I'm not too sure about this. I use AppleTV with our industrial display playing back HDR content without any issues. Here's a 4K video playing via AppleTV on a 16ft x 9ft indoor display at our facility: https://imgur.com/a/3O58O8T https://imgur.com/a/3O58O8T

Are you sure you are actually playing HDR content? The AppleTV will output 1080 SDR content or even below that too… Do these displays support HDCP? Are they locked at 60 or 30hz refresh rates? There is a reason why computer monitors make really poor display devices for multimedia content.

  Majority of our customers use our displays for Digital Signage so I would assume we would've heard of their issues if they couldn't playback their 4k or 8k content. Some of them play this content back on videowalls, as large as 14x8 configuration, without any issues. I will double-check with our firmware designer to be sure. From what I know, I believe HDCP is supported by all versions of HDMI. Older TVs, specifically the ones without HDMI input (i.e. component, vga, rca or coax input), wouldn't be able to support this. Majority of our current controllers are compliant with HDMI2.0 spec. Someone else here asked about HDMI2.1a and I'm going to get an answer on that from our firmware designer this weekend.

    HDCP is separate from HDMI. You can be spec compliant with HDMI at any version and not support HDCP. That said I would be surprised that a display controller in common use would not support HDCP. 4K or 8K content sure, but what about HDR? Especially at sizes less than 40” that’s more important than res for viewing content.

    Signage displays do not need to display protected content, they do not need to support standards like DolbyVision and they do not need to support three-two pull-down to display cinematic content without judder. HDCP isn’t supported on all versions of HDMI it’s not part of the spec it is a standard that is supported on top of w/e display interface you are using.

      You're right, firmware designer just confirmed that Digital Signage applications don't use HDCP (he actually said "prefer not to use") but he does believe that our controllers using MediaTek SoCs support HDCP and a separate firmware build could be made for this use case...or maybe even a toggle DIP switch could serve this purpose on the controller PCB.

        The controllers may support it but you will be the one will have to buy a license and the keys from DCP. Overall I don’t think you realize just how difficult your venture might be. Signage displays will make really bad televisions. They are optimized for long term operations over color accuracy and gamut, they usually operate at fixed refresh rates, and their latency is usually pretty terrible. I don’t think you realize just how small the market for what you are looking to build in the first place is and how difficult it would be to make anything that is remotely useable as a display for movies and video games. Those who want a dumb display can already buy one of those 50-65” enterprise displays for meeting rooms however they make pisspoor TVs and having to pay 3-5 times the price of even a high end TV makes them pretty pointless for even the user base that might want that. The large format gaming monitors are an option but recently they are adding “SmartTV” features to them because that’s what most consumers seem to want. Both LG and Samsung are making 30-40” gaming monitors with apps these days like Netflix because they seem to be quite popular with students and flatsharers.

        I understand what you're saying. We work directly with Samsung. While HDCP may be a challenging idea due to licensing issues, obtaining LCD panels with faster response times and higher refresh rates isn’t a problem for us. In fact, these consumer-grade panels are much more readily available than actual industrial panels. If we encase these 32-40" panels in an industrial metal casing, we can create a product that is more desirable than similar models housed in plastic with SmartOS, and more affordable than an Apple XDR.
