NVIDIA Control Panel
The NVIDIA Control Panel is a tool created by NVIDIA designed to allow you to customise various settings for your NVIDIA graphics card. A similar tool is available for ATI graphics cards, the Catalyst Control Center, or VISION Engine Control Center. By using the Control Panel, you can modify various graphics card settings such as stereoscopic 3D and desktop size and position as well as force certain graphics options such as anti-aliasing and anisotropic filtering.
 Simple Modifications
 Adjusting Desktop Colour Settings
To modify the colour settings which your monitor renders with, locate the
Display menu in the left hand tab and click on the
Adjust desktop colour settings option. This will bring up another menu with various options. If you wish to modify settings for all applications, ensure to check the 'Use NVIDIA settings' box before continuing. The definitions of each subsequent option are as follows:
- Brightness: Quite literally the brightness of your screen. It is important to note that brightness is somewhat tied to the gamma value - if you modify the brightness value by an extreme amount, it will limit the range of gamma values your monitor can display for that brightness.
- Colour channel: This allows you to modify Brightness, Contrast and Gamma values for individual colour channels. Each channel is a 'component' of the display, and computer monitors use three channels - RGB or Red, Green and Blue. This means that the image you see on your screen consists of three images; one red, one green and one blue, which when combined in different ways produce the image you see on the screen. By editing each channel individually you can fine-tune the brightness and contrast of single components of your display image, allowing you to more accurately obtain colour settings you are happy with. Generally however, it is advised you modify the settings for 'All Channels', as this will still allow you to achieve a wide range of effects.
- Contrast: Contrast is the difference, or contrast, between the colours your screen displays. Increasing this value with increase the vibrancy of all colours and the ease with which you can distinguish them. Generally, you will want to avoid setting this too high or too low as it will strain your eyesight during extended play.
- Gamma: Gamma, or gamma correction, is an operation your computer carries out to determine luminance settings for images. In simpler terms, it 'optimises' images displayed on your computer to emphasise colour differences the human eye is sensitive to (for example, shadows) and to prevent storage from being wasted on distinguishing colour differences the human eye struggles to detect. Generally speaking it is advised you leave this value at the default +1.00 setting.
Several image enhancements are also available:
- Digital vibrance: This setting essentially acts like contrast, allowing you to fine tune the way your monitor displays the vibrancy of colours with values between grayscale and a high-contrast setting.
- Hue: This is the amount an image is 'shifted' on the colour spectrum towards one of the unique hues (red, green, blue and yellow).
 Adjusting Desktop Size & Position
By heading to the
Adjust desktop size and position page under the
Display submenu, it is possible to modify how your desktop scales to your monitor resolution as well as the position of the desktop on the display. The 'Scaling' tab allows to adjust the former, with several options available:
- Aspect ratio: This option will scale up the desktop to fit the monitor whilst maintaining the desktops aspect ratio. Thus, if you have previously changed your desktop aspect ratio and it differs from that of your monitor display, black bars will appear at the left/right or top/bottom of the display.
- Full-screen: This option will stretch the desktop to fit the display, regardless of the desktop aspect ratio. If your desktop aspect ratio differs from that of your display, your desktop will appear stretched disproportionately.
- No scaling: This option will not scale your desktop at all, instead centering it at the middle of the display.
Note that if you wish for these options to apply to your games as well, you will need to check the box for 'Override the scaling mode set by games and programs'. Additionally, the Position tab allows you to modify the position of the desktop on the display in four directions.
 Changing Monitor Resolution
One of the ways to change the resolution your monitor displays at is to edit it via the Control Panel. To do this, navigate to the
Display drop-down in the left hand tab before selecting the
Change resolution option. Select a resolution from the drop down list. Your default resolution will be listed with the suffix '(native)'. If you are using multiple monitors you can easily change between settings for each monitor by clicking on the monitor icons towards the top of the screen. By clicking the 'Customize...' button, you can create custom resolutions for your screen to render at.
Also note that this sub-menu allows you to change the refresh rate, or vertical scan rate, of your monitor. This is the number of times in a second that your monitor will 'draw' data, so it can be thought of as a 'frames per second' for your monitor, except it is measured in Hertz, or Hz. Generally speaking you will want to use the highest refresh rate value your monitor can render.
 Modifying Default Graphics Stance
It is possible to set a default 'stance' for 3D rendering via the NVIDIA Control Panel for all 3D applications with regards to graphical quality. This means many games will detect the stance you set - either Performance, Balanced or Quality-orientated, and adjust graphics settings appropriately. To do this, select
Adjust image settings with preview from the left hand tab under
3D Settings. 3 options will appear:
- Let the 3D application decide: This option essentially prevents the Control Panel from overriding graphics settings that a game might decide is suitable for your computer, or the default graphics settings a game loads up with. Choose this option if you wish to fine-tune graphics settings manually to best optimise performance and quality.
