New Mac Pro with Gateway XHD3000 monitor, PIP

Anyone have experience using this Gateway 30" monitor with the Mac Pro. I bought this monitor so I could do Picture in Picture with my cable TV box. The one stipulation with the monitor is that you must be running in full 2560 x 1600 in order for PIP to work. Unfortunately the PIP settings are grayed out when I try to set it up. Gateway support was barely even aware that they sell this monitor and after an hour or so I just gave up. I have a theory as to what my problem is, but I'm looking for some help.

I am using Dual link DVI cables with all 24 pins and my graphics card is the stock ATI Radeon HD 2600. When I boot the computer a box appears on the screen (I'm assuming this is coming from the monitor) saying the resolution is 1280 x 800. After I select my user account and log into the system the box reappears and says I am running at 2560 x 1600. My theory is that the monitor is seeing that original 1280 x 800 from the graphics card and is thus not allowing PIP. Just a theory. Would love to hear from other owners of this monitor or anyone who can help.

Thanks

dzeman,

Great news, happy to hear it's working. I still don't have mine working.

I can watch cable no problem by selecting HDMI and I can use DVI to work on the Mac Pro at 2560 x 1600, but when I turn on PIP it comes up as a blank black box and a message pops up that says "Input Not Available".

Any ideas?

Thanks,

Keith
