Is using Keyboard and Mouse on Chromecast casting PC possible ?

[NPO]

Hello,

I would like to use a Chromecast with my projector to stream my PC as I don't want cable running on the floor.

I have seen that it is doable to use a USB-C hub to connect a keyboard and a mouse to a Chromecast and use them in the Google TV interface.

If i stream my PC through the web browser, would I be able to use the keyboard and mouse to control my PC ?

Sorry for my english, it'snt my mother tongue.

Thanks in advance,

NPO

You would not be able to use the mouse and keyboard connected to your Chromecast to control your PC.

In your case, you would keep the keyboard and mouse connected to your PC and cast the PC screen to your Chromecast.  Anything you do with your keyboard/mouse will affect your PC and be reflected on your projector.

Keep in mind that not all apps work with mirroring and there can be lags so make sure you test in advance if you are doing a presentation.

Hi,

Thanks a lot for your answer @Byteguy 

I was thinking of using it to stream movies and play videogames.

Here are a few questions i got :

Does the latency is constant or is it variable ?

Does the 4K version is more responsive ?

Any desynchronisation between audio and video ?

Any experience with streaming movies and videogame ?

Best regards,

Streaming always works BEST if you are using a site that is cast-enabled (has the casting icon).   Like Netflix, Google Movies, etc.    Those send the data directly from the service to the Chromecast and do not rely on another device to handle the stream (which causes the latency).

Also, you will find that mirroring may not work on a lot of movie sites.  They often use tricks to avoid the screen being recorded or re-directed because they are trying to fight piracy.

Mirroring is processor and network heavy.  Your computer has to do the work to show everything on your screen, AND then capture the screen, AND then recode the screen for Chromecast, AND then push the data to the Chromecast.  That is a lot of work to do while also trying to keep a video game or movie running smoothly.

The best advice is to give it a shot and see how it works for you.  You may be forced to run a cable after all.
