Dual monitors: DVI and VGA not supported simultaneously
I can use dual monitors with one being the internal screen, but I would like to have two external LCDs connected instead. From what I've read online, it seems the Port Replicator II can't handle DVI and VGA simultaneously, but can I use the VGA on the laptop (Tecra M5) and the DVI on the port replicator?? NVIDIA should be able to handle it, I assume.

The problem could be in the adapter to the video card. There are different types of DVI connections. If the adapter does not have the proper set of pins then the card will not recognize that a monitor is connected at that port. Monitors themselves have no bearing on whether a single or dual monitor set up will work or not.

you need a dvi to vga adapter not a dvi to vga plug and you must also go into your graphics card setup catalyst control center if its ATI Nvidia Display manager for Nvidia if you boot the computer with it pluged in and you can see the boot screen on bolth displays then its an os thing just right click and select the display manager the activate all display's through the managers
Hello ghinea18, sorry you can't do that because this will cause hardware conflict, that's why motherboard bios automatically disable integrated graphics if you install video card using pci express x16 slot - Nvidia GeForce 7300SE. do you know if your video card has dual vga or dual dvi connection?
You can try dual display, im not sure if this card supports dual monitors because nvidia online specs does not show full specs on 7300se series. \

That's quite strange as during system startup you should see the Dell POST logo as at that point the card is only running at VGA, and the monitor will support display at this resolution. If you connect with a normal single DVI cable the monitor should display at 1280x800 also.
Have you tried this? Also have you had this monitor working on another computer at all? What happens if you power up the 3007 with no video cable connected? It should cycle through the pixel test screens. If you are not getting that, and you are not getting the pre POST logo during powerup i suspect that it is a screen failure.
What you probably want is a KVM (Keyboard, Video, Mouse) switch that supports dual monitors. It's a simple device that allows you to plug multiple computers into one set of monitors, keyboard, and mouse and switch between controlling them.
I don't know of any that support mixing analog and digital connections for the monitors, but using a VGA to DVI adapter for one of the monitors should solve that problem cheaply.
