I'm no computer expert, but I somehow got my monitor to work after installing these files. Don't know which one or ones is/are essential. Let me know if they work for you. It seemed to me that I ended up removing both my Display Adapter and Monitor from the Device Manager list in Control Panel-System-System Properties and then rebooting the system before everything finally worked. At reboot the system detected the monitor as new hardware and automatically installed the driver. Good luck.
