•
Monitor the prism temperature during the convergence adjustment and keep it within a few
degrees of the nominal temperature. Lower the light module power to reduce the temperature.
•
Set the active screen file to 2048 x 1080 no crop to prevent any scaling of your reference
test pattern.
•
Use a 2.5 mm driver with heat-shrink tubing (2.0 inch and 6.5 inch lengths).
Evaluating the convergence
Before completing the convergence adjustment, evaluate the current convergence.
1. Display the DC2K Framing test pattern (on page 87).
2. Turn the zoom adjustment ring on the lens until the entire outer edge of the test pattern frame
fits the screen.
3. Using the horizontal and vertical white lines, check the convergence issues one color at a a
time.
4. Look for twist using the center vertical and horizontal lines—scan from one side of the screen
to the other, observing any change in vertical position of the color in question relative to the
point where you started.
In the following example, red is twisted counterclockwise and blue is high and to the left with
no apparent twist.
