HTPC Credentials - Display Outputs Capabilities

The XPC slim DH370 comes with 3 display outputs, and their characteristics are summarized in the table below. From a HTPC use-case perspective, the entries of interest include the ability to support UHD (3840 x 2160) or higher resolutions, along with HDR and HDCP 2.2. The latter enables the display output to be used for viewing protected content such as 4K Netflix streams and play back UltraHD Blu-rays.

Shuttle XPC slim DH370 Display Outputs
  HDMI DisplayPort 1 DisplayPort 2
Version 2.0a 1.2
Max. Video Output 3840x2160 @ 60Hz 4096x2160 @ 60Hz
HDCP Yes (2.2)
HDR Yes
HD Audio Bitstreaming Yes

The system allows all three display outputs to be simultaneously active at the maximum rated resolutions. To maintain uniformity, we tested all three outputs driving a 3840 x 2160 display at 59.94 Hz in 'extension' mode.

The system has no trouble running three 4Kp60 displays and doing casual browsing or animation displays on all three at the same time. We will be analyzing more interesting use-cases in a later section.

Supporting the display of high-resolution protected video content is a requirement for even a casual HTPC user. In addition, HTPC enthusiasts also want their systems to support refresh rates that either match or be an integral multiple of the frame rate of the video being displayed. Most displays / AVRs are able to transmit the supported refresh rates to the PC using the EDID metadata. In some cases, the desired refresh rate might be missing in the list of supported modes.

Custom Resolutions

Our evaluation of the Shuttle XPC slim DH370 as a HTPC was done using the native HDMI output connected to a TCL 55P607 4K HDR TV via a Denon AVR-X3400H AV receiver. We also performed additional testing after connecting one of the DisplayPort outputs to a LG 34WK95U 5K monitor.

Various display refresh rates ranging from 23.976 Hz to 59.94 Hz were tested. Of particular interest is the 23.976 Hz (23p) setting, which Intel used to have trouble with in the pre-Broadwell days.

The gallery below presents screenshots from the other refresh rates that were tested.

The system has no trouble maintaining a fairly accurate refresh rate throughout the duration of the video playback.

High Dynamic Range (HDR) Support

The ability of the system to support HDR output is brought out in the first line of the madVR OSD in the above pictures. The display / desktop was configured to be in HDR mode prior to the gathering of the above screenshots.

The ideal desktop experience needs a YCbCr 4:4:4 or RGB output in order to avoid chroma subsampling artifacts on text content in HDR mode. The Shuttle XPC slim DH370 has no issues with this aspect.

The CyberLink Ultra HD Blu-ray Advisor tool confirms that our setup (Shuttle XPC slim DH370 + Denon AVR-X3400H + TCL 55P607) supports HDCP 2.2 along with HDR. The PC also satisfies other requirements (such as SGX and appropriate Management Engine firmware) to enable playback of Ultra HD Blu-rays.

In fact, we were able to activate UHD Blu-ray playback on our standard HTPC setup, as well as the LG HDR 5K monitor driven using one of the DisplayPort outputs.

    Don't get me wrong, I would like that too. SilentPCReview.com needs to be revived perhaps. They, and their community, were the best. People lost interest I guess once storage drives, power supplies, retail computers, even GPUs improved noise by a lot. Plus other reviewers started paying attention to noise partly through their work. But with mini PCs and HTPCs maybe there is renewed thirst for noise analysis.

    The issue may be - how does Ganesh prevent outside factors and just the changing ambient noise level from influencing noise measurements? He would need some type of anechoic chamber and probably some audio equipment. Read this to see what goes into it, for removing outside influence and actually having a low enough ambient noise level for meaningful measurements - http://www.silentpcreview.com/anechoic_chamber_SPC...

    Then there are logistics issues. Will Anandtech pay for or provide what may be needed? Does he do review work at his house/apartment? Is there an Anandtech central office? Do other Anandtech reviewers mostly live in the same area? Can someone rent an anechoic chamber? Keep in mind SPCR was mostly one guy on a mission, while Anandtech and Ganesh have plenty of other concerns.

