A driver for the monitor may be available, but not likely for Windows 10. Chances are that you have upgraded this machine to Windows 10 and did not get it originally this way. What happens with some of the older systems (and they don't have to more than 2 or 3 years old for this) is that there is no specific video driver found for your onboard (or add-on) video card and Win 10 uses the standard VGA driver. This driver has limited resolution options. You need to investigate and determine what video card you have (nVidia, ATI), and what model the card is. Then go to the appropriate site and download the latest drivers from that site for the card you have. Do not worry if they do not list Windows 10 support. Chances are they will work. Install the updated driver package and see if your resolution issues vanish. To see what driver you currently have, right-click on the Windows Icon in the lower left and select Device Manager. Look under Display Adapter to see what Windows 10 has installed for your machine. If it the Standard VGA (generic), you should try to update it as explained above.
