Linearity: This selection allows you to adjust the spacing of the area on the screen. The purpose of this control is to ensure that a one-inch circle is a true one-inch circle wherever it is on the screen. The best way to determine the vertical linearity is as follows:

•Draw equally spaced horizontal lines using a drawing application that has a ruler.

•Use the Vertical Balance control to adjust the lines near the top and bottom of your screen.

•Use the Vertical control to adjust the spacing between the lines near the center and top of your screen.

GlobalSync® Control: Eliminates picture impurities that may result from the earth’s magnetic field. While in the sub-menus (GlobalSync, Top Left, Top Right, Bottom Left or Bottom Right), use the –/+ control buttons to fine tune the GlobalSync corrections.

Note: NEC recommends that you perform GlobalSync correction while running a typical application such as a spreadsheet or text document.

Sharpness: Allows you to adjust the clarity of the image, based on the quality of the signal received from the computer.

•Use a full text document to make this adjustment.

•Cycle through the four sharpness settings and select the one that provides the sharpest focus and contrast of the text.

Factory Preset: Selecting Factory Preset allows you a reset most OSM™ control settings back to the factory settings. A warning statement will appear to confirm that you do want to reset ALL settings. Individual settings can be reset by high- lighting the control to be reset and pressing the RESET button.
