Hello,

I am using Mac Pro Quad cores 3GHz (2007 version) with ATI X1900 ordered from Apple. I ordered a 3008WFP (firmware = A02) last week and it has great problems with my Mac.

When I use resolution of 2560x1600, I cannot see the boot screen (Apple logo). During booting Leopard, the whole screen is black but the LED indicator of 3008WFP will change from orange to blue. I even tried to press the menu button but no menu is displayed.

After finishing boot process, I will see the desktop of Leopard. But there are two possible problems:

 1. If wide mode of 3008WFP is set to 1:1, the aspect ratio may be incorrect and I can see two black margins at left and right of screen.

2. If wide mode is set to "aspect" or "fill", a very low resolution may appear. As 3008wFP will stretch image to whole screen with these two wide modes, the content of the screen is unable to read. All the text and image seem broken.

My 3008WFP is already A02. I asked DELL Hong Kong but they cannot give me the reason. And they even do not know what display card can work with Mac.

Is there any problem for display cards other than ATI X1900. What about ATI 2600 , nVidia 8800GT?

But for my applications, ATI 3870 for Mac & PC is the best for me. But DELL cannot confirm if it is compatible or not.

And finally, my Mac does not know the name of 3008WFP. But there is no problem for 2407WFP-HC.

So, I am seeking help here and want to know more from you.

Thanks!!!

Andy
