Why this is so, I do not know. On TV, but I can see how the PC boots up, at least until the welcome screen of Windows comes. Then again synonymous TV black, up to a narrow strip in the upper half of the screen.
When I look into the properties of my graphics card going, and then the primary monitor to 1280x768 body, the second car is set to 640x480.

You will be an HDMI compatible television not so readily s.eine connecting graphics card, because graphics cards do not support HDCP and so the handshake can not be built.
The graphics cards are not certified. In terms of the license HDCP is that necessary for the encryption key values anywhere in plaintext form, since otherwise it too easy for example, by a debugger from the drivers could be extracted.
So as long as your graphics card is not in the hardware, that will nix with HDMI (at least not in HD).
In addition, DVI for you anyway need more data line. So this is not modified in any DVI does not.

Content protection capability is recommended for all HDMI compliant devices. An HDMI compliant Source should protect all of the protected audiovisual data. Amongst adequate copy protection technologies that are compatible with HDMI, HDCP is available.

HDCP implementations for HDMI shall adhere to HDCP specification version 1.10.

on the pc & tv an almost identical picture was. But only almost.
and in my opinion, it was again s.der resolution ....

HDCP is a copyright to be seen .... Mr Wedel is important to us so abundantly said that he has no idea what he faselt. Last week I had the same access to more than one, brand new flat TVs. All with Full HD panel. Via DVI-HDMI - s.Notebook (of early 2007) and PC (Model 2006), both with NVidia graphics cards and guaranteed without HDCP support, connected. HDMI input from the TV input is selected - already appears in the video card drivers to the Television and can control.
If, as in the case of the question's origin, does not work, this may be a whole series of reasons - with older TVs Flat-s.PC synonymous, I have gone through all kinds of surprises experienced. Since the Model Year 2008, with the TVs is the so-called A-brands (Panasonic, Philips, Sony, Samsung, etc.) do not stress anymore. And HDCP problems could only play a role if the manufacturer has implemented it wrong - namely, as Mr W. weismachen us wants.
Dear Slashcam: This discussion is once again an excellent example of how Mr. W. unsuspecting visitor of your forum with his false statements to simply Bockhorn hunts. That falls back on you - whether you want to or not. Do you perhaps have a look at last block?
Alternative suggestion: Your pay me for me so far of only cursorily maintained
Antwort von WoWu:
Deti @
Then you have HDCP yet really understood .... because HDCP is a high-speed
hardware - Chiffrierverfahren with 40 keys and a length of 56 bits.
The encryption, which you refer,
Kaitel 3, "Data Encryption" ... concerns only the data channel on which the hardware connection, but not the channels on which content is exchanged. Therefore, the unencrypted content.
You must be a clear distinction between the data channel and the content are different.
Only when the authentication has been carried out properly, the correct Initialisierungswerte for HDCP cipher notes.
After each image will return a reinitialization of Ciphers performed, but (usually) nothing s.Wert of Ciphers should change, unless the key is exchanged.
To avoid running an authenticated device against a non-authenticated is exchanged, reviewed the State Machine in Pollverfahren with HDCP about every 5 seconds the proper status of the counterparts, which fails if the "right" communication partner off or by another device has been replaced.
So it would succeed, the content of the TMDS serial transmission to decode, if he were in fact visible.
For the above reasons, but not succeeding.
Devices that have access to a HDMI / HDCP licensing feature, where but in retrospect it is found that they still access the HD signal, synonymous with post-manipulation) enable are available on the Revocationsliste used in DVD or TV broadcasts sent is subsequently shut down.
HDCP is never in the picture signal, as is often falsely claimed, but is a separate process that already when you turn on hardware works and not only when the content expires.
The necessary process for these key "act" the device in an authentication process, a transfer from s.Beginn.
This authentication provides the rights holder the possibility of abuse of certain equipment to intervene.
Owners of copyright, their contents have been copied illegally, as Manufacturer synonymous with a market disadvantage is that the competitors copy the procedure has not properly implemented, the DCP LLC, a callback, the key of the affected devices to obtain.
So synonymous devices, which according to HDMI VGA promise to work only as long as they are not copyrighted content "see" a revocation lists.
To that extent, therefore, contrary to your assumption, not the usable encrypted, but the authentication process.
I think, therefore I voted for my book pretty accurately researched, in which the proceedings are of course much more accurately described and after over 10 years experience with encryption technology in the TV area synonymous, I think that I have the necessary background experience, such procedures synonymous understand them.
Antwort von deti:
@ WoWu:
Your original formulations have the reader suggests, the data of a HDCP-secured connection is unencrypted. The synonymous sets of the specification you referenced "High-bandwidth Digital Content Protection System - Independent Interface Adaptation" close. This deals exclusively with the HDCP process, without the necessary encryption of data on the TMDS interface address.
So it would succeed, the content of the TMDS serial transmission to decode, if he were in fact visible. Provided you can undo the encryption.
About TMDS, the image data, and each 24-bit word, which it is transmitted, it is with a pseudo-random value verXORed.
"The HDCP cipher generates a new 24-bit word of pseudo-random data for every pixel of HDCP content to be encrypted."
Would you s.klargestellt top of that you have the encryption of user data on the physical layer assumes as given, then I would have said nothing synonymous.
Deti
Antwort von WoWu:
Deti @
I've always said that the
content is not encrypted and the differentiation between content and data channel provided.
So, accurate reading your criticism would have been superfluous.
But some (other) participants HDCP anyway just keep a copy protection method for old "design" and can not even between the different signal types differ.
But I think it is now clear that the content is transmitted unencrypted and the protection only applies to the connection and it is synonymous clear why many monitors do not HD-compatible connection and synonymous in the DVI connection to the data channel completely missing and thus HD connections are not so easily produced.
Antwort von deti:
@ WuWu:
To clarify it again: There is NO way the user data on the TMDS lines, therefore the (unencrypted) content, an HDCP-secured connection read out. Because each 24-bit word of the image, which it is transmitted with a pseudo-random value is verXORed.
Deti
Antwort von WoWu:
Deti @
There is nothing attached to the content and it is synonymous in encrypted manner None.
Is there a connection once, it is only through the parallel data channel secured, however the content referenced time None.
Only this data channel is parallel ge-cyphert.
The TMDS transmission is only a serial transmission method, the signal back into a synonymous parallel signal can be converted and thus be usable. One could therefore describe the quasi-coding, which however contains no safeguards.
So the unencrypted content as described, because any change (and it is only by adding relevant data) is missing. Only the (extra imported) data channel between the hardware elements and the resulting management of the losing unit secure the content from.
The fuse is that you s.die signals are not coming out.
