What you see above is a 11.6" Lapdock being used as a secondary, portable extended display for my 15" Macbook Pro Retina.
A few months back, I reviewed a cool gadget, a
15" MHL HDMI portable monitor from GeChic which can be read here. Yes, it was a cool gadget but a bit bulky and pretty pricey for something that may not be used on regular occasions. I then turned my attention to the Motorola LapDocks because they have been great in the gadget scene. First, I got myself a newer LapDock 100 and that didn't turn out so well. The newer docks have been made more difficult to use as a dummy monitor. Well, after a few weeks, I ended up with the original Motorola Atrix Lap Dock. And I have to say, I am very pleased. These are still selling for $60-80 which, in my book, is a STEAL of a bargain!
To use this as a portable HDMI monitor, all you need are some cables, couplers and adapters. The device has two ports: Micro-USB male and Micro HDMI-D male for video. To use as video, you need to get a female Micro HDMI-D coupler. Then you connect to anything that can use HDMI which includes displayport, mini-displayport, and Thunderbolt.
