ATI X850XT - Dual Link DVI Capable?

[Fuzzb3k]

Hi all, I was reading the spec. sheet for the X850XT and it listed this:

Display Features

* Dual integrated display controllers
* Dual integrated 10 bit per channel 400 MHz DACs
* Integrated 165 MHz TMDS transmitter (DVI 1.0 / HDMI compliant and HDCP ready)
* Integrated TV Output support up to 1024x768 resolution
* YPrPb component output for HDTV display connection*
* Single and dual link external TMDS transmitter support for high resolution and/or multi-monitor DVI configurations
* Compatible with ATI?s THEATER? video decode and capture devices for VIVO (Video Input / Video Output) configurations

Now, I have the X850XT card and I looked at the external TDMS transmitter chip and it is a Silicon Image SiL1162 transmitter http://www.siliconimage.com/products/product.aspx?id=5. Looking at the specs. for this, it is only capable of running up to 1600x200, but it does say 3 TDMS data channels.

I am seriously considering buying an Apple 30" HD display and was wondering if this card would drive that panel. I also noticed that the recently announced X800XT for the Mac supports dual link DVI on one of the DVI ports - this card uses a SiL178 transmitter and looks different in shape to the SiL1162.

TDMS always has three data channels on a single link. No news there. The 162, as you figured out already, is a single-link chip.

Unless you see a 2nd TMDS transmitter on the backside, no go.

ATI tech support says officially, no Radeon including the X850 XT supports the 30" resolution at 2560x1600. They are clearly drawing the line in the sand that says you gotta pay FireGL prices to play 30" resolutions with ATI.

The 3100 doesn't have dual link. 5000/7100 or X3 256 models have dual link.

My bad. Disregard then.
