Why doesn't my computer have an option to change the desktop settings?

I know there use to be one, but I can not find it now. It is not listed with the ';display'; options and there is nothing for monitors. How do I fix this?Why doesn't my computer have an option to change the desktop settings?

Open Group Policy (GotoRun and type gpedit.msc).

Then in the laft panel goto -%26gt; User Configuration -%26gt; Administrative Template -%26gt; Control Panel -%26gt; Display

here is place where you'll find the settings to enable or disable the Display setting.
