 * 2) Click Advanced, and the click the Monitor tab.
 * 3) Click to clear the Hide modes that this monitor cannot display check box.
 * 4) Click the Adapter tab, and then click List All Modes.
 * 5) Scroll to desired resolution and color depth, click OK, and then click Apply. Click OK, and then click OK again.

Note that your monitor and video adapter determine whether you can change your screen resolution. After you change the desktop area, click Test to determine whether the monitor supports the selected resolution.
