Dual Monitors via USB 2.0


I am having trouble connecting dual monitors. My computer has only one VGA output so I bought a USB VGA 2.0 to use to connect my second monitor (26 inch LCD screen). I have updated the drivers, but when I go to Display Settings, only one monitor is being shown. I am having trouble finding any online troubleshooting guides. I am not sure what to try next. Can anyone offer any ideas? Here is what I am running:

Here is a link to the USB device that I have:

Windows VISTA
HP a6200n
AMD Athlon (tm) 64 X2 Dual Core Processor 5000+ 2.60 GHz
RAM: 2942 MB
32-bit Operating System

My graphics cards info:
Generic PNP Monitor on NVIDIA GeForce 6150SE n Force 430
DAC Type: Integrated RAMDAC
Adapter String: GeForce 6150SE n Force 430
Bios Information: Version
Total Available Graphics Memory: 1343 MB
Dedicated Video Memory: 128 MB
System Video Memory: 0 MB
Shared System Memory: 1215 MB

I am new to this forum, so if I left anything important out, please let me know and I will include that information.

Vista was not listed at that link.

"Windows 2000 / XP compatible"

Oops. Return it for something that lists Vista.

I just searched and found that link. That is not the place I bought it from. I bought it off ebay, and the seller had it listed as VISTA compatible. So, I searched to find other dealers, and found this website:

This one has it listed as Vista compatible. It appears to be the same device that I have.

I guess that it may not be compatible, but I hate to toss it aside if that is not it.

when you plug in the device, what happens?

In reply to: Dual Monitors via USB 2.0

what type of device appears in device manager? you should get a new "Display Adapter." if not, something's up with your usb device detection and/or driver.

it shows up...

In reply to: when you plug in the device, what happens?

In device manager, it shows up under USB controllers as "USB 2.0 VGA DEVICE-1", but it does not show up under the display adapters heading. The display adapter reads "NVIDIA GeForce 6150SE nForce 430" only.

did you install the drivers before plugging in the device?

In reply to: it shows up...

if you don't have another display adapter show up, then the driver install is bad.

delete the video device you mentioned in device manager. then unplug the video device and reboot. install the provided drivers and then plug in the video device. do you get a new display adapter?

It worked! Thanks for your help. That's what I get for being impatient when taking a new gadget out of its box. I will keep that in mind for next time. Thanks again!!
