Did you or anyone else btw try the Realtek HDMI drivers?

Still scheduled for Dec 2010

Good news for AMD fans, the Antilles dual chip card will end up with two Cayman chips, something that promises that the card can end up significantly faster than dual-chip Radeon HD 5970.

Two Barts (Radeon HD 6850 or 6870) class chips would not be enough to provide a sufficient performance lead for the new Radeon HD 6990 X2 card. This is why ATI is using two Cayman chips and we also learned that the chip looks more like the Radeon HD 6950.

The funny part is that we still don't exactly know what is behind Cayman, but we are doing our best to find out before November 22nd, the alleged launch date.

We expect TDPs around 300W but this is something that can only be confirmed at a later date. It will be very fast, that is certain, but we still don't know who will win this winter graphics update showdown.

256-bit

Information about AMD's upcoming Cayman core is still hard come by, but we have at least one new fact that we can rely on.

Cayman has 2GB of GDDR5 memory and the controller of choice is 256-bit. While in terms of RAM quantity the card beats Nvidia's GTX 580 which has 1.5GB, we can definitely say anything over 1GB is overkill for most users, but it looks good for marketing purposes.

Despite its 256-bit bus, Cayman Radeon HD 6970 looks to be quite close to GTX 580 performance, but we still don't have anything better than this claim. Launch appears to be set for the week of November 22nd and samples are supposed to get to AMD selected press very soon.

I try to direct the deep coloer with the card

It works only with HDMI cable and tv Supporter x.v coloer and deep coloer


Unfortunately I found that different manufacturers of graphics cards
Save money by buying Connector HDMI without support at
deep coloer .

They also do not advertise this option in the card or Level of deep coloer 30 bit / 36 bit/ 48 bit :
only in amd web :

Note that a given product may choose to implement a subset of the given HDMI version. Certain features such as Deep Color and xvYCC support are optional

card manufacturers like gigabyte or HIS or Sapphire buy a cheap HDMI connector that not gives as full value from the card
gigabyte with 4850 hd supports in deep coloer / x.v coloer
But in the following Series are saving Money.

deep coloer and x.v coloer
Give depth to movies, Web sites
By the depth of color, black seems deeper , High contrast

People buy with good money and manufacturers are laughing at them !

The claim that some manufacturers don't include Deep Color support is most likely wrong. Like the 5000 series, all the cards should have it. If it's actually doing something useful is another matter, but there shoudn't be differences between manufacturers.
