VTBook DualDisplay is now shipping in two different Editions featuring the must-have VT MultiDisplay software utility. Thanks to the VTBook DualDisplay and VT MultiDisplay you'll be able to enjoy the most complete multidisplay experience possible on a notebook.

You will have the choice to use two different drivers when using VTBook DualDisplay, so please read the driver information for information about how to customize your multidisplay configuration right from the start!

Why should I use VTBook DualDisplay?

If you are using Windows and need more than two external displays connected to your notebook, then VTBook DualDisplay may be the right solution for you.

The DualDisplay cable connects VTBook directly to one VGA and one DVI display bringing the total number of displays connected to the notebook to three (if the notebook has an external video output), for a grand total of four displays including the notebook's internal LCD.
Village Tronic developed two different drivers that make the best use out of the cable.

Which VTBook DualDisplay should I choose?

There are two kinds of VTBook DualDisplay: the Stationary Edition and the Mobile Edition. Depending on which configuration you are planning to use VTBook with, you may prefer one or the other.

VTBook DualDisplay - Stationary Edition

This cable is 1.8m (5.9 feet) long and is designed to be directly connected to the displays. At one end of the cable you can find the DVI-I connector, that plugs into VTBook, and at the other end of the dual cable you can see two male connectors, one VGA and one DVI-D, to plug into the displays.
This is called the "Stationary" edition because it is most conveniently left connected to the displays, in configurations where there is only one 4+ display setup where VTBook is used. This cable is still portable, even if bigger than the Mobile Edition, but you probably would like to avoid to disconnect and reconnect it from the back of the displays every time you connect VTBook to them.
By directly connecting VTBook to the displays, this cable offers the best signal quality.

VTBook DualDisplay - Mobile Edition

This cable is 16cm (6.3 inch) long and has been designed to offer the most mobile solution possible. At one end of the cable you can find the DVI-I connector, that plugs into VTBook, and at the other end of the dual cable you can see two female connectors, one VGA and one DVI-D, to plug into the cables of the displays.
This is called the "Mobile" edition because it is smaller than the Stationary Edition and does not require the user to connect the cable directly to the displays. Every time the notebook with VTBook is placed in a multidisplay location, the cables arriving from the displays can be conveniently connected to this DualDisplay cable.
For this reason this edition is best suited for notebooks that travel between different multidisplay locations or for connecting to Displays which cables are molded to the Display.

Which driver should I use?

Village Tronic currently offers two different drivers to use with VTBook and a VTBook DualDisplay: the Standard driver and the DualDisplay (DH) driver.

The two drivers can't be used at the same time on the same operating system: to switch from one driver to the other you'll need to uninstall the current one and install the other one.

Here is a brief table explaining the main differences between the two drivers:

The DualDisplay driver has been created to give the user a real multidisplay solution: the two displays are seen by Windows as two independent screens.
In order to implement this functionality we've been forced to put some limitations in the current DualDisplay driver:

The Standard driver, on the other hand, is limited in the way it deals with two displays. It implements a set of resolutions to be used with a DualDisplay Cable and two displays that consist in a very wide resolution seen by Windows as a very wide screen. The two physical displays need to be placed side-by-side since they form an unique screen. On the right you can find a detailed description of the two different approaches.

Naming notice: VTBook DualDisplay was also marketed as VTBook DualHead. The two names refer to the same product and functionalities. DualHead™ is a trademark owned by Matrox.

All standard and DualDisplay Windows drivers can be found in the VTBook download page.

DualDisplay vs Virtual DualDisplay

Depending on which VTBook driver you use with VTBook DualDisplay, you'll be able to use DualDisplay resolutions or Virtual DualDisplay resolutions.
Depending on the applications you are using and on your working style you can choose which driver suits best your needs.

DualDisplay Resolutions

Each display connected to VTBook is represented in Windows by a different, independent screen. Displays can be arranged in any position.
This arrangement best suits applications that need multiple separate screens to work properly, as for example financial ones.

Available resolutions:

All resolutions on the VTBook specs not bigger than 1280x1024@60Hz at 16bpp.

Virtual DualDisplay Resolutions

The two displays connected to VTBook are tied together to form an unique screen. The physical position of these displays should always be side-by-side (VGA display on the left) to reflect their relative logical positions.
This arrangement best suits applications that are not designed to work with multiple displays and place all windows in one big enclosing window. A Virtual DualDisplay resolution can trick these applications to use more than one display without knowing.

Available Virtual DualDisplay resolutions:

Required configuration

• First of all you need a CardBus compliant notebook.
  When running two screens, VTBook will use around 3W of power, near to the CardBus specification limit, and we found a few notebooks with limitations to the maximum power supplied to CardBus devices.
  Please refer to the VTBook compatibility page to find the notebook models that we know to have power limitations.
• One VTBook, of course!
• A Windows XP or 2000 installation. If you are using Windows XP, you'll have two drivers to choose from. If you are using Windows 2000 you'll be able to use only the Virtual DualDisplay resolutions using the Standard driver.
• One VGA display. If your display comes with a fixed cable we recommend the Mobile Edition cable to ensure best display quality.
• One DVI display. If your display comes with a fixed cable we recommend the Mobile Edition cable to ensure best display quality.

Important notice: it is not possible to run a dual VGA configuration using a simple DVI-to-VGA adapter (for example the one bundled with VTBook) since the DualDisplay cable outputs a DVI-D digital-only signal.
A dual VGA setup can be only be obtained using a rather pricey DVI-to-VGA converter (not adapter) that converts digital signals to analog signals.
