I have a 13inch "Early 2014" MBA that has a Thunderbolt socket and I would like to purchase an external monitor (minimum size 24inch) that I can use as a larger screen. I have been looking at WQHD screens with a resolution of 2560x1440, but I am confused by the specification of the MBA (which tells me that the resolution is 1440 x 900) and whether the MBA will be up to the task of filling a 24inch screen with fine, crisp detail. I intend to use the screen for CAD, graphics, internet browsing and general home office functions. Can someone tell me if the resolution figures illustrated in the MBA specification page means that I won't be able to get a higher resolution than 1440 x 900 on an external monitor? If this is the case, I am very likely to be disappointed by the results. Thank you.
