OK honestly lets be real if my native mode is 1440 by 900, and i get a larger screen like a 27 inch samsung , the screen will prob look blocky, and not that sharp because of the increase in size, i did this hoooked up to my 720 p 40 inch tv and it looked blocks and crappy. I dont know if a 27 inch will do the same, i dont want to have any loss in sharpness or display.
did that make sense?
It seems that the only option to have a large screen off of a laptop would be
1) thunderbolt no loss in display *but to expensive
2) using HDMI with a newer will retain sharpness
3) a mac mini w a samsung display
4( use macbook pro 2007 and just suck it up with bigger icons and less sharpness with a larger display. using DVI
