U2311H HDCP compatibility

Question

I am trying unsuccessfully to play a Blu-ray dvd and Cyberlink BD Advisor reports everything OK but fails the monitor - ' digital (without HDCP)'. My Nvidia GeForce 8400 GS card also reports 'this display does not support HDCP'. It is connected through DVI-D cable and works perfectly otherwise. In the spec for the monitor indicates compatibility so what could be wrong?

Hi. Tried the Dual Link cable and still get 'not HDCP compliant'. Spec for geForce8400GS says it is HDCP compliant but has a Single Link DVI ! :emotion-42:

warning: HDCP compliant is not the same as HDCP capable!

* Press the monitor menu button to open the OSD (On Screen Display). The bottom of the screen should state: Resolution 1920 x 1080 @ 60Hz
* Is there another DVI port on the 8400 to test?
* Is there another DVI cable to test?

Thanks for your response. OSD shows resolution 1920x1080@60Hz. Only one DVI port on graphics card. Tried new DVI-D cable, tho it's the same type with two bunches of 9 pins and one to the side. No joy. Just about to post this when I spotted forgotten PS3 beneath my printer. They're supposed to play BD discs. Connect thro an HDMI-DVI adapter and... Success! So monitor IS HDCP compliant and I am left with the cable or the graphics card. A bit naughty of it to report the monitor if it is itself at fault. Could it really br the cable?

'two bunches of 9 pins and one to the side' = DVI-D Single Link You need a DVI-D Dual Link cable seen on left -

Is a Dual Link cable required for HDCP compliance or is it required to display BD disc stream.

DELL-Chris M · Answer

Not necessarily. The HDCP specification is complicated, but the result is simple:  If you have an HDCP-enabled source component, every active device that connects to that source must also be HDCP-enabled. It would be an inexpensive thing to try before replacing the video card.

Thanks for your help. I have ordered a Dual Link cable but I strongly suspect the card is only Single Link. You can't tell from the socket - it has a full set of pins. I'll post here when I've tried the cable..
