HTPC Credentials - Display Outputs Capabilities

The Zotac ZBOX CI660 nano comes with two  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 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.

HD Audio Bitstreaming Yes

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 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. The list of supported modes seen by the system didn't include PAL (50 Hz), but, this was trivial to fix by adding a custom resolution in the Intel Graphics Command Center.

We tested out various display refresh rates ranging from 23.976 Hz to 59.94 Hz. 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

Zotac claims that the HDMI output port supports HDR, but, we were unable to get HDR working with our two test displays - the TCL 55P607 via a Denon AVR-X3400H, and a LG 34BK95U. The OS did present the HDR toggle button in both cases. However, activating it resulted in a complete loss of activity on the HDMI link. In the interest of full disclosure, Zotac did indicate that they managed to get HDMI 2.0 4Kp60 output with HDCP 2.2 active and HDR enabled using the LG 27UK600 and the Dell UP2718Q monitors.

The CyberLink Ultra HD Blu-ray Advisor tool does indicate that our setup (Zotac ZBOX CI660 nano + 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. It is just that HDR didn't work in practice in our particular setup.

    BAPCo's SYSmark 2018 is an application-based benchmark that has been developed by Intel engineers for Intel CPUs and does not truly reflect performance of any real world application by any other chip vendor. The fact that every other chip maker have all abandoned Bapco's boards tell you something. This is a known conflict of interest that degrades Anandtech's credibility by highlighting it. At least in the past the articles, these conflicts were pointed out regarding Bapco's shaky past.

    Anandtech's quality has been on a continuous downward slide, including increasing Intel/Nvidia bias, ever since Anand left. The site looks and sounds like it's written by children now - especially including comments the editorial staff post in comments sections and on twitter.

    Hey what about my Andrei

    While I would agree that the quality is not near as good as it was when Anand was around, I don't see any bias.

    Read literally anything written about a Killer NIC.

    Seems like this article only compares Intel systems to other Intel systems - so what's the problem? Other than, of course, this article does not agree with some personal bias of yours, therefore all of Anandtech is now not credible, etc. A little extreme reaction don't you think? But such is the way witht he extremism in EVERYTHING these days. Social media has destroyed any chance for critical thinking. Anandtech does an article that's positive towards Intel, OMG BIASED, They hate AMD. They write a different article that's positive towards an AMD product - OMG BIASED! Why the hate on Intel?

    Yup, using a benchmark by Bapco in which no chip company besides Intel seems to have confidence does leave a rather bad taste.
    nVidia, AMD and VIA all left the consortium back in 2011 and prior to that Bapco was found to have modified their benchmarks in a way that favored Intel CPU

    SYSmark 2018 is one of several tools we use in this article. It is certainly not the only tool we use, and it's not a tool we use in all situations (e.g. architecture deep dives). Meanwhile for SFF PCs in particular, its power measurement capabilities are pretty handy to have. Plus the only other systems we're comparing it to are all Intel-based anyhow.
  • MDD1963 - Thursday, April 18, 2019 - link

    If BAPCO SYSMark was developed by Intel engineers, this would seem more an issue if/when comparing Intel systems to AMD, and not really an issue when comparing all Intel systems...

    The Realtec NICs may be a blessing for use with Windows Server (Intel has a nasty habit of not providing drivers for many of their NICs). Having two will let you set up a team there (perhaps to use as a AD/DNS server) or use as a firewall/router (not that I'd use Windows Server for either).

    I've generally had good luck with Realtec with Windows Server and PFSense.
