1. HOW DO I SET UP DUAL MONITORS ON MY NVIDIA DISPLAY CARD?
Make sure you have both monitors connected to the system and powered-up before attempting to setup nView.
Then, follow these steps to configure multiple displays with your NVIDIA display card.
- Right click on the desktop and select "Properties"
- In the Display Properties control panel click the "Settings" tab.
- On the bottom right corner of the window click "Advanced...".
- In the Advanced window click the GeForce tab.
- Click the "nView Display Modes" option.
- You must now choose what mode you would like to setup:
- Clone will mirror your primary display to your secondary display: This setting is good for use with a projector.
- Horizontal Span/Vertical Span: This will stretch your display across both displays horizontally or vertically depending on what option you select.
- Once you have selected the option you would like to use, click "Apply".
- Windows will now ask you if you would like to keep these new settings, if you do not click "Yes" within 10 seconds the displays will default back to single monitor and you must repeat the above steps.
2. WHAT IS DIRECTX?
DirectX® is a group of technologies designed to make Windows-based computers an ideal platform for running and displaying applications rich in multimedia elements such as full-color graphics, video, 3-D animation, and surround sound.
The latest versions of DirectX can be found on Microsoft's Windows update page.
3. WHAT ARE THE MAJOR DIFFERENCES BETWEEN THE CONSUMER-LEVEL NVIDIA® GEFORCETM FAMILY AND THE WORKSTATION-CLASS NVIDIA QUADRO® FAMILY?"
Since most consumer applications and games don’t create many pop-up windows, the GeForce family of GPUs supports only one clip region, whereas the NVIDIA Quadro family support up to eight clip regions. This would offer superior performance in applications that open many windows. The NVIDIA Quadro family of GPUs supports clip-plane acceleration in hardware - a significant performance improvement when it is used in professional applications.
Another feature offered by the NVIDIA Quadro family of GPUs is memory management optimization, which efficiently allocates and shares memory resources between concurrent graphics windows and applications. In many situations, this feature directly affects application performance, and so offers demonstrable benefits over the consumer-oriented GeForce GPU family. NVIDIA Quadro memory management optimizations ensure that all available graphics memory is used efficiently, preventing potential performance degradations or loss of functionality because of exhausting graphics memory. This is important for professional applications in both the CAD and DCC markets that use several graphics windows simultaneously, as well as define and use many textures.
Overlay planes let items be drawn on top of the main graphics window without damaging the contents of the windows beneath. Windows drawn in the overlay plane can contain text, graphics, and so on-the same as any normal window. Support for overlay planes is exclusive to the NVIDIA Quadro family of workstation GPUs and allows them to meet the needs of professional applications. Overlays are not supported on the GeForce family of GPUs.
Many workstation applications, particularly in the CAD market, offer the option of using antialiased points and lines (sometimes called "wireframe"). With this option turned on, component edges can be viewed as precisely as possible without encountering the aliasing artifacts that are associated with lines displayed on a rasterized display. Quadro offers antialiased lines in hardware while GeForce does not.
Quadro offers support for OpenGL Logic Operations in hardware. An example of this is a Digital Content Creation application where the XOR logic operation is used to draw sophisticated cursors, such as those in the paint operation of Alias’ Maya application. The XOR logic operation draws the cursor on top of the 3D scene for applications that do not support overplay planes. If the XOR logic operation is enabled, the performance drop of the NVIDIA Quadro is minimal when compared to that of GeForce.
NVIDIA Quadro GPUs provide several additional features and benefits for professional application optimization and certification by Alias, Adobe, Autodesk, Avid, Bentley, Dassault, Discreet, Multigen-Paradigm, Newtek, Nothing Real, Parametric Technology Corp. (PTC), SDRC, Softimage, SolidEdge, SolidWorks, and Unigraphics and others.
Finally, if you are lucky enough to have 3D glasses and an application that supports stero viewing, the NVIDIA Quadro GPU family supports a much faster quad-buffered stereo; the GeForce GPU family does not.
