10. How do I enable the energy saving function?
Go to 'My Computer' and select 'Control Panel' followed by 'Monitor Control.' Select "All default
selection' and choose your Philips monitor model from the default driver list. Plug and Play will
automatically enable the EPA tick box for you. In DOS or Windows 3.1, you must first make sure your
PC supports power saving.
11. What is refresh rate?

go into "Start/Settings / Control Pannel / Display / Properties / Setting/Advance/Adaptor" Windows
