Chromecast for Showcase and Showcase VR

Matterport Showcase is a fantastic platform for presentations. Why not make it Chromecast compatible?

Matterport Showcase VR is a fantastic platform for the person with the goggles, but it's hard to know what someone is looking at. What if you could cast the image too?

I believe that the ability to Chromecast is a swiss army knife tool for unlocking potential.

I believe that the 'dualcast' feature of the Google Cast SDK should not be too difficulty to implement.



  • Super cool idea, @Chris Hickman!! We are scrambling to keep up with all of the great VR ideas coming this way, but we're reading all of them. More soon! :-)

  • I was able to setup and mirror the Gear VR view using the Chromecast dongle. There are a few work arounds to get it to work smoothly. If you do not complete these steps the screen sharing will work for about 2 to 3 seconds and then the video on the television freezes.

    Note: I am using the Samsung S7 Edge

    Steps to get the screen mirroring to work smoothly:

    • One: You have to enable Developer Mode on the Samsung S7
      • After you get to the settings go to the “About device” and select on the “build number.” (You have to tap build number 4 or 5 times to get it to enable) After a few taps you'll see the prompt and then tap four more times and you're done. Then select the back button and head back into the original basesettings menu on the Samsung Galaxy S7.
    • Two: You have to enable “Simulate secondary displays”
      • Go into Developers Options(which doesn’t show up until you complete step 1) on your phone. Look for "Simulate secondary displays" under the Drawing section. Change that to "720 x 480 mdpi (secure)"A small window will appear showing a second screen but will disappear when the Gear is docked. It does not disappear when you disable the Gear VR service but for Google Cardboard apps its stays out of your FOV.

    A few more notes:

    Using the phone in this configuration causes the phone to warm up very quickly. Between the VR App and the Chrome cast the phone is maxed out. I would definitely work to limit the time frame the phone is in use. i.e. I would have multiple phones maybe two cooling off while one is working.

  • That is a great idea. I've always found in my 25 years of VR operation that for every person who wants to try VR there are 10 who won't but are equally interested in what is being seen by the "immersed" person.
    Being able to replicate the view of the Gear on a second screen is a great idea and is a sure thing for pulling people to your booth at a tradeshow or any other public demonstration.

    I'm off to investigate. :-D

  • Wow - that's awesome! This would totally be worth Matterport posting in their official FAQ as a solution! I'm sure a LOT of people would love this native feature as it doesn't require a 3rd party app.

    Don't do this with a Galaxy S7 Note though. Dangerous.

  • Does it matter which version of Chromecast we use @jrbatchelor ?

  • Does it matter which version of Chromecast we use @jtbatchelor ?

  • Does it matter which version of Chromecast we use @jrbatchelor?

  • I tested it on on a brand new Chromcast dongle. Don't know about previous versions. But if you try it out please post results.

  • Chris I would definitely NOT use this with a Samsung Galaxy Note 7. With both apps running it can cause the phone to overheat. I ran into this in my testing. No batteries caught fire but the phone did give a overheating warning. The whole screen turns a shade of red. So this is my warning to anyone using any Samsung phone in this configuration. USE AT YOUR OWN RISK.

  • @jrbatchelor.

    Just received my Chromecast Ultra and followed your steps as above and while the Chromecast app on my Edge 7 is transmitting to the screen (natively) when I start the Oculus app nothing is transmitted.
    Am I missing something? Should I close the Chromecast app, thoughts?

  • First I launch the app from a QR Code for the space, not from the oculus app. The GearVR also has a sensor that has to be covered while casting to the screen, or it will not cast to the chromecast. I usually cover it with my finger while looking at the TV.

    Another problem that I had was if I plugged it into my monitor, the monitor would show the startup screen for a moment then would just go black. I am assuming that the monitor cannot support the resolution that the Chromecast was sending to the monitor. So I figured out that I had to plug into my Panasonic Plasma. Once I did this I was able to get the phone to send a signal to the television. An added Plus: After a few seconds of casting the television sensed that there was a 3D signal and asked if I wanted to switch to 3D. When I selected yes it merged the two views into one and created a monocular view on the TV. I can then put on my 3D glasses for the TV and see the model in 3D on the TV. It was cool. I'm going to complete a video on this soon so everyone can see how it works.

  • Here is a picture of the Proximity sensor location you have to cover:

  • One question: when you "Launch VR" does the screen immediately go blank or does it only do it after you put the phone into the GearVR?

  • You didn't mention I needed to cover the proximity sensor. ;-)

    Will it only start from the QR code? In which app do you scan the code? A QR reader or somewhere else? Maybe we need that video, you're obviously brighter than me ;-)

    What I did was follow your instructions regards the phone so I have the screen with the small secondary screen.

    I have the Google Home app running and transmitting the background image to the Chromecast attached to my monitor. I then plug the phone into the Gear HMD and the Oculus Home app launches but nothing is being transmitted to the screen.

    I guess I'm missing a vital step in there?

  • I use "QR Extreme" from the Play Store here:

  • I uploaded a new video about using the Samsung Galaxy S7 Edge, Gear VR, Chromecast connected to a Panasonic Plasma 3D TV here.

  • I uploaded a new video about using the Samsung Galaxy S7 Edge, Gear VR, Chromecast connected to a Panasonic Plasma 3D TV here.

  • After being side-tracked with other things I finally got this working with my Chromecast Ultra and it works brilliantly. I got it to fire up from just opening the app as well as using a QR code. Also it appears to me that the secondary screen image on the device disappears from both the Cardboard app and the Gear app now.

    I assume to do the same with an iPad we'd need to use Apple TV?

  • Have you tried it with a 3D TV. If you use a TV that accepts a 3D HDMI Signal you can make the two eggs converge and create a single portal on the TV which can then be viewed using the 3D glasses for the TV. Pretty cool... I'm wondering if Apple TV would have the same functionality? If you try it out on a 3D TV let me know how it works out...

  • No we don't have a 3D TV, thought they were a bit expensive for what turned out to be a bit of a 'flash in the pan' novelty for general usage although I do agree it must look cool.

    I don't have an Apple TV unit so was sort of asking the question if anyone had tried using one. :)