    Is there a spot in the middle where noise measurements are "good enough"? Any ideas? I do see noise measurements at other review sites sometimes, but I don't know if they are good enough for comparing among different product reviews that took place at different times and possibly at different places.

    This query comes 3 years later, so I know that the odds on a response are not good, but WHICH existing Shuttle model is going to have more than adequate HTPC chops and features, as well as the desired quietness, heat dissipation, and reliability characteristics ? (Regardless of price, even.) I say existing model because I like Shuttle, and I don't care to build something from scratch out of disparate parts that may be available. The SH67H3 cube that still serves as my desktop computer would certainly fill the bill, and is plenty quiet even a few inches away on my desk, but of course it is several times the size and would require space I don't have in either of my video stacks.

    Another design factor that struck me as being perhaps dubious in these more compact, digital kiosk or signage oriented models has been the move to outboard power bricks, rather than an integrated PSU. But perhaps that is unavoidable, given the compact size.

    How about 3D BD ISO playback?
    Does it use LSPCon for HDMI?
  • timecop1818 - Monday, May 6, 2019 - link

    Yes, it uses MegaChips MCDP2850 to convert DisplayPort to HDMI 2.0. You can see it on the motherboard photo in the QuickStart manual. What about 3D BD ISO playback? Why wouldn't that work?
  • ganeshts - Monday, May 6, 2019 - link

    3D is usually not supported if you have a LSPcon. I have reason to believe 3D is not supported over the HDMI 2.0a ports in the last two Intel platform generations.

    With the advent of 4K and HDR, the industry has got much more convincing features to make people upgrade their equipment (compared to 3D). Effectively, 3D is dead from an industry viewpoint. YMMV.

    great example of a tech killed off by lack of content (i mean good content). too many movies were simply reprocessed without being produced from the ground up with the intent of 3d. the industry tried to charge a premuim for lackluster content with hardware implementations having support and quality issues. not to mention some big problems like focal blur guessing.

    i really hope vr doesnt go the route of 3d games and 3d movies. but yeah people dont seem to understand that the most important things are affordability and minimizing barriers to entry. also not having an industry clinging to ancient monitization practices helps.
  • Death666Angel - Monday, May 6, 2019 - link

    I think it is more about the technology itself. In order for stereoscopic 3D to work well, you need to have most of your field of vision filled by the content. That is easily done in a cinema, where the screen is huge and the ambient lights are darkened and everyone is fine with that. At home, most people I know have their setup with a small TV (37" to 50") and it is in a corner somewhere it makes sense but is out of the way (since the TV may be on a lot, but hardly watched focused most of the time). Only some die hard movie people (like myself) have a large TV (55"+, preferably 65"+) that is not too far away from the main sitting position (couch). But even then, it is a bit too small for 3D to work well and immerse myself in it and I can't really darken everything down as much as in the cinema. And I have never had comfortable 3D glasses. They always either hurt my sides or my nose.
    VR won't go away as 3D will, since it has a much larger impact in the professional world (engineering, architecture, medicine, art...), but home VR has an uphill battle to fight still.

    Honestly I'm kind of expecting 3D to come back again.

    They are now making fully transparent TVs.

    Layer the screens and you can have actual 3D (at least two layers of depth) without glasses.
  • Death666Angel - Tuesday, May 7, 2019 - link

    How would that work? You still need a way to block one eye from seeing the content the other eye sees. Doing it with a parallax barrier requires cost and doesn't work for more than one person without a lot of complications (which increase price, a lot). You also lose resolution compared to full 3D SBS and active shutter glasses.
    Or do you just mean 3D in a diorama way where you have discreet layers of content? That is not 3D.

    Thanks ganeshts.

    I know it's a dead format, but I would like to use it as long as my TV lasts.
    Hoping one day I can get a modern PC that has native HDMI ports (no LSPCon).

    Does anyone know of TB3->HDMI adapter/cable that does work?
