Depending on what graphics card you have installed and what operating system, from time to time, you will need to update your graphics drivers. To help you, we have provided a link to the AMD Support page for graphics cards drivers. These drivers are developed and published by AMD. Below are some example screenshots of how to find the correct drivers for your graphics card and operating system. In general, if you are installing a new graphics card, you will select "Graphics". This is a default selection on AMD's Support page. For this example, we are selecting drivers for an AMD RX 580 graphics card. We have selected Radeon 500 Series > Radeon RX 500 Series > Radeon RX 580. Once this is complete, click "SUBMIT". We are now at the page to select your Operating System (OS). From this page, simply find your OS and click on the name. This will expand the OS driver list to show you the most up to date driver versions available. If you require further assistance or information, please contact our Support team.

If you find that your graphics card is producing “artifacts”, or visual distortion, follow the steps below.

  1. Reseat the graphics card into the PCIe bus.
  2. Reseat your monitor cables on all connections.
    1. If you have alternate cables, monitors, or graphics cards available for troubleshooting, use those to see if the issue persists.
    2. Reinstall your graphics driver.
If your system is producing “blue screens”, or there is an apparent issue with driver software, follow the steps below. Uninstall all AMD software. Run the driver CD included with the card and (immediately after selecting your language) select “Uninstall.” Reboot your system and open Device Manager.    Select Display Adapters, right click and disable any devices you see within it (except for an AMD or VisionTek device).                                                                i.      Within Display Adapters, you are likely to see Standard VGA graphics adapter, your onboard graphics driver, or remote access software.  All must be disabled.                                                              ii.      If your system prompts you to reboot after disabling devices, do not reboot. Proceed with installing the most recent compatible graphics driver. Drivers can be downloaded from or... Read more
Check Your PSU Determine your system’s PSU wattage.  Look at the PSU’s sticker for the maximum output wattage. Contact your system manufacturer directly. Determine your graphics card’s PSU wattage recommendation. Go to and search for your graphics card’s 900XXX P/N.                                                                i.      On the card’s product webpage, select “System Requirements”, and note the card’s PSU wattage recommendation. If your system’s PSU wattage does not meet or exceed the PSU wattage recommendation, you will need to upgrade your system’s PSU in order to use the graphics card in the system. Contact your system manufacturer to find a compatible PSU upgrade that meets or exceeds the graphics card’s PSU wattage recommendation. Checking Your BIOS Shut down your system and remove the graphics card from your system. Plug your monitor into the onboard output, or use a known working graphics card. Boot into your system’s BIOS by following your system manufacturer’s instructions, or referring to your motherboard manual. Take note of the BIOS version used.                                                                i.      Do not attempt to access your system’s BIOS unless you are already familiar with how to use it.                                                              ii.      VisionTek cannot support navigating, modifying, or updating your system’s BIOS. Contact your system manufacturer directly to locate the most recent BIOS update available and for assistance installing it. Test the Graphics Card In A Different System. Shut down your system and remove the graphics card. Install the graphics card in a different system (if available). Following steps above, check the system’s PSU and BIOS to verify it will support the graphics card. If the graphics card displays no output, contact or your vendor directly to process an...

Passive adapters – non active adapters are called passive adapters. there is no easy way to tell the difference between an active and passive adapter. Most often they look exactly alike. Most manufacturers put the word active somewhere on their active adapters, like VisionTek. Though this is not always the case. Rule of thumb is, if it does not say active on the adapter assume it is passive. 

Turn the computer ON and allow Windows to boot normally (Note: the initial resolution will be low due to the graphics drivers not installed). Windows 7 & 8 may automatically install drivers on some older graphics cards.  (Note: Click CANCEL if the “FOUND NEW HARDWARE WIZARD” appears).  Insert the CD that came with the card into your CD/ DVD drive and follow the installer walkthrough. If you do not have a CD/DVD Player, you may download drivers from our Tek Support website or Verify you are installing the correct driver is for your specific product. If the installation menu does not appear, click on ÿ > Computer, double-click on CD/DVD drive with the installation CD. If you downloaded the driver from a website, double click on the file once it has finished downloading. *Note: You may have to Right Click on the software and select “Run as administrator,” [Windows 7 and above, only]. Follow the on-screen instructions to completion.  The software installer will prompt for restart when finished. To confirm installation, open Device Manager; under Display Adapter, it should show the installed graphics card. [Refer to Figures 2 and 3 under... Read more

Active adapters – these adapters have a chip that helps convert video for the GPU. Your GPU will be able to do this for two monitors but an active adapter is needed for more. Active adapters can only be adapter off of a DP or mDP on a graphics card. The reason for this is a feature that DP has that makes it natively active. Should you be connecting a DP monitor to a DP or mDP port on a card active adapters are unnecessary. 

 Cables and Adapters allow you to convert video from one output to another. Some outputs prevent you from converting to another out. The one from of video that can adapt to everything is DisplayPort. Many of VisionTeks cards now come with a DisplayPort or a Mini DisplayPort. These will allow you get an extra monitor per port. But in order to get this extra monitor a special kind or adapter must be used. These adapters are called active adapters.

DVI – this is a digital signal. Also known as single link DVI, it is capable of 1900 x 1200. There are two different types of DVI, DVI-I and DVI-D. DVI-I has a built in component that allows DVI to be converted to VGA. DVI-D does not have this and cannot be converted to VGA.
