Watching YouTube video full screen while working in other monitor

Can someone please update this thread? Its really unbelievable that you cant have a youtube video fullscreen on your second monitor and continue to work on the primary one.

Please is there any fix or workaround for this?

Thanks

Thanks for you answer Swankboy, I have configured spaces now and added "desktop 2" however when I put a fullscreen video on "desktop 2" then I get the same problem, grayed out screen on the other monitor.

How are you doing it?

(Pd: my second monitor does not show menu bar its just an empty desktop.)

Try this.

1. You must have separate Spaces set in System Preference - Mission Control. If you don't both displays are treated as one extended display similar to Lion and Mountain Lion arrangement, causing one display to grey out when using Full screen modes.

2. Launch or move your browser onto the display you want the video to be on.

3. Put the browser into Full Screen mode by clicking on the diagonal arrows at the top right of the browser window.

4. Navigate to Youtube and find your desired clip.

5. Put the clip into full screen mode, by clicking on its icon within the video window.

The video shoud be on that display in full screen, no menu bars or Dock should be visible, with full access to the other display.

It sounds like Chrome has not implemented Full Screen properly then, or as swankboy states, only particular video formats cause the issue. I don't use Chrome myself, but instaling it here and briefly trying it, seemed to work OK, but my test was very limited.

If you come accross one that does not work as expected in Chrome and then view the exact same in Safari, does it work correctly in that browser? If so, it is more likely that it a Chrome specific implementation issue, rather than an OS X implemetation.

Ensure that you are using the latest version, and do you have any extensions installed into Chrome that may be effecting it's behaviour.

If Chrome has any forum support pages, you may try looking there to see if others have the same issue and if they have a solution.

It is possible that its also graphics card related and if Chrome takes that into account. My test was on a 2008 Macbook with NVIDIA GeForce 9400M.

I just noticed that it happens only with certain videos.. Its very strange.. Please try it yourself, for example:

When I put this video on fullscreen nothing happens with my main screen and I can continue to use it:

When I put this video on fullscreen, my main screen get greyd out and its not usable:

Im using Google Chrome latest version and my mac is a mid 2011 mac book pro running max os x 10.8.5

Thanks,

Hi, I just re-read you previous post.

You said,

Im using Google Chrome latest version and my mac is a mid 2011 mac book pro running max os x 10.8.5

I presumed that you were using OS X 10.9.x as we are in the Mavericks (10.9) forum area, not the Mountain Lion (10.8) forum area.

This changes things a little.

In Mountain Lion, Apple's implementation for multiple displays is a little different to Mavericks, where both displays share the same 'space' so it is an extended display setup. Mavericks allows each display to have its own space, thereby allowing each dislay to act independantly of each other. This is where I did my brief test.

Due to Mountain Lion's limitation, I think what you are seing is expected behaviour. Any Full Screen app will result in the other display to be greyed out.

In Mountain Lion, if you put the application into Full Screen mode, using the diagonal arrow icon at the top right of the application window, your second diplay is greyed out. This does not happen in Mavericks when displays are set to have different Spaces in System Preferences - Mission Control.

I suspect what is happening with videos, is that the full screen icon in the video window is not a true Apple full screen activation, but rather a fill the whole screen implementation, so would be treated differently by the OS.

It looks like the same behaviour can now be seen for ALL videos watched on youtube from Chrome.

There is no differentiation as it was a few weeks ago. (Probably based on codec)

Now any video you watch in youtube with fullscreen in chrome will basicall make use of a "space".

Solution: use Safari if you want to keep working on the other monitor.

Yes, AFAIK you can't go full screen and use the second monitor.

I don't use fullscreen but I just tested and as soon as I go full screen on any app the second display goes gray.

I don't use mirroring, maybe Spaces would work better for you?

Thank you,

What Im doing is opening another browser program to view videos in the external monitor. Safari seems to work well. It looks like the problem happens only when using Google Chrome.

What happens if you what the same in Safari?

No, only in Chrome..
