I am currently needing 2 screens, and have been offered 2x 23" screens (1x 2006 and 1x 2008) for £400 for both. I intend them to be run off my macbook pro 15" i7 16gb Ram (early 2011), which has the thunderbolt port. I was wondering if there is way to link the two screens together and to get the full resolution out of both? I've done some research and found that I can get a Mini DisplayPort cable and a USB 2.0 graphics adapters for the other- but this would not give me full resolution. is there any other way of doing this? or if i buy all the additional cables, is it more worth me buying the new Apple 27" thunderbolt screen, than risking the old expiring? as I will be using the screens for work purposes, so need to be hardy, as they will be in use a lot.
