| 628553 | 2008-01-10 08:13:00 | Digital Rights Management, a dastardly trick wrought by the content suppliers to restrict use of their copyrighted material (DVDs, CDS, downloaded music/mp3s/video etc); Vista is particularly tough on this, plus DRM restrictions are being built into the computer hardware/firmware now, so its quite possible this is causing your problem as the HDMI cable is designed to be a secure system. The forum rules prevent us from telling you how to circumvent this so I would advise you to 'Google' the problem, :2cents: . | feersumendjinn (64) | ||
| 628554 | 2008-01-10 08:15:00 | OK so i tried a HDMI DVD player and HDMI works on the TV so we know its not the HDMI port. whats DRM? Digital Rights Management. But this won't stop Windows from showing up on the TV. |

| 628555 | 2008-01-10 08:21:00 | I have installed all the latest drivers and ATI Catalyst Software and have had it going using component at low res however I can’t get anything to display on HDMI. I think he's had Windows displaying at lo res :) |

| 628556 | 2008-01-10 08:26:00 | DRM wont stop a signal . Macrovision might, (depending on WHAT you were trying to show on a TV), and if you had a Nvidia card and drivers . |

Since it will work at low res, i.e. No HD resolutions then it could well be the TV is not a trusted device. Off cause it could also be the video card and or drivers after all not all HD devices are created equal :) |

| 628559 | 2008-01-11 02:05:00 | I have been doing a similar thing recently, connecting an ASUS EN8500GT/Silent card to a Philips 1080p capable LCD. Using the standard VGA connector the maximum resolution I was able to get was 1360 x 768. Using the HDMI connector I can get 1920 x 1080, but it is pretty hard to read at a typical viewing distance! The ASUS graphics card documentation specifically states support for HDMI so that DRM protected media, eg Bluray, can be played on the PC and displayed on the TV. I take it from this that some graphics cards do not have the necessary support. (Note - the Asus EN8500GT does not have great graphics performance, I got it because it doesn't require a fan, ie silent). I am using XP Pro. | ledzep (1441) | ||
| 628560 | 2008-01-11 02:08:00 | Also, I discovered that the graphics card output is from a DVI-D connector, no audio. The HDMI input on the my TV expects audio to be delivered through the HDMI connector, so if using the PC the audio would need to be routed to a stereo (eg SPDIF connection). The PC input on the TV has VGA connector plus audio input. | ledzep (1441) | ||
| 628561 | 2008-01-11 02:19:00 | Windows Vista (in my limited understanding of it) uses High Definition Content Protection (HDCP) to protect the unauthorised copying of content like DVD's. This means that if you want to view DVD's on an LCD screen, the screen needs to be HDCP-compliant. If it is, Vista understands, and allows the video image to be shown. But if Vista doesn't detect compliance, it believes you might be making an illegal copy of the video... eg, HDMI into a recorder's input. So I expect your TV isn't equipped with this HDCP compliancy (perhaps because you could use the video-out connections to loop through your TV into a recorder. Maybe if you had absolutely no way of recording the TV's image, it would have gained compliance.) It's a bit annoying for consumers, but it protects the copyright of movies, tv shows etc. |

| 628562 | 2008-01-11 03:51:00 | Also, I discovered that the graphics card output is from a DVI-D connector, no audio. The HDMI input on the my TV expects audio to be delivered through the HDMI connector, so if using the PC the audio would need to be routed to a stereo (eg SPDIF connection). The PC input on the TV has VGA connector plus audio input. My TV has an option in the menu that allows you to set where the audio for HDMI is coming from - Either Digital via the HDMI cable or through the PC analogue audio inputs (that are there for anyone using the VGA input) Also as far as I know HDCP is only for video content and has nothing to do with Windows itself so should not stop Windows from showing up on the TV. (If this was the case they would get the BIOS/POST screen then the Vista loading bar and then the screen would go blue.) It is there to stop people playing hi-def video content and making copies of it. Also it won't stop you from playing the video if you don't have HDCP compliance. It will just display it at DVD resolution instead of hi-def. |
