1 Samsung AllShare Cast Dongle - $30
Connect any compatible (Galaxy Note 2, Note 3, S3 and S4) Samsung smartphone to your TVs HDMI over wireless - mirrors the phones screen in 1280x720p.
Powered by USB so if your TV also has a spare USB port, you don't even need the AC adapter.
Not practical for gaming as there's a noticeable lag, but fine for viewing photos & movies.
1 Samsung Smartmedia dock - $60
Plug any MHL compliant Samsung device (suspect it uses a Samsung MHL "standard" rather than the _actual_ MHL standard, so again, Galaxy Note 2, Note 3, S3 and S4) and connect it to your TV in up to 1920x1080 @ 30Hz (1080i basically).
Has 3 USB ports and 3.5mm audio output so you can plug in a mouse, keyboard and USB stick.
Virtually zero lag so can be used for gaming as long as it's via an external controller.
Pickup of either from Wellington CBD or can post\courier. Both items come with all original cabling, packaging etc.
