Please don't throw the word "FUD" around, especially when you didn't understand the comment.
GGP did mean HDCP 2.x (DRM to encrypt the signal between display and device) which is often not supported by commercial displays. Unless devices detect a compatible, DRM-protected display, devices will refuse to play UHD content made by the movie industry.
- rsync 5y agoThis is true, of course, but modern commercial displays typically do have modern hdmi and hdcp specs so it shouldn’t be an issue. Even 12 year old NEC p-series (used at airports, usually) have hdcp.
- giantrobot 5y agoTo stream 4K from commercial services you need HDCP 2.2 or later. This was only introduced in 2013 so a 12 year old TV will not have full HDCP 2.2 support. It might have 2.0 (released in 2008) but that won't enable 4K streaming from a commercial service. All streaming services require HDCP 2.2 support throughout the device chain. Because commercial displays aren't intended to use on-device streaming services or be used in consumer environments they often lack HDCP 2.2 support. While they might support HCDP 1.4 or 2.0, that will only support FHD content either streaming or disc-based. It's fairly difficult to find specs on commercial displays about their HDCP support level.
