NVIDIA G80 does not play HDCP content at dual-link resolutions

[zekrahminator]

All recent cards from both NVIDIA and AMD(ATI) have the ability to decode HDCP content. However, all recent cards are limited to playing HDCP content in single-link resolutions. This means that they cannot play HDCP content at a resolution higher then what can be attained through a single DVI connection. The G80 cannot play HDCP content on a double-link, or two DVI, connection. And so, anyone buying an HD DVD or Blu-ray player, each which require an HDCP decoder, cannot view content at much higher resolutions then 1080P (1920x1080). R600 allows for HDCP playback on a dual link connection, which translates to a maximum playback resolution of 2048 x 1536.

ati has always been ahead when it comes to HD playback...

It doesn't matter, 1080P is good enough, that is what the content is at so anything higher is just taking a 1080P and stretching it. You can take a 640x480 picture and stretch it to 2048x1536, but it will still look like a 640x480 picture.

no 1080p is not good enough, and good job on AMD(ATI) part for incorperating dual like 1080p HD play back.

 

[newtekie1]

Yes, it really is. It is useless to display 1080p content at anything higher then 1080p, it all looks the same, in fact it can looks worse depending on the scaler used. And by the time the content excedes 1080p the G80/R600 will be just a memory.

Ditto, unless someone can explain to me otherwise.

what you all dont realize is there are people with those shiney 30" apple lcds who have to run dual link to get their res. sure the video will only be 1080p but going from 1920x1080 video res, 1920x1080 monitor res to 640x480 video res, 2048x1536 monitor res....and that is going to look horrible!

How will this affect LCD projectors

Would a 1080P HDCP single link front LCD projector still output 1920x1080?

Thanks

 

[newtekie1]

Yes

Frames persecond

How many frames per second does this card put out?
Can it be adjusted to match a specific LCD front projectors?
1080P @ 24, 50 & 60?

Thanks

Single / Dual Link

Gamers with capable LCd monitors will want the maximum obtainable resolutions w/ dual link.

Gamers with front projectors limited to 1080P will be very happy with single link 1920x1080.

A consumer can choose to wait for ATI to see which best suits their needs.

Peresonally I want to become a front projector gamer and am waiting for a HOT 1920x1080
(1080P) HDCP front projector to hit my price range 4K.
By that time it will be known if ATI or NVIDIA will work best for me.

Now I have time for more research to determine if I can actually get 1920x1080 with this
combination.
