Re: XPS One 27, Windows Media Center 8, not playing HDCP?

Jump to solution

I cannot get any data from engineering concerning HDCP. What happens if you do this:
* Open the NVIDIA Control Panel
* Select Manage 3D Settings
* Under the Global Settings tab, select High-performance NVIDIA processor
* Click Apply- OK
* Close the NVIDIA Control Panel

Test the copy-protected channels.

Thank you for your suggestion, Chris.  Switching from the default Intel HD Graphics to NVIDIA High Performance Graphics had no effect.  Media Center responds the same: It will display the Copy-Protected channel for about three seconds then show the Display Driver error.  Media Center will do this to enforce DRM copy-protection if the computer's display use an internal DisplayPort for connecting its integral touchscreen display (the XPS One display not an external one) or the XPS One 2710 touchscreen display is not HDCP compliant.  I'm trying to determine if either of these two conditions exist or if it may be another problem.

Thanks again for your help.

Running into this same issue (HDCP not working on XPS 27 One Touch). No updates from Dell? Pretty glaring issue for an otherwise awesome media-centric PC.

1. WMC will not work (start) in the 2560 x 1440 resolution.

2. Slide over to second monitor at 1920 x 1080 and WMC works and I get all of my channels.

3. I then slide WMC back to the 2560 x 1440 resolution screen and it works great.

Good luck.

Brian,

I just got the XPS 2710 (Windows 😎 last week and ran into the same issue. Thanks to your post I was able to get it somewhat working. From my testing, it seems that any UAC prompt will cause the live tv to start working. Even if you click on "NO" to the UAC prompt, live tv will start working. So basically it has nothing to do with Intel Rapid Storage application, just the UAC prompt when you try to open it will make live tv work.

A quicker way to get live tv working for me is to open WMC Live Tv in windowed mode which will give the error, but then as soon as I expand it to full screen, the channels will work. So its definately a software issue somewhere. Hopefully Dell can find a permanent fix for this.

Also, in case anyone is getting flickering black on live tv for certain channels, you can try the following to fix that issue. Right click on windows desktop, go into the settings for your HD4000. Go to Media, then Image Enhancement, and uncheck the Adaptive Contrast Enhancement.

Hope this helps.

I just bought an XPS One 27 and have the same problem with HD Homerun and WMC, except that none of the suggested solutions work for more than a moment (UAC prompt, starting in a window and then going full screen). I am ready to pull my hair out - we bought this to replace an old HP TouchSmart that worked great. It's a kitchen computer and watching TV is one of the primary usages. This Dell is useless for this.

Has anyone come up with any other ideas?

I would say to make sure you have the updated drivers from Dell and latest bios. Nothing else that I can think of that would make a difference.

This is an issue in Windows Media Center that Dell and MS need to resolve.  WMC does not recognize DisplayPort connections (which presumably the XPS One is using internally to connect the display) as a protected display path, even if they are HDCP compliant.  The only workaround is to use a monitor connected via DVI.

My suggestion would be that either you return the PC and purchase one that does not use DisplayPort, or contact Dell and MS and push them to fix this issue.

I just received my XPS 27 with the Nviada display card. I installed Window 8 Pro with Media Center.

I had the Display Driver error mentioned here when trying to watch Live TV.  This is a real bummer. Media Center was one of the prime uses intended for this machine. It was to replace my old HP Media deskside machine which was 6 yrs old or so.

I spent for hours last night making sure that all the drivers were up to date and all software was up to date.

I finally got it "sort of working"...  I found that after I started Live TV and receive the driver error that if I down sized from Full screen to a window of some size it would begin to work. It even seemed to work the other way around that is to say if I started live TV in a Window and then got the Driver Error I could get it to work by full screening it.  In short, this is not acceptable to me for a maching that cost over $2000.

I spent litterally 4 hours on the phone with Dell today working on this problem. 2 hrs of working with the software people and trying to make them understand what the problem was. They then transfered me to the Hardware people. He was convinced that the Driver was the problem so we tried to uninstall all the graphics drivers Intel 4000 and the Nvidiva 640 driver. We could uninstall both but when we rebooted they both came back again.

The latest attempt is to start over from scratch. I am restoring my machine to factory setting (takes about 4 hrs or so for the utility to reset everything). I will then install Win 8 Pro. Then I will uninstall both drivers again Intel and Nvidia (hopefully they will stay uninstalled this time) . I will then download the Intel Driver from Dell and install.  Next will be the Nvidia driver from them directly.

Well we will see if that works. I suspect it will not but it seems to be the only way to satisfy them that the problem is in the driver/WMC interface.

If I can not get this working correctly, I will return the machine.. Too bad, It is really nice otherwise.
