30" Cinema Display Vsync and Hsync

The 30" displays are a joke. Mine has not been working right for a while and nobody at Apple will do anything about it.

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
V. Blanking.............23 lines
HSync Offset............48 pixels
HSync Pulse Width.......32 pixels
VSync Offset............3 lines
VSync Pulse Width.......6 lines
Pixel Clock.............71.00MHz
Horizontal freq.........49.31kHz
Vertical freq...........59.91Hz
H Image Size............641mm
V Image Size............401mm
H Border................0 pixels
V Border................0 lines
Non-Interlaced
Sync: Digital separate with
* Positive vertical polarity
* Negative horizontal polarity

Descriptor #1 is Timing definition:
Mode = 2560 x 1600 @ 60Hz
H. Active...............2560 pixels
H. Blanking.............160 pixels
V. Active...............1600 lines
V. Blanking.............46 lines
HSync Offset............48 pixels
HSync Pulse Width.......32 pixels
VSync Offset............3 lines
VSync Pulse Width.......6 lines
Pixel Clock.............268.00MHz
Horizontal freq.........98.53kHz
Vertical freq...........59.86Hz
H Image Size............641mm
V Image Size............401mm
H Border................0 pixels
V Border................0 lines
Non-Interlaced
Sync: Digital separate with
* Positive vertical polarity
* Negative horizontal polarity

hi,
is there any way to "Hack" the 30" display to think 1920x1200 is a single link connection?
Back ground.... the 30" display thinks that 1920x1200 is a dual link connection and as we all know its NOT!

Can't be done. The 30" ACD does not have a scaler chip inside of it. It doesn't really process the input at all. It just passes it straight through to the timing controller. It can do simple pixel doubling, hence the ability to display 1280 x 800, which is half the resolution of the panel in either direction, horizontal and vertical. But it can't scale 1920 x 1200, nor can it process that timing in any way. No hack exists.
