Some computers will get a message saying that the computer will need to re-boot for changes to take effect, but most people will see the message "Apply changes without re-starting?", click YES.
Once the change takes effect, you will be asked wether or not to save these changes. If the screen looks OK, then click YES. ( you have 15 seconds to accept the new settings)
If the screen is distorted or unreadable, do nothing. After 15 seconds, it will change back to your old settings.
