The NVIDIA Control Panel is an application that lets you change the way your NVIDIA video card or graphics card operates. To access the NVIDIA Control Panel, you would open up the Microsoft Windows Control Panel. If you've installed an NVIDIA card in your computer but the Control Panel software is noticeably absent, you can obtain it by downloading and installing the proper device driver for your card.
Open your computer's Web browser and navigate to NVIDIA's official driver download page at nvidia.com/Download/index.aspx?lang=en-us.
Fill out the information requested of you in the drop-down menus on screen. These menus are used to identify your specific NVIDIA product, which will ensure that you download and install the proper device driver. You need to specify the product type, the series the product is from, the unit's exact model number, your operating system and your desired language.
Click "Search." This will bring up a page with device drivers for the NVIDIA product you have specified. Click the "Download" link to download the device driver to your computer.
Double-click your NVIDIA device driver file. Click "Install." This will install the NVIDIA device driver and the NVIDIA Control Panel onto your computer.
Reboot your computer. When Windows loads again you can access the NVIDIA Control Panel through the Windows Control Panel, or by right-clicking on your desktop.
