In the window that appears go to the tab "Display". In this window you can see information about the video card, namely its name and manufacturer. If you have no drivers installed, it will be written N/A or N/D, then you will need to look for information in your computer documentation.

On this same tab you will have the information about the devices. Usually, a new version is released every one or two months. So if your driver is more than two months, then you need to update it.
Useful advice
You can download drivers from the manufacturer website of the graphics card. They're laid out in free access for download. Usually you only run .exe file, and all the rest of the operating system will do. If after installing the new drivers in the video card began to show some glitches, it is best to return the older version of the drivers. The operating system has the service "system Restore".
