Quick question. I'm thinking of purchasing one of these: http://www.dell.com/ed/business/p/dell-u2414h/pd I have a number of adapters including Thunderbolt to HDMI. I've just tried it in my current monitor (BenQ XL2420T) and it wasn't quite as crisp as I would have liked. Is there a recommended method of getting the MBA display onto the monitor with maximum quality? Cheers!
