ATI Radeon 9000 Mobility

[lightweight]

I have a Dell D600 laptop with an ATI Radeon 9000 Mobility card hooked to a D600 docking station. The docking station has a VGA and DVI input. I've got a DVI -> Dual DVI cable and have 2 monitors hooked up to it now. The best that I can get is the same display on both screens. What I want is to have one screen "extend" so I have more space to work. Is this configuration possible?

The desktop extension is available using the laptop's display + 1 monitor, no idea about using the docking station. Did you RTFM?

Did you try using the VGA output for one of the monitors?

The only thing you may be able to do is have the VGA & DVI port outputs extended, you cannot control that only going out to one port and splitting it. Your splitter is a dumb device, it does not have any capability to control that and your laptop does not know you have two displays hooked up. Unfortunately ATI's dual monitor options are pretty crappy IMO.

We have a review forthcoming on it, it is a pretty neat device.

The mobile R9000 has two output pipes, yes. The implementation is up to the machine's design. I'd expect one output to be used for the internal panel, and the other going to the external port.

Thanks for a very helpful post. It looks like this product from Matrox is the solution to the problem. I can just plug 2 vga cables from my monitors into it, and a vga cable to my D600 docking station and it should give me the functionality I need. Thanks again!
