You can connect the RasPi HDMI connector directly to an HDMI monitor using a<br />
standard HDMI cable.<br />
Motorola Atrix Lapdock<br />
A number of people have used a Motorola Atrix (http://en.wikipedia.<strong>org</strong>/wiki/<br />
Motorola_Atrix_4G) Lapdock to add a screen and keyboard with trackpad to RasPi, in<br />
essence building a RasPi-based laptop computer. Lapdock is a very clever idea: you plug<br />
your Atrix smart phone into Lapdock and it gives you an 11.6" 1366 x 768 HDMI<br />
monitor with speakers, a keyboard with trackpad, two USB ports, and a large enough<br />
battery for roughly 5 hours of use. The smart phone acts as a motherboard with "good<br />
enough" performance. The advantage over a separate laptop or desktop computer is that<br />
you have one computing device so you don't need to transfer files between your phone<br />
and your desk/laptop.<br />
Unfortunately for Motorola, Lapdock was not successful (probably because of its<br />
US$500 list price) and Motorola discontinued it and sold remaining stock at deep<br />
discounts, with many units selling for US$50-100. This makes it a very attractive way to<br />
add a modest size HDMI screen to RasPi, with a keyboard/trackpad and rechargeable<br />
battery power thrown in for free.<br />
Lapdock has two connectors that plug into an Atrix phone: a Micro HDMI D plug for<br />
carrying video and sound, and a Micro USB plug for charging the phone and connecting<br />
to the Lapdock's internal USB hub, which talks to the Lapdock keyboard, trackpad, and<br />
two USB ports. With suitable cables and adapters, these two plugs can be connected to<br />
RasPi's full-size HDMI connector and one of RasPi's full-size USB A ports.<br />
The RasPi forum has a long thread on Lapdock with many useful suggestions, photos,<br />
and links: I made a Raspberry PI Laptop (http://www.raspberrypi.<strong>org</strong>/phpBB3/<br />
viewtopic.php?t=6747) . There's also a good 'blog entry at element14 with photos and<br />
suggestions of where to get cables and adapters: Raspberry Pi Laptop<br />
(http://www.element14.com/community/groups/raspberry-pi/blog/2012/09/08/raspberrypi-laptop)<br />
.<br />
The hardest part about connecting Lapdock is getting the cables and adapters. Most<br />
HDMI and USB cables are designed to plug into jacks, whereas the Lapdock has plugs so<br />
the cables/adapters must have Micro HDMI and Micro USB female connections. These<br />
are unusual cables and adapters, so check the links.
