ATI 7670 Mobility - More than two monitors possible?

post #1 of 6
Thread Starter 
Hi there.
I have a toshiba satellite laptop with a amd 7670m and i'd like to have three monitors available.
Right now i'm using the vga port to connect to a 17" LCD, but I have another 19" that I would also like to use for a three monitor setup while at home.

I tried connecting a 3rd monitor through HDMI ( my living room Samsung LCD) and the laptop would go black and show no image until I disconnected one of the monitors.

Is the only way around this a usb video card?

It's not for gaming , just so i can have Pro Tools 10 and other DAW's expanded with all the plugins and stuff showing and easy acessible like this:

Well heres the thing. DVI and HDMI use clocks that are set at certain speeds to handle information because they are digital. Modern GPU's only have clocks for 2 at a time. If I had to guess your laptop screen uses one of those and the HDMI used the second. If you have a display port you could try to use an active adaptor to get the third monitor. Theoretically the GPU should drive up to 5 monitors so I cant see it being a problem

The laptop does not have a display port.
So usb is the only way uh?
Damn companies and not putting all the available ports on laptops! rolleyes.gif

Well it is a constrained location. I am no pro on this stuff so maybe wait on a professional in this section but if your cpu is an apu see if you can set your laptop display to that and the gpu to output to the extra monitors
