And at higher resolutions? Like with Dell's new Apple cinema display 'killer' http://home.businesswire.com/portal/site/google/index.jsp?ndmViewId=news_view&newsId=20060105005993&newsLang=en http://www.engadget.com/2005/12/21/the-dell-3007wfp-to-drop-jan-5th/ http://www1.us.dell.com/content/topics/topic.aspx/global/products/monitors/topics/en/monitor_3007wfp?c=us&l=en&s=gen Aren't those cards intended to be used with rgb sources aka personal computers... Of course they are a great match for any HD HTPC, playing YCbCr, instead of converting dvd source's YUV to RGB. Though I just read that Nvidia's new h.264 decompression accelleration has an edge on ATi's, allowing lower spec cards to accelerate hd signals, whereas ATi's relies on a certain number of pixelpipes to be present, so only the high-end cards can provide sufficient accelleration support. It is said that MS recommends ATi graphics for Vista, due to better driver support. So no clear cut pc graphics leader at the moment. d. ----- Original Message ----- From: "Jeroen Stessen" <jeroen.stessen@xxxxxxxxxxx> To: <opendtv@xxxxxxxxxxxxx> Sent: Thursday, January 05, 2006 12:37 PM Subject: [opendtv] Re: Motorola Introduces First All-Digital Set-Top Family With Built-In Home Media Networking Capabilities Hello, Richard Hollandsworth wrote: > Is there any current HDTV that isn't backward compatible with 24-bit DVI interface via HDMI > (Type A) interface....and NO MORE????

Not true... because of YCbCr 4:2:2 sub-sampling, 12-bits YCbCr costs as much bitrate as 8-bits RGB 4:4:4. And then 165 MHz pixel clock is still enough for 1080p resolution, so a single link will do. Note that ATI are saying that all their X1000 (1300, 1600, 1800) cards have dual-link DVI output, and full 10-bits processing in the output path, and that they can actually connect to a 10-bits (or more) digital display. This is the first good application of dual-link that I have heard of. But you need this only for RGB, not for YCbCr.
