Windows 7: Please Help! Issue with Dual Monitors connected to Laptop.

Windows 7 Home Premium 32Bit (Laptop)
Please Help! Issue with Dual Monitors connected to Laptop.

Hi there guys, my name is James. I'm new to 7 Forums so please help me out! :)
In my work office I have dual monitors connected to a single desktop computer via DVI. I usually work both at work and home so I use my laptop alot. When I'm at home I need more desktop space so I bought 2 cheap monitors that only support VGA inputs. But because I'm using a laptop I only have 1 VGA panel. I have bought a USB 3.0 to VGA adapter and I have installed all necessary drivers to run it. So here is my issue with my display.

In the Resolution Settings it shows 3 displays. 1 Saying Mobile PC Display, 2 saying HP vs17 (My Monitor) and 3 saying Generic Non-PnP Monitor. There is nothing wrong with the monitor as it worked fine on my old windows 7 laptop. There are 2 issues here:
1.) The second monitor is called Generic Non-PnP Monitor and it's default resolution is 800x600 even though it's native resolution is 1024x1024.

2.) The screen is not being displayed even though my computer thinks it is being displayed.

If anyone can help me with my issues it will be much appreciated. I will list some basic specs and If you need any more description details feel free to ask.

OS: Microsoft Windows 7 Home Premium
PROCESSOR: Intel Core 2 CPU T5500 @ 1.66 GHz 1.66 GHz or Intel Centrino Duo
RAM: 3.00 GB
SYSTEM: 32 Bit Operating System
WINDOWS ACTIVATION: Windows is Activated and is Genuine.

Thanks in advance for helping!! Look forward to hearing from you guys!

Hey guys just a quick update here, I figured out the problem.
My USB to VGA cord. That for some reason only allows me to use screens at a resolution of 800x600. Is there any way to change this?
Kind regards,

Hi there

unfortunately that's probably a HARDWARE restriction of the card itself. You might need to source a better card.

I think if you press the windows key + P you should be able to see the monitors - and select whether to replicate the display on each or extend or whatever.

For actual use of the displays your application software probably needs to have some sort of multi-monitor settings too - such as "Stock Market" trading programs etc where multi screens are the norm -- usually 3 as a minimum and often 5 or even 6.

Remember also the video card in your laptop has to be capable of delivering the video output -- Most older laptops IMO won't drive 3 screens simultaneously (although I could be wrong on that one).

Cheers Jimbo

Thanks so much for replying Jimbo! I do see your explanation and I do believe you are somewhat right. My laptop is very old and It may not support extended monitors. As I have used a friend's Windows 8 Acer with Intel i5 and connected it up with the setup I need. It has worked with no issues on my friend's PC. If this is the case I will be ordering a Windows 8 Laptop with i5 xD.

Thanks again for all your help! I do owe ya one!
Just a question: Do you run Extended displays from a single Laptop? Thanks,

Your man,

Try also both the Display software package from it's Support Downloads webpage (packaged normally with driver) and try Win7's native display manager on the right click context menu when you click on an empty area of Desktop.
