A user is trying to play a DVD on a projector. The user can hear the audio; however, the projector is showing an error message that states: HDMI Blocked due to Copy Protection Which of the following is the MOST likely cause of the error?
A.
The HDMI cannot carry the signal from the DVD to the projector.
B.
The user needs to switch from HDMI to a cable standard such as DisplayPort.
C.
The projector does not support the necessary HDCP protocol.
D.
The user needs to enable cony-protected sources in the projector's settings.

Protected content. If you encounter an error that indicates unauthorized content or an HDCP error: • DVI, HDMI, DisplayPort, and Thunderbolt all provide support for the Digital Rights Management (DRM) mechanism High-bandwidth Digital Content Protection (HDCP). HDCP allows a content source (such as a Blu-ray disc) to disable itself if the display adapter and monitor and/or speaker system do not support HDCP and fail to authenticate themselves with the playback source. There have been various iterations of HDCP (at time of writing the current version is 2.2) and backward-compatibility can be problematic as authentication may fail between devices that support different versions of the standard.
Displaying devices must support HDCP to stream videos. It either supports it or not. You can't enable it. Therefore it must be C.
The answer is D, the question does state the word copy, The user needs to enable copy-protected sources in the projector's settings. So the answer is D, is nothing do with C HDCP High-bandwidth digital content protection. The question is asking copy protection, Although Answer D has spelling mistake, it is not cony, it should be copy, I have looked this up in another sources, the answer is D
Sorry I was wrong, My tutor for the course gave this answer, Answer: C
Explanation:
Protected content. If you encounter an error that indicates unauthorized content or an HDCP error: DVI, HDMI, DisplayPort, and Thunderbolt all provide support for the Digital Rights Management (DRM) mechanism High-bandwidth Digital Content Protection (HDCP).
HDCP allows a content source (such as a Blu-ray disc) to disable itself if the display adapter and monitor and/or speaker system do not support HDCP and fail to authenticate themselves with the playback source. There have been various iterations of HDCP (at time of writing the current version is 2.2) and backward-compatibility can be problematic as authentication may fail between devices that support different versions of the standard. Displaying devices must support HDCP to stream videos. It either supports it or not. You can't enable it.
This is a very vague question, being a teacher that uses projectors often I have looked at the setting in our projector and it does not even support HDCP. So the answer for my projector would be C. The question gives no clue as to whether the projector supports DRM, so depending on that it could be either C or D.
The answer is D, the question does state the word copy, The user needs to enable copy-protected sources in the projector's settings. So the answer is D, is nothing do with C HDCP High-bandwidth digital content protection. The question is asking copy protection, Although Answer D has spelling mistake, it is not cony, it should be copy.

I agree. I feel that these are one of those iffy questions that Comptia likes to pull where which one would you need to do first here. For the sake of the exam, i would do C first. But let's say it was compatible, then D would be the answer.
HDCP (High-bandwidth Digital Content Protection) is a form of digital copy protection to prevent copying of digital audio and video content as it travels across connections like HDMI. If the projector does not support HDCP, it will block the content, resulting in the error message.
You are trying to play a video on a projector you can hear the audio but the projector shows an error message that states HDMI blocked due to copy protection Which of the following is the most likely cause
In this case, the error message suggests that the projector is unable to decode the HDCP-encrypted signal from the DVD due to its lack of support for the necessary HDCP protocol. As a result, the projector blocks the HDMI connection, preventing the video signal from being displayed
Answer: D
*Spelling error in answer. "cony-protection" should be "copy protection".
Reasoning:
The question states the user is already utilizing an HDMI cable. Therefore, the only answer could be D. HDCP cannot be the source of the issue if they are already using HDMI (an HDCP-compliant cable). Our best remaining option is to check the settings of the device.
Correct answer is D. The user needs to enable cony-protected sources in the projectors settings. because the question say HDMI blocked due to copy protection so the user needs to enable copy protection. "Cony" is a typo error for COPY, thats what i think
Very confusing...My answer is C (The projector does not support the necessary HDCP (High-bandwidth Digital Content Protection) protocol.
I thought that enabling or disabling copy-protected sources is typically controlled by the source device (in this case, the DVD player), not the projector. In my humble opinion, the issue is more likely related to HDCP compatibility between the source and the display device.
Option D, which states that the user needs to enable copy-protected sources in the projector’s settings, is not the most likely cause of the error message “HDMI Blocked due to Copy Protection” when a user is trying to play a DVD on a projector. This option suggests that the projector has a setting that allows the user to enable or disable the display of copy-protected content. However, this is not a common feature on projectors, and it is unlikely that this would be the cause of the error message. The most likely cause of the error message is still that the projector does not support the necessary HDCP protocol (Option C).
The MOST likely cause of the error message "HDMI Blocked due to Copy Protection" is option C: The projector does not support the necessary HDCP protocol.
HDCP (High-bandwidth Digital Content Protection) is a protocol designed to protect digital content (such as DVDs) from being copied during transmission. If the projector does not support HDCP or if it's not enabled, it may block the HDMI signal from the DVD player due to copy protection concerns. This will result in the user being able to hear the audio but not see the video on the projector.
