Short answer is
yes you can.
I have an SP3 and Chromecast, and it works - the SP3 works as well with the Chromecast as anything will.
Longer answer is that screen mirroring is the thing that the Chromecast does
least well. If you already have a Chromecast, you could use it for this, but it's not great. I'm also note sure how well the Chromecast 'travels' between different Wifi if that's an issue for you.
Note I have also read (but not tried) that Google Slides now has Chromecast support. If you can import your presentation, that would probably work better than screen mirroring.
If presentation is a key thing for you, the Microsoft WDA will likely be much more robust for screen mirroring.
For the things Chromecast is really good at (movies and music), it's much better than the WDA.
For anyone less familiar with the chromecast, what it does in order of effectiveness is:
- Acts as a dumb output device for video and sound 10/10
Here something like Youtube/Netflix/Pandora is sent a message from your SP3/Phone that says "Please play this Cat Video/Movie/Playlist to my Chromecast".
The video or song is then sent straight from the server to the chromecast, and your SP3 can turn off or leave the building as it's doing nothing. This mode uses no processing power or battery drain on the SP3, and performance is good because the media goes straight from the server to the chromecast without any extra processing.
Works really well for video and music, as a 0.1 or 1 or even 10 second delay is no big deal.
- "Cast This Tab" from Chrome 8/10
Can use on any website.
Unlike (1) you device needs to stay on.
I don't know if it actually sends the HTML to be re-rendered by a 'mini-chrome' renderer on the Chromecast, but it works well with very little lag.
- "Cast Screen/Window (Experimental)" 4/10
Will actually send the whole screen and whatever is on it from any program, this is what you'd need for presentations using say Powerpoint to present.
In this mode it sends screen frames, from your SP3 to Chromecast. In my experience it works, but has quite a bit of lag.
Possibly OK if you want to click to the next slide, and are OK with that happening 1-2 seconds later. If you want to actually use a mouse while looking at the Casted screen, it's very frustrating and I wouldn't recommend.
