1. Detect My Video Card Online

My C# application sits on the embedded box which has Intel motherboard and graphics chipset. ATI graphics card is put on to PCI express. Generally graphics card drives the video, but if ATI card fails then the video comes out from graphics chipset.

I have to detect the failure of ATI graphics card for diagnostic purposes.

We have received many requests from our readers about credit card validation on client side so today in this tutorial I am going to show you that how to detect and validate a credit card using a jQuery library. It will show you type of detected credit card and calculate the length of the credit card number by its type.

This should hopefully get you started.

Add a reference to System.Management, then you can do this:

In my case, graphicsCard is equal to

NVIDIA GeForce 8400 GS (Microsoft Corporation - WDDM v1.1)

I'm not a fan of how the selected answer only returns the first video controller. Also, there's no need to loop over all the properties. Just get the ones you need. If CurrentBitsPerPixel is not null, then you're looking at one of the active controllers. I'm using Win32_VideoController as suggested by @bairog, instead of the deprecated Win32_DisplayConfiguration.

My machine has 3 video controllers. The first one is not active (ShoreTel). The second one is active, but is not the video card (Desktop Authority). The third one is my NVidia. This code will print out both the DA controller and the NVidia controller.

Promoted answer works only for single video card system. When I have ATI and Nvidia cards - WMI query returns ATI even if that monitor is plugged into Nvidia card, dxdiag shows Nvidia and games runs on that card (usage).

The only way I could determine right video card was using SlimDX to create DX device and examine what card it used. However that .dll weights over 3Mb.

Your question isn't entirely clear, so I'm not sure if the follwing idea will help or not.

Perhaps something very simple would suffice:

If the two graphics cards run different resolutions check the monitor resolution using:

Similarly, if one card supports more than one monitor, check the number of monitors using SystemInformation.MonitorCount.

I tried all the approaches in this question but none gives me a correct answer. However I found it possible to get your current using the Win32_DisplayControllerConfiguration class. Although according to MSDN this class is obsolete, it's the only one returning a correct answer:

(Code generated by WMI Code Creator, a great tool if you are messing with WMI.)

This gives GeForce GTX 1080 on my Windows 10 (RS2) + Intel(R) HD Graphics 4600 + NVIDIA GeForce GTX 1080 system.

Although many PCs come with video features built in, you may get better performance from your computer by adding your own graphics card. Because video technology has evolved rapidly, and card features vary widely, you may need to consider a few different strategies to get your computer to auto detect the card. Your computer’s BIOS setup provides the first avenue for detecting the card. You might also use Windows to detect it, or software provided by the card’s vendor.

Detect My Graphics Card (BIOS)

Restart the computer. In the first few seconds of startup, the PC will display a message telling you to press a function key(such as F1) to enter its setup mode. Press the key when you see the message.

Navigate through the setup menu using the arrow keys until you find a section such as On-board Devices, Integrated Peripherals, Advanced or Video. Look for a menu that enables or disables graphics card detection. If it’s disabled, use the menu to enable it; otherwise leave it alone. For example, you might press the left arrow key to change 'Disabled' to 'Enabled.' Save the changes and exit by pressing the Escape (Esc) key, and follow the on-screen instructions to quit the Setup mode.

Detect From Windows

Microsoft’s Windows 10 can also detect your video card and shows the information in the Device Manager. To see the card in Windows 10, perform these steps:

• Type Device Manager in the search box in the Task Bar.
  
• Click Device Manager from the results menu when it appears. When Device Manager opens, it displays a list of device categories.
  
• Click the icon for Display Adapters to expand it. Your card may appear as Microsoft Basic Display Adapter or it might appear with the video card vendor’s name and model number.
  
• Right-click the appropriate Display Adapter icon and select Properties from the menu that appears.
  
• Click the tabs(General, Driver, Details, Events, Resources) to see the information for the graphics card. The Driver tab lets you update, enable, disable, uninstall or roll the card’s driver software back to a previous version.
  
• Click OK to close the Properties window.

Detect From Utility

Some graphics card vendors provide utility software on their website. This software may check your computer for suitability – it’s important to know the card will work with your PC before you buy. The utility software may also find the card if it's installed and detect the GPU, or Graphics Processing Unit.

Vendor software typically comes in one of two forms: a simple web page button or a program you download from a link. Follow the instructions on the manufacturer’s webpage.

The web page button method is simple: just click the button, wait for the cloud-based software to analyze your PC, and read the informational message that appears.

For the installable program, perform these steps:

• Click the link for the software that matches your version of Windows, such as Windows 10, 64-bit.
• Save the downloaded file to your Downloads folder.
• Double-click the file to install it, and enter your password if prompted.
• Follow the installation instructions.
• Click the utility’s icon to run the program, and wait for it to display results.

Warning

• Make sure you install an appropriate graphics card driver, if you haven’t already done so. The display may appear distorted until you do.

Tip

• If you experience difficulties with your graphics card in the Windows Device Manager, you may need to remove the device driver for the card, then reinstall the driver.
