It would be unfair not to treat the Shuttle DS67U as a media player system. The box has two digital audio/video ports and supports two independent screens: 1) DisplayPort 1.2 supports 4096x2304 @ 60Hz and 2) HDMI 1.4 supports 4096x2304 @ 24Hz. Both outputs support Ultra HD / 4K resolution, Quick Sync Video and Clear Video HD technology.

For our Audio/Video tests we used the following setup:

TV: Panasonic 55CMX710E (4K +3D capable) with the latest firmware installed
A/V Receiver: Yamaha RX-V775 (7.2 capable) with the latest firmware installed
Wifi Router: TP-Link VR200 (802ac,b,g,n) with the latest firmware installed

We used several audio/video files from KODI Wiki. We also used the latest K Lite Codec pack and the Kodi platform.

According to its specs, the Intel HD 510 supports full H264, H265 8/10 bit, VP8/9, VC-1, AVC hardware decoding and HD video plus multi-channel digital audio via a single cable. With the Shuttle DS67U connected to our A/V receiver through an HDMI cable, we are ready to run some tests.

Note that in order to get automatically proper display scaling, we had to set the resolution to 3840x2160x23p. The 4096x2160x23p produced wrong scaling and we had to drop the horizontal scale to 50% under the Intel display properties.

Under Windows 10, it looks like the only 3D capable resolution was the 1920x1080p. The device locked at 23.975 fps with any video playback software we tried.

In order to get HD Audio you need to make some settings first. At the Media Player Classic (part of the K Lite Codec) you need to set the external filters . In KODI, you'll have to set audio to WASAPI HDMI of the TV Display and at 7.1. At the same time, you'll have to enable all the corresponding modes of your A/V Receiver.

As you see above, the audio compatibility was perfect. With KODI we easily got HD-Audio pass through along with a perfect audio playback; with the Media Player Classic you only get PCM 2.0 with AAC/LPCM formats. So using KODI is highly recommended.

Video Bitrate Tests

For this test we used a test file available at this page. The player was tested with up to 400Mbps files using all the possible sources:

Based on the Intel HD 510 graphics engine, the Shuttle DS67U maxed up to 250Mbit H.264 files. What you will not get is support for 10bit H265 files, as we experienced an unstable video playback. So you'd better connect the device through LAN (1Gbit) or even Wifi, as long as your system supports the 802.11ac mode (5GHz). Generally, the results here are good.

4K Tests x264 (AVC)

The Shuttle DS67U gave an almost perfect H264 video playback.

4K Tests x265 (HEVC - 8 Bit)

The player also showed a great compatibility with the H265 videos we tried, and had no problems with all the 8bit files. However, due to a limitation of the Intel HD 510 engine, the DS67U cannot playback 10bit or 4K VP9 videos properly.

We also tried to get 3D playback using both the Media player classic and KODI, but we encountered many problems...
