I've been having a problem that has stumped me for months. I have a GTX 550TI graphics card and an Intel i5 2500k processor with Intel HD graphics 3000 running on a Gigabyte z68xp-ud3 board. The OS is windows 8.1. Before the incident occurred I had the only monitor connected to the graphics card via DVI. Both the dedicated and integrated graphics were enabled at the same time. I never had any problems and was able to play bluray movies just fine.
A few months ago I went to watch a movie and got an HDCP error which prevented the movie from playing. It hasn't been working since. I used Cyberlink's bluray adviser to try and determine what the problem was. It told me that there were actually two problems: 1.with my graphics driver and 2. that my display was not HDCP compatible. I think the HDCP problem is just a result of the graphics driver problem. I suspect this because the Nvidia control panel tells me that everything (graphics card, connection and monitor) is HDCP compatible and running fine.
What caught my attention in this report was that the graphics card was listed as the GTX 550 TI and the driver is 9.18.13.3165 (the Intel HD graphics driver number, not the 331.65 it should be for the gtx card). What I suspect is happening is that the movie software (Cyberlink PowerDVD) is doing its HDCP setup via the Intel graphics rather than the gtx card because of some driver confliction. So the HDCP setup signal is going from the Intel graphics through the card, to the cable and out to the monitor. The fact that the card is in the middle and it's not a direct connection from the Intel graphics to the monitor is where I think the HDCP problem is occurring.
I tried some typical things like doing a system restore to remove an Intel HD Graphic driver update that went through just before the problem occurred, disabling the integrated graphics in BIOS, uninstalling the Intel HD graphics driver from he system, updating the Nvidia graphics driver and restarting. Now the only graphics device showing up in device manager is the GTX card. However, I'm still having the same issue as before. The driver is still listed as the Intel Graphics driver in the Cyberlink Adviser and the HDCP error is still present. The Nvidia control panel continues to say that the connection from the GTX card to the display is HDCP compatible and good to go.
As a last ditch effort I tried ArcSoft's Total Media Theater just to make sure the problem wasn't with PowerDVD. No luck.
The only remaining option I can think of is to do a complete reinstall of the OS, which I REALLY don't want to do if possible. Sorry for the long explanation. Any help, suggestions or insight would be greatly appreciated.
