30" Cinema Display Vsync and Hsync

Question

What are the hsync and vsync values for the 30" display? I'm using it with my linux computer as well, and I'm not sure what to tell it.

Answer 1

Here is a text dump from the EDID contained on a Cinema 30's ROM. The first timing is suitable for single-link DVI and results in a low resolution. The second timing is the Cinema's full resolution but it only works for dual-link DVI enabled graphics cards.
Descriptor #0 is Timing definition:
Mode = 1280 x 800 @ 60Hz
H. Active...............1280 pixels
H. Blanking.............160 pixels
V. Active...............800 lines

HSync Offset............48 pixels
HSync Pulse Width.......32 pixels
VSync Offset............3 lines
VSync Pulse Width.......6 lines

Non-Interlaced
Sync: Digital separate with
* Positive vertical polarity
* Negative horizontal polarity
