So I'm getting a new desk to declutter my apartment and I won't be able to use my second monitor. My question is if I use a netbook as a display, will it use processing power? if it does I do have another one, just thought it would be nice to have a smaller one not taking up so much space. Not sure if this is the right category to post this but I thought i'd try.
