HDCP disable

Jump to solution

Any tips on how to get HDCP working on my system?  When I look at my settings in AMD Radeon Pro under my monitor it shows "Current HDCP Status: Disabled".  I've tried different driver sets including 18.Q3, 18.Q3.1, and even the Adrenalin Edition Beta for Windows October 2018 Update drivers.  I'm using the DP port to connect directly to the monitor.  I know my DP cable and monitor support HDCP because when I boot my PC using the Intel HD graphics, everything works fine.  Any suggestions?  Below are my PC specs.

Dell OptiPlex 7040

i7-6700

16GB RAM

AMD Radeon Pro WX 3100

Windows 10 1809 (17763.1)

Looks like a regression on AMD driver side. This issue is being investigated.

Not sure if the latest AMD Professional Driver is completely compatible with Windows version 1809 (RS5).

This is the Release Notes for the latest AMD Driver for the WX3100: Radeon Pro Software for Enterprise 18.Q3.1 Release Notes | AMD

EDIT: The above image could be a old image prior to the October 2018 update and hasn't yet been updated.

60hz.JPGI have the same situation. HDCP Status disabled.....what does this mean in terms of video playback.

I have a 4K HDCP2.2 monitor using HDMI cable.

I can stream 4K content (NETFLIX) using EDGE and as I presume that is HDCP protected this function is being ignored.

As a test I loaded 17.7.1 driver and that showed HDCP status enabled.

However anything 18.3.1 onwards is HDCP status disabled.

Can anyone explain this please.

on 18.8.1 at the moment (copy all on specs show)

Horizontal Timing Total - 4400

Horizontal Timing Display - 3840

Horizontal Timing Front Porch - 176

Horizontal Timing Sync Width - 88

Vertical Timing Total - 2250

Vertical Timing Display - 2160

Vertical Timing Front Porch - 8

Vertical Timing Sync Width - 10

Horizontal Timing Polarity - Positive

Vertical Timing Polarity - Positive

Interlaced/Progressive - Progressive

G.Pixel Clock (KHz) - 594000

G.Refresh Rate (Hz) - 60

Current HDCP Status - Disabled

Current Link Settings - Not Available

By the way does the AMD driver support HDMI Ultra Deep Colour?

What is the preferred choice  for colour depth RGB or YCbCr

I've tried the Beta drivers for the October 2018 update (Radeon Pro Software Adrenalin Edition Beta for Windows October 2018 Update Release Notes | AMD) and the problem is still there.  When trying to watch a movie on the Vudu app, I get the error "The display does not support HDCP".  Hopefully this will get address in the next release.

If you are using Display Port, you will need a v1.4 DP Monitor, display port v1.2 does not support HDCP 2.2

Not many Display Port v1.4 spec monitors as yet and they cost a fortune.

Is that recent change?  When I roll the driver back to 18.Q3, the issue with Vudu goes away,  AMD Settings still shows HDCP disabled with 18.Q3.  When I try the more recent drivers (18.Q3.1) Vudu throws the error.  I've also tried connecting my monitor via HDMI and I still get the Vudu error on the more recent drivers.

Does Vudu have any software or APP that you use in Windows to view VUDU Content?

The reason I am asking I just found out from another thread the Netflix Windows APP as a bug that prevents it from viewing 4k on a monitor and the Netflix was working on a fix.

I was wondering if maybe Vudu may have something similar and may not be completely compatible with the latest Windows Version 1809.

SOLVED! Vudu support just got back to me and suggested that the software for the monitor was not HDCP compliant. While that is a bit vague my mind immediately jumped to drivers. Lo and behold both monitors had generic UPnP drivers signed by Teamviewer! I selected the Update Driver option in Device Manager and navigated to the appropriate drivers I downloaded from BenQ's website for both monitors and without even needing a restart I was able to watch my movies in HD! Thanks Nick G from Vudu support!

Figured I would post here publicly in case anyone else were to be searching for a solution to a similar problem someday.
