First impressions, settings, overview of features

The ZIDOO X9S has a good quality aluminum housing. Visually, it looks like a high-end device. Indeed ZIDOO attaches great importance to design and quality. The whole case looks very aesthetically.  X9S TV Box runs on Android 6.0, but the most important features are an HDMI In with PiP (Picture in Picture) and DVR – video recording function. As we said at the beginning of his heart is a new Realtek RTD1295 which offers the latest generation HEVC/VP9 4Kp60 video decoding technology with HDR10 capability to deliver wider color range and greater contrast for an enhanced viewing experience. On the front panel X9S has LED display, IR receiver with Power LED.

Below we include the ZIDOO X9S photos in combination with a matchbox and other small flagship TV Box from ZIDOO called ZIDOO X6 Pro, so it was easier to see the size of ZIDOO X9S Android TV Box.

Booting Android to the “home screen” takes about 00:32:01 seconds. As always ZIDOO launcher (ZIUI) is clear and nicely designed, allowing easy available in the most important features. Also, easy access to the status bar where you can find PIP function.

The device worked in the resolution of FHD 1920×1080 (1080p 60Hz) but you can also adjust the preferred resolution or set the auto switch. Everything worked stable and very quickly without delays, Netflix also works without problems. ZIDOO X9S support also DLNA, Miracast and AirPlay. We had no problem with Ethernet and WiFi connection to router and to Internet. In addition to the remote control I used a standard keyboard and mouse and Gamepad GameSir G3s ZIDOO X9S has a lot of settings HDMI and video playback (auto switching to 1080p 24Hz and other). Although the specification is 16GB of storage on the device it is available about 9GB of internal storage. Not constitute a problem because device has a SATA port, so you can connect an external drive. Remote control from X9S looks great and works great, has two buttons to which you can hook up your preferred applications (Shortcut Key-setting). TV Box can also be controlled (such as previous models) dedicated application on smartphona – Box RC. Below a some screenshots.

As mentioned earlier TV Box has many features important to also include – support OpenWRT with NAS and HDMI IN. With enabled OpenWRT service X9S TV Box, can serve as a router and a NAS with multiple services, such as Samba, FTP, Bittorrent Client and others. You can easily find ZIDOO (with NAS servicec) on the LAN. You can mount the disk partition on your PC, the smartphone without a problem reading a network share. Copying file from the NAS to the PC is fast. Below screenshots.

Another strong advantage X9S TV Box is a HDMI IN port through which you can receive live images from the DVB-T Digital TV tuner. The device easily displays an image via PIP, records and allows live streaming via broadcasting. To play a video broadcast on the LAN on your smartphone well suited to the application GoodPlayer for Android. PIP window can be positioned anywhere on the main screen. Below screenshots of the available settings.

ZIDOO X9S like other model from ZIDOO has ZDMC app based on Kodi 16.1 Jarvis (the exact version ZDMC 16.4-8). On TV Box can play popular games available on the Play Store. Just connect the gamepad. This combination really makes it ideal for entertainment. Real Racing 3 and Beach Buggy Racing work great.


Operating system and components

The ZIDOO X9S runs on the Android 6.0 Marshmallow, namely version 6.0.1 and the Linux Kernel version 4.1.17. TV Box comes with firmware build number v1.1.20 It was enough to connect the TV Box to the Internet, and we have access to updates via OTA (Big plus!). We updated device via OTA (zip file) to latest firmware version build number v.1.2.7

TV Box is equipped with SoC Realtek RTD1295 ARM Cortex-A53 Quad-Core processor and GPU ARM Mali-T820MP3. On the following screens you can see exactly the components used and their specification (Information taken from the CPU-Z app). CPU-Z app does not recognize too well RTD1295. The device is detected as ZIDOO_X9S (rtk_kylin32) and board kylin. Below some screenchots.

After using the DRM info (app) we know that ZIDOO X9S TV Box doesn’t support Google Widevine Moudlar DRM, Marlin DRM and Verimatrix VCAS, but support Microsoft Playready DRM.

Performance tests and benchmarks

For testing I use the AnTuTu Video Tester 3.0 app and AnTuTu Benchmark 6.1.4. The result 894.

In addition ZDMC based on Kodi, ZIDOO prepared a great app called Home Theater. This is a very good movie player. Scans media and search movies, search movie posters of films. Home Theater app has also previously described features. Unfortunately failed to open through the app the files VP9 4K .webmv (from youtube). Other files and 4K worked well. Below some screenshots.

Perhaps ZDMC version of the firmware v1.2.7 was not optimized or something has been changed because not all video in 4K to work smoothly. In addition, other files with the resolution of 480p,720p and 1080p (24fps30fps, 60fps) with various codecs video such as H.264,H.265, MPEG2, MPEG4, RMVB plays without problem, AVI, MKV, MP4 (typical formats in which it holds the majority of movies), ISO and also videos was played fine. Audio – DTS and AC3. Dolby Digital 5.1 passthrough worked fine via HDMI. TV Box Also copes well with playing the video on YouTube – videos plays in 1080p. Also, we tried to play VP9 4K video and runs smoothly without problems.
