There are a fair amount of Android TV boxes to choose from but if you want the perfect home theater you want a 4K Ultra HD set-top box (STB), like the HIMEDIA Q5 Pro, that supports Dolby Vision high-dynamic-range (HDR) technology!
The HIMEDIA Q5 Pro is powered by HiSilicon Hi3798C V200 64-bit ARM Processor (providing up to 15K DMIPS) which features four Cortex A53 cores and Mali-720 graphics processing unit supporting OpenGL ES 3.1/2.0, OpenVG1.1, EGL, and Imprex 2.0 PQ engine.
With the HIMEDIA Q5 Pro you get an aluminium casing, 2GB of DDR3 RAM, 8GB of eMMC5.0 high-speed flash storage, KODI pre-installed, USB 3.0 interface, 10-bit HEVC as well as VP9 video decoding and HDMI 2.0a which runs 4K (3840×2160 resolution) 10-bit color at 60 Hz refresh rate.
HDMI 2.0a means the connection transfer (18 Gbps) is even faster than regular HDMI 2.0 (10Gbps) so you get much better image quality.
As far as connectivity, the HIMEDIA Q5 Pro can connect via Dual Band Wireless AC WiFi, Gigabit Ethernet and Bluetooth 4.0.
You get in total three USB ports, two USB 2.0 ports and one USB 3.0 port, as well as SD card slot. The USB ports are located on both sides of the TV box, while the HDMI port is located on the back, next to the RCA jacks, external antenna and both coax optical and Toslink digital audio.
The user interface is easy to navigate with the included remote control and you get pre-installed apps (including KODI).
The overall performance of the HIMEDIA Q5 Pro is very good thanks to high speed read (around 750 Mb/s) and write, full 4K HDR output and built-in hardware decoder and Imprex 2.0 image processing engine that supports full 3D format and up to 10-bit color depth (around 1.07 billions colors), providing smooth and natural picture quality.
The operating speed of the HIMEDIA Q5 Pro reaches almost 15K DMIPS, plus the Q5 Pro features 7.1 HD audio and supports all HD-audio formats.
