode before "casting" to the device, as may be done with Apple TV. However, both devices must already be on the network for casting to occur. (Yes, random employees with access to the same network can cast indiscriminately. But if that happens, I suggest you have a personnel issue, not a security issue.)

Presenter setup

The presenter needs:

To present, open your browser to the content you want to share. Click the "Google cast" extension to begin casting your tab to the Chromecast.

Chromecast meeting tips

Tab-casting sends the contents of the browser tab to the Chromecast. Resizing the browser width changes the width of the displayed tab.

But Chromecasting is not full-screen mirroring. The audience sees only the contents of the shared browser tab. Presentations that include opening links and highlighting content both require preparation.

When Chromecasting, links that open a new browser tab are a problem. Since Chromecast only displays the current tab, not the new one, the audience won't see content in the new tab. The presenter needs to switch to the new tab, then start Chromecasting from that tab. Problem solved.

There's also no easy on-screen way to point at things: the presenter's cursor location doesn't display. For many presentations, this won't matter. If pointing is needed, a handheld laser pointer works.

But since Chromecasting is not full-screen mirroring, there are at least two benefits.

  • First, only the content of the browser tab is shown. The presenter's desktop, bookmarks bar, extensions, URL box, and other tabs do not display. This eliminates much of the awkward fumbling-around, trying to hide bookmarks and tabs too often encountered with inexperienced presenters. The audience simply sees the contents of a single tab.
  • Second, the presenter isn't restricted to only looking at slides; they can look up information during a meeting. Need to look up pricing? Open a spreadsheet. Need to refer to an email thread? Switch to another tab and search email. The Chromecast device will continue to display only the contents of the browser tab being cast. The audience won't see other information. Presenters can use their laptops to fully participate in meetings, not just present. That's a big change from being forced to only page through slides!

An excellent value

For $35, the Chromecast offers a simple, inexpensive way to present wirelessly. If your organization uses Google Apps, the Chrome browser, or Chromebooks, the Chromecast is a useful addition to your meeting room toolkit.

Nice walk through with a huge omission. You mention the conference room setting, which implies a business WLAN is in play. Most business WLANs do not support multicast, and use Enterprise security- both of these make Chromecast a living-room quality device at best because it can't do Enterprise security and needs multicast. I love mine- but to imply its a good fit in the business setting is just wrong.

What if your TV has USB? Can it be used to power the Chromecast?

And, in news today, Google released a Chromecast app for iOS devices: https://itunes.apple.com/us/app/id680819774.

The app makes it easier to setup and manage the device from iOS.

I'm curious: are any of you using Chromecast for work? Or is it strictly a home entertainment device for you?

@Adam S Yes, if your TV has USB you can the USB to power the Chromecast.

With USB power from the TV you lose two things related to HDMI CEC:

1. the ability to automatically turn on the TV when selecting Chromecast and,

2. the ability to automatically switch to the Chromecast input.

So, yes, it will work, but if your TV supports HDMI CEC, I recommend using a power source OTHER than your TV. Auto-on and Auto-input switching is handy!

My family is just using it for home. I have and iphone and was wondering if it's possible to use other apps with it. Not just netflix and YouTube. It would be great if I could show pictures and videos from my phone and a lot of games would look really cool.
