One of the things that caught out when Nexus 4 was announced is the Slimport accessory that allows you to charge and output the screen of LG Nexus 4 to a bigger screen or monitor. This technology is made b Analogix and while it does not have the coolness of wirelessly streaming the content, it is much more suitable if you want to want a movie on a bigger screen.
Right now, only HDMI Slimport is available but very soon, a display port version will be made available as well. The Slimport accessory for Nexus 4 will be on sale for $30 – not cheap, yes but very useful.
