If you plug your monitor to your computer and there's a picture then there's a driver installed in your system. just adjust the setting from the Display Properties. (right click at desktop screen)
To update the driver, From the Display Properties click the following: SETTINGS, ADVANCE, ADAPTER, PROPERTIES, DRIVER, UPDATE DRIVER then select the folder where you save the drivers. If it say it doesn't have digital certificate then make sure you have the right company. It might work but if not working properly then just roll it back to previews driver.