- Use the advanced 3D image settings: This option forces all 3D applications to conform to the detailed rules you can set up under
Manage 3D Settings. If you modify these advanced settings be sure to enable this option to see them enabled in-game.
- Use my preference emphasising: Choosing this option enables a slider which allows you to quickly choose to focus graphics on performance or quality, or a compromise between the two. The Control Panel will then ensure that 3D applications are set up to conform to your choice.
 Rotating the Display
By navigating to the
Display drop-down in the left hand tab and selecting
Rotate display, it is possible to change the orientation of your display using the selectable list.
 Setting up Multiple Displays
To enable multiple monitors for use with your computer, navigate to the
Display drop-down in the left hand menu, and select
Set up multiple displays. A list of all monitors that your computer recognises as connected to the system will appear - simply tick the boxes for the monitors you wish to enable and drag them into the box below to determine your monitor layout. If you do not see some monitors in the list, ensure that the adapter connecting your monitor to the computer is properly inserted at both ends.
Note that by pressing the 'Display' tab at the top of the screen and clicking 'Identify Displays', the Control Panel will show you an on-screen representation of your display layout on each monitor, numbered 1, 2, 3, etc.
 Advanced Modifications
 Modifying Advanced 3D Settings
It is possible to set various graphics options for individual applications and processes via the Control Panel. To do so, navigate to the
3D Settings sub-menu in the left hand tab, and select
Manage 3D Settings. Two tabs will become available - Global Settings and Program Settings. Changes made to Global Settings will affect all applicable programs, whereas the Program Settings tab allows you to modify settings specific to individual programs or applications.
To modify settings for a specific program, go to the Program Settings tab and use the drop down to select a program. If the program you wish to modify settings for is not listed, click the 'Add' box and a file window will appear, allowing you to browse for the relevant executable. Below this is a scrollable box with various graphics settings for the selected program, with the 'Setting' column giving various options for this graphics process and informing you if the option is not available for the selected application.
If you modify settings for an individual game, ensure to check the 'Use the advanced 3D image settings' box under
Adjust image settings with preview for your changes to take effect for the application.
 Forcing Anti-Aliasing/Anisotropic Filtering
Some games which do not have native support for anti-aliasing or anisotropic filtering can have the setting 'forced' from the Control Panel; that is the setting can be enabled via the GPU directly rather than through the game. It is a relatively simple process to enable these, and any other graphics features available via the Control Panel. Ensure you have the relevant game selected under Program Settings, and locate the 'Antialiasing - Mode' or 'Anisotropic filtering' options in the list. By default, these will be set to the 'Use global setting (Application controlled)' setting - this essentially means that the option set in-game will determine whether anti-aliasing is enabled or not. Obviously for games which do not have an in-game option, this will mean that no antialiasing is enabled.
For anisotropic filtering, simply click the drop down and select a degree of anisotropic filtering from the list. For anti-aliasing, select the 'Override any application setting' option before using the dropdown next to 'Antialiasing - Setting' to determine the degree of anti-aliasing forced for that application. Applications which do not support these features will list these features as 'Not supported for this application'. Remember to check the 'Use the advanced 3D image settings' box under
Adjust image settings with preview for your changes to take effect for the application.
 Setting PhysX Processor
- For information on enabling PhysX with a primary AMD GPU, see this article.
NVIDIA PhysX is a GPU or CPU-based physics engine which massively improves the realism in the way which supported games simulate real-life physics. It can prove GPU or CPU-intensive on lower systems, and so it is not advised you enable it on lower-end systems, even if your graphics card supports it. If you wish to enable it, however, and are running an SLI/CrossFire setup, or wish to switch between running it using your CPU/GPU, navigate to
3D Settings -> Set PhysX configuration to change your PhysX processor. From here, simply use the drop down to select which GPU or CPU to use to run PhysX. Auto-select will automatically choose the GPU or CPU most capable of running the engine.
 Setting up Stereoscopic 3D
If your GPU is NVIDIA 3D Vision-enabled, you can enable stereoscopic 3D in games, provided you have appropriate 3D glasses. To do so, navigate to the
Stereoscopic 3D menu in the left hand tab, and select
Set up stereoscopic 3D. By enabling it, you will launch the NVIDIA 3D Vision Wizard which will guide you through the setup process, before allowing you to change certain parameters for 3D Vision such as the depth value of the stereoscopic 3D, which decides the extremity of 3D rendered during games.
Before you play a game using this mode, however, check the
View compatability with games page, which provides an extensive list of games which support the feature and any graphical issues you may encounter running those games in this mode.
