I am building a new computer and just wondered if it's possible to play a full screen or full screen windowed game on one screen, and watch a movie or have the internet open on the other? How would I set this up if it's possible. I'd probably need sound from both monitors if possible, both going through the same output (headphones connected via USB)
Yes it would work but if you are playing a game, chances are your cursor would be locked to the game so you wouldn't be able to interact with the second screen without Alt-Tab'ing. I am waiting on a second monitor to do just as you intend ^^
You' need to plug both monitors into your GPU go into Windows 'Screen Resolution' Page or Cataylst/Nvidia Control and select 'Extended Desktop'
