Color Control System

Color presets selects the desired color setting. The bar is replaced by the color setting choice. Each color setting is adjusted at the factory to the stated Kelvin. If a setting is adjusted, the name of the setting will change from Kelvin to Custom except sRGB mode. Red, Green, Blue: AccuColor Control System decreases or increases the monitor's red, green or blue color guns depending upon which is selected. The change in color will appear on screen and the direction (decrease or increase) will be shown by the bars.

Geometry Controls

The Geometry controls allow you to adjust the curvature or angle of the sides of your display.

In/Out (pincushion): Decreases or increases the curvature of the sides either inward or outward.

Left/Right (pincushion balance): Decreases or increases the curvature of the sides either to the left or right.

Tilt (parallelogram): Decreases or increases the tilt of the sides either to the left or right.

Align (trapezoidal): Decreases or increases the bottom of the screen to be the same as the top.

Rotate (raster rotation): Rotates the entire display clockwise or counterclockwise.

Corner Correction: Allows you to adjust the geometry of the corners of your display Ñ Top, Top Balance, Bottom or Bottom Balance.

Tools 1

Moiré Canceler: MoirŽ is a wavy pattern which can sometimes appear on the screen. The pattern is repetitive and superimposed as rippled images. When running certain applications, the wavy pattern is more evident than in others. To reduce moirŽ, adjust the level by using Ð/+ CONTROL buttons.

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 LINEARITY (VER.) control to adjust the spacing between the lines near the center and

top of your screen.

Convergence: Aligns all three colors (R,G,B) to form a single color (white). The purpose of this control is to ensure that a white line drawn on the screen is as crisp and clear as possible.

¥Use the CONVERGENCE (HOR.) control to adjust the alignment of the lines in the up/down direction.

¥Use the CONVERGENCE (VER.) control to adjust the alignment of the lines in the left/right direction.

¥Use the V-CONVERGENCE-TOP control to adjust the alignment of the top area of the white line in the up/ down direction.

¥Use the V-CONVERGENCE-BOTTOM control to adjust the alignment of the bottom area of the white line in the up/down direciton.
