There are many sites online that offer the Syncmaster 500s Driver, and here is one: http://www.bestdrv.com/samsung_syncmaster_500s_driver_47955.htm.  Another site that has information is http://members.driverguide.com/driver/detail.php?driverid=522. One last one that looks like the best one yet is: http://members.driverguide.com/driver/detail.php?driverid=522.  What I like is that the Syncmaster Drives detect your out-of-date drivers automatically.  This keeps your software running smoothly, and it’s one less thing to worry about.  Figuring out the right updates for your system, on your own, is difficult and frustrating.  If you get the Version Tracker Pro, it scans your hardware and software to access your applications and drivers; then figures out what you need, and you are done.  As soon as new updates are available for your computer, you are alerted.  What a relief to leave these tasks behind, knowing that your system is being reviewed for any compatibility issues, and you don’t have to worry about it.
