If what you want from a media player is to stream movies to TV, you want a media player such as the PROBOX2 Air Plus  or the ProboX2 AVA that is highly optimized for video playback. The PROBOX2 Air Plus is an efficient way to stream large movie files to TV as it can handle all video formats and codecs.
The PROBOX2 Air Plus is very similar in size to the PROBOX2 Z media player but with upgraded specs that include Amlogic S912 system on a chip that is highly optimized for video playback so it supports media playback formats from 4K at 60 frames per second video to h.265 with 10 bit color and 8-bit color, as well as vp9 which is the future of ultra high definition video playback on the Internet.
With the PROBOX2 Air Plus Android 6.0 TV Box, you also get 3GB of DDR4 RAM, 32GB of flash storage and expandable adoptable storage as the box runs Android Marshmallow operating system. This means you can adopt an SD card as part of the system so you can store apps and system files.

You will need the fastest class microSD card that you can get, preferable a UHS-1 microSD card, so apps can run normally off of adoptable storage.
As far as design functionality, the PROBOX2 Air Plus has a small form factor so it's slim and super compact (weighs only 190 grams). The total dimensions are 10cm long, 11cm wide and 1.5cm thick.
As far as ports, you get a mixture of ports on the back and side of the unit. These include optical audio out, 1000 megabit Ethernet, a USB port and HDMI 2.0 that is capable of ultra high definition at 60 frames per second. The micro SD card slot and additional USB port are located on the side of the box.
As far as the software, the PROBOX2 Air Plus uses the PROBOX2 APEX UI Launcher which is made so it can be controlled with a toggle remote control. The APEX UI Launcher also features active port indicators, "USB storage device eject" feature and launcher swap (<>), called 1 click swap button that allows you to quickly swap between launchers you have installed.
Another feature worth mentioning that comes built-in with the PROBOX2 Air Plus is Bluetooth 4.0, which is great as it means you can connect a Bluetooth game controller to the PROBOX2 Air Plus and do online gaming.
