Disable HDCP to lower DPC Latency

[ALAK]

HI i want ask if we can disable HDCP on intel arc like another cards like amd and nividia to reduce latency Like this 


Content that requires HDCP will probably not work.Windows or driver updates will likely revert the configuration, as will reinstalling the display adapter.

Configure the following DWORD value below for your active display adapter then resart your computer. This should cause Nvidia to display This display does not support HDCP as configured in the Nvidia control panel in the View HDCP Status sub-menu, third party tools can also be used to validate HDCP is disabled.

The key 0000 in the registry reflects the path of the active display adapter, look for the value of HardwareInformation.AdapterString to help identify your display adapter and the appropriate key to create the DWORD in. (e.g. 0000, 0001, 0002)
Example
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0000]
"RMHdcpKeyglobZero"=dword:00000001

Restart your PC.

Hello ALAK

Thank you for posting on the Intel Communities.

Disabling HDCP is not something we have tested nor something we support, the technology was developed to protect digital content from illegal copying, as well disabling HDCP requires modifying the registry so you would need to do it at your own risk, however, as mentioned this has not been tested and it might cause other issues with the GPU.

Hello ALAK

As mentioned in our previous post HDCP is implemented to protect digital content from illegal copying, unfortunately, we can't provide support to disable it, you would need to do it by your own means and at your own risk.

Hello ALAK

I will check this with our team to see if there is any other information we can share, however, as mentioned this is not supported so we cannot commit to any outcome. Once I have an update I will let you know.

Hello ALAK

I checked this topic with our team, and we want to let you know that there is no option within Arc Control or the Intel® Graphics Command Center to disable HDCP nor can we provide instructions to modify the registry. As a workaround, something you can try would be to use a splitter or dongle that does not support HDCP and check if that works to disable it.

Hello ALAK

As advised in our previous post you can try using an adapter or dongle that does not support HDCP to try to disable it as a workaround, however, we cannot guarantee it will work. Since there are no further questions we will close this thread. Feel free to open a new topic if you have further questions.
