Hi I'm a college student and am looking for an alternative to buying a new tv. I have a MacBook that has a nice enough screen and quite frankly why buy a new tv when you already have this nice monitor, right? So my question is if there is any way to use the monitor from my mac to watch tv, play xbox, etc. Basically plug in either a set of RCA Cables or whatever the case and view it on my laptops screen. I've been google'ing around trying to find a solution but I'm finding mostly outputs from the laptop (such as movies that are on the laptop and then viewing it on a different screen) or other weird video importing software which will mostly likely lag I would think. So if you've done this or are familiar with a way to do this I'd love some help in finding a solution, thanks.
