This is the first player to use the Dolby Vision variant of the new Realtek SoC, namely the RTD1619DR. This is the strongest differentiator to the previous launched Dune Pro 4K II, which does not support Dolby Vision. This implementation goes further than just playing Dolby Vision content. The incorporated Dolby Vision VS10 engine is also able to convert HDR to SDR and vice versa. This is a major improvement compared to Realtek’s SDR/HDR conversion. The Z9X is also the only media player to support all major HDR format: HDR10 (static meta data), broadcast friendly HLG (Hybrid Log-Gamma) plus the dynamic formats HDR10+ and Dolby Vision. The Hardware: With the latest SoC comes an increase in power as well as its based upon an ARM Cortex A55 hexa-core CPU with 1.3 GHz which is coupled with 2GB of RAM. The Z9X offers only half the RAM compared to the Dune Pro 4K II, but there is no real speed difference. The I/O is as follows: On the back of the device: Wifi-antennas Gigabit ethernet HDMI 2.0 output HDMI 2.0 input Optical S/PDIF A/V out (analog output) RS232 On the right side: External SATA connection 2x USB 3.0 On the left side; 2x USB 2.0 The package and what’s inside: The case: The case of the Z9X has the same footprint as the Dune Pro 4K II, which can be seen in the pictures below. Due to the lack of chamfered edges around the top the case looks just a tiny bit less premium than the Dune. Furthermore, the WiFi antennas can’t be detached. If you want all that from a Zidoo device you have plenty of options which offer different sizes, detachable WiFi antennas or internal HDD space. Having said that, the case is also made from metal and generally has a premium and sturdy feel. The front panel has just the right size to display the elapsed or remaining time during playback without being distracted. There are also indicators for the resolution like 4K and network connectivity, but these are too small to be visible for a normal viewing distance. Its brightness can be adjusted or it can be disabled altogether.
