Adjusting the Gamma Curve
You can adjust the gamma curve using an exponential
or Bézier function.
Exponential
Exponential sets the gamma curve based on the func-
tion OUTPUT=INPUT
n where n is the number
selected from the spin box. Use the up and down
arrows to increase or decrease n. The following illus-
tration shows what happens when the exponential is
set at 3.2 and the color is blue
Click Update Gamma Curve to display the new curve. The previous curve is dis-
played in gray.
To directly adjust the curve, place 
the cursor over the curve where 
you want to adjust the gamma 
value. The cursor turns into a 
hand:
Click the line. The cursor 
becomes a clenched hand. Drag 
the line up or down to adjust the 
curve and release.

Bézier
Bézier sets the gamma curve based on a mathematical formula that assures conti-
nuity with other Bézier curves. Click Bézier and then click Update Gamma Curve to
view the Bézier adjust screen.
Click and drag the control points to change the curve’s starting and ending points. 
Note: When clicking the Bézier curve control points and end points, the
hand icon turns yellow.
 Click the adjustment points and drag them to adjust the shape of the Bézier curve.

Setting a Gamma Curve Range
You can set a curve range for adjusting the gamma. When adjusting the gamma,
only the defined curve segment is changed.
1. Click the screen where you want to define a region boundary. Do NOT click on
the curve.
The output screen turns gray.
2. Drag the cursor to define the other boundary.
3. Adjust the curve by dragging the adjustment. The adjustment only affects the
line segment defined by the boundary.

Loading a Gamma Curve Configuration
You can load saved gamma curve configurations for editing or sending to the proje-
cor. Click File, Load Gamma Data: Click File, Save Gamma Data. 
Type a name for the gamma data 
file. Files are stored in the

Throw Ratio
About the Throw Ratio
Throw ratio refers to the ratio between the projector’s distance from the screen (or
throw distance) and the diagonal of the image projected on the screen. The following
pages provide throw ratio tables and graphics.
Desktop Installation
The following illustration and tables explain how to calculate the throw ratio for a
desktop configuration. The tables provide values for screen ratios of 16:9 and 4:3.
