I have a 2021 14" MacBook Pro running macOS 12.4 (21F79) that won't display streaming video in Safari when connected (Thunderbolt) to a LG UltraFine 5K display. It does the classic thing of playing audio but blacking out the video. If I use another browser, basically anything non-WebKit, it works perfectly well. Thunderbolt is the only connection to this particular LG display and using HDMI with my TV doesn't trigger the issue. Any hints as to how I can debug this issue so I can file a bug report or something?

Which Macs, both desktop and portable, support HDCP on their native displays? The web is awash with information on connected displays, and which support it, don't support it, and stories of people who weren't warned that theirs don't support it, paid $15 for a movie, and are now screwed. But for internal displays, I can find nothing. Apple's own Technical Specifications do not list HDCP support. Everymac.com has nothing. I was once able to play an HD iTunes movie on my Late 2008 MacBook Pro, but had to take a leap of faith that it supported HDCP. A StackOverflow answer indicates even a motivated developer couldn't make an app that determines whether a given Mac has HDCP support for its built-in display. It seems the only way - not exaggerating here - is to buy some protected content from iTunes and hope it works.

My setup is as follows: - MacBook Pro (13-inch, 2017, Four Thunderbolt 3 Ports) running macOS Catalina - Dell U2720Q monitor Monitor is connected to MacBook Pro using CableMatters USB-C to DisplayPort Cable (www.cablematters.com) I am running into HDCP error when playing movies on Amazon Prime Video (https://www.primevideo.com) . Screenshot below: I am getting same error when I use Belkin HDMI to HDMI cable (instead of above mentioned one). Is my system/os outdated or there is something else? Please help. Additional info: - Monitor that I am using, Dell U2720Q supports HDCP (DP 1.4 - HDCP 1.4/HDCP 2.2 and HDMI 2.0 -HDCP 1.4/HDCP 2.2) I have encountered above mentioned issue on latest versions of Google Chrome and Microsoft Edge browsers

I have a (non-Retina) MacBook Pro (mid-2012) and I have just purchased an Asus VN248H-P external monitor with HDMI input, connected to the MacBook Pro with a Monoprice Mini-DisplayPort to HDMI cable . This is not a television set; it is a peripheral computer monitor. For the first time, I tried to play a movie purchased and downloaded from iTunes on the external monitor, and I got an error message in iTunes saying that this is not supported because the Mac cannot verify HDCP support for my configuration. (This refers to the High-bandwidth Digital Content Protection encryption scheme ). > The selected movie won't play on one of your connected displays. > > This movie can be played only on displays that support HDCP (High-bandwidth Digital Content Protection). > > Try moving the iTunes window to a different display. Make sure the entire window is on the supported display. iTunes will only let me play the movie on the built-in screen on my (non-Retina) MacBook Pro, which is smaller and lower-resolution. Is my Monoprice cable incompatible, and do I need to replace it with a different cable or adapter? Is there such a thing as a cable or adapter that works with HDCP and will enable this? Or is playing HDCP-encrypted content simply not possible on my configuration? Please don't give me an answer that involves using software to break the HDCP encryption or to transcode to a different video format; I'd like to know if there is a hardware solution for full compatibility so that I don't lose any video resolution by transcoding.

[High-bandwidth Digital Content Protection](https://en.wikipedia.org/wiki/High-bandwidth_Digital_Content_Protection) (HDCP) was released in the mid-2000s, contemporaneous with the Apple Cinema Display line of external monitors: - 23", 30" Apple Cinema Display - 24", 27" Apple LED Cinema Display - Apple Thunderbolt Display Did any of the above monitors support HDCP? Can a connected macOS system display be queried to determine if it supports HDCP? This is relevant as many of the adapters needed to connect these monitors to a modern USB-C / Thunderbolt Mac have "HDCP on" and "HDCP off" versions of the same adapter. Which should be used? How can you determine if an Apple external monitor supports HDCP?

If I attempt to play movies on the TV app or Disney+ through the browser I am getting the following error: This is with a newish LG 5K monitor connected to a 2018 MacMini via Thunderbolt. Interestingly Disney+ works fine if I reboot into Windows via Bootcamp which tends to indicate the hardware is OK.

After getting the iPhone 5S, I have been having problems with the AppleTV connection. Sometimes it just drops as soon as I start Airplay mode from the iPhone, and most of the other times some error appears about HDCP. I never had these problems with the iPhone 4S and tried updating the AppleTV and that has fixed nothing. How do I fix this issue ?

When i connected mac to external five panasonic led display with Extron DA6 distribution amplifier, only four are connected but last dispaly flicker and then stop showing content. I'm running on macos sierra version 10.12.1 processor 2 ghz, i7 processor, graphic intel iris pro 1536 mb. How can I tell if this is a HDCP or edid issue?

I've found a few questions on here that are several years old and ask about general HDCP support. However, with the oncoming 4k revolution a new version of the specification, HDCP 2.2, has been introduced specifically to lock down 4k content. For instance, in order to stream Netflix at UHD quality, your display (and cables/connections) must support HDCP 2.2. From the [Netflix UHD Help Page](https://help.netflix.com/en/node/13444) : > Please note that both the HDMI cable and the HDMI port on your TV must be HDCP 2.2 certified. I'm having a hard time finding any hard facts on this. Mostly I'm curious about my current device, a 15" Mid 2014 MBP with an Nvidia GT 750M and retina display.

I have a dual-link (2560x1440) DVI monitor connected to my computer (2015 retina MbP) through the [Apple Mini DisplayPort to Dual-Link DVI adapter](http://www.apple.com/shop/product/MB571LL/A/mini-displayport-to-dual-link-dvi-adapter) . It is reported as not HDCP-complient by iTunes and Netflix. Is this because the monitor doesn't support HDCP, or because the adapter doesn't pass the HDCP?

I occasionally receive the infamous HDCP error (as seen below). However, I don't have an external display connected. It happens on the MacBook's built in display. This happens MID VIEWING. It starts playing fine, then randomly I get this error. I can always restart it, but it's become a pain. Any ideas?

Here's my setup. I purchased a HD movie (my first ever!) from the iTunes Store onto my Mac mini. iTunes on this Mac mini is configured for Home Sharing. Now, when I launch the Videos app on the new iPad, it lists my Shared Library correctly together with the movie that I just downloaded. However, when I tap the Play button, the screen goes blank for a moment before displaying a "Cannot Open" error message. I am bedazzled by the fact that I can't play this very same movie on my HDTV which is connected to the Mac mini via Mini DisplayPort to HDMI cable (HDCP error, but that's another story for another question), I'm now totally flabbergasted that I can't even play this movie via a channel that Apple has been shouting about. I tried playing the movie on my MacBook Pro and it works correctly, therefore the file is not corrupted. I am also sure I can sync the entire movie (all 7GB of it) into my new iPad, and watch it from there, but why?
