Cross check and make sure that you are following below steps

• Right click your monitor listed in device manager > click on "Update" > Double click on the monitor listed > click on the "Driver tab" and click on the "Update Driver button"
• After that select "No, not this time" and select "Install from a list or specific location ( Advanced )"
• In the Next windows select "Don't search, I will choose the driver to install" and click on "Have disk" button.
• Now Click on "Browse" button, check out the "Look In" dropdown box and point it to the extracted files, select .inf file, click on "Open" button and click on OK and you are done.
