Hey everyone,
I've always hated the fact that in order to watch a video on YouTube in fullscreen you couldnt use your 2nd monitor. This drove me nuts, and recently I started looking for a solution, which I figured had to be out there.
Needless to say, it was not easy to find at all! Most of the solutions I found were dumb, and more work than they were worth.
Finally I stumbled upon a very very easy solution, though I dont have the website handy to give a reference.
Step 1)
Go to a video on YouTube, in this example I am going to use
Step 2)
Modify the link slightly (this works with ANY video on YouTube)
http://www.youtube.com/v/eBGIQ7ZuuiU
Step 3)
Enjoy your video!
You can also press F11 if you want to toggle between fullscreen mode (in your browser, not the video itself) which will increase the size of the image slightly.
Hope someone else finds this as useful as I did!
Regards,
