Anyone who uses two or more monitors is well aware of a common annoyance with YouTube videos: you can’t watch them full screen and use your computer at the same time.

The problem is of course clicking on anything on the second screen makes the video instantly shrink back down to regular size.

For those of us who like to watch full-screen video while playing online poker, this is certainly an annoyance. So here's a quick tip which many of you may not know (I know I didn't until recently).

First, find the video you want to watch. Say this:

http://www.youtube.com/watch?v=8v_tPPbvKRs

Now, click the arrow above the video on the right side:

If you want to be a super nerd, you can do this manually as well by editing the URL string. First, take the URL of the video you want to watch:

http://www.youtube.com/watch?v=8v_tPPbvKRs

Now, you need to delete "watch?" and change the = to a "/". This will result in the URL looking like this:

http://www.youtube.com/v/8v_tPPbvKRs

Hit Enter. As you can see, the video will automatically fill up the entire browser window. Maximize the window and you have it almost full screen.

To get rid of everything but the window (making it almost entirely full screen) you want to hit F11. That will hide everything but the viewing window.

Note: If F11 doesn't work, it's because the video is hijacking the controls before they get sent to the browser. Open a new tab (If you can't figure out how to do that, hold down Ctrl and click once on the home icon), then hit F11 when viewing the new tab.

Now you're wondering how to get back to the video, since you've lost your controls and are on the wrong page. Hold down Ctrl and hit the Page Up button. This will move backwards one tab.

Bam! Full-screen YouTube video without taking over your comp.
