ATI 4870 and eizo sx3031

[stefand]

Dear All,
6 weeks ago I bought a Mac Pro Dual Quad 2,66 with an ATI HD 4870 graphic adapter. System is OS X 10.5.7. I try to get an Eizo 30" display (SX 3031W) working with this configuration. Using the signal connector #1 on the Eizo , the display will show up to 2560x1600 resolution (as it should be) but after selecting this option will fall back to 1600x1200 pixel.
I tried installing on the DVI plug of the card and also on the minidisplay-port using the "Mini Displayport to Dual Link DVI adapter" from Apple but up to now it does not work.

Any suggestions would be appreciated deepest...

ATI 4870 with Eizo SX3031 - problem solved

Dear All,
problem solved:
It had been the Dual Link DVI cable attached "wrong" side to the Eizo.
Be sure to use the end with 6 pins more to attach to the monitor, the other end with the pins missing to the graphic card.
Then it will show a smooth image at 2560x16000.
In the happy moment of setting up the system I did not look at these tiny detail...
