Hexus published a review on the HP EliteDisplay E243d
A quote from the article:
The ultimate Ultrabook accessory? Remember how awkward it used to be connecting a laptop to an external display? Each device would typically need a power brick, you'd have to fasten a DVI cable on both ends, a 3.5mm audio cable was necessary if you wanted sound, you may as well add an Ethernet cable while you're at it, and if you really wanted to get things done you would set aside a couple of USB ports for peripherals. I can remember creating that sort of setup myself, and the mess of cables was so severe I recall having to physically shave one side of the DVI connector in order not to obstruct the adjacent USB port.HP EliteDisplay E243d Review
Fun times, but technology has moved forward and with today's laptops offering immense power in ultra-thin form factors, we're at a stage where docking monitors make a whole lot of sense for a wider range of customers. That's where the HP EliteDisplay E243d comes into play.
