I noticed today the Dell UltraSharp U2410 supports Picture in Picture functionality and this got me to think about the use of this functionality in a PC monitor. I can see the benefit in a television as you can watch one channel and have another channel inside to see when something eventfull happen there. However I cannot really think of how this will benefit a pc monitor as you can already do this by opening multiple windows. I suppose you would just be able to have the non-active window in front. Are there more to it that I am missing here?
