Mechanically adjusting convergence
Use the convergence knobs behind the Service door to mechanically adjust convergence.
1. Before adjusting DMD convergence, ensure the projector has reached a steady operational
state. If switching from a white or bright test pattern to a dark convergence test pattern, or if
warming up the projector after a shutdown, allow 15 minutes for stabilization so that the
optics can reach a steady state.
2. Ensure electronic convergence has been reset to zero prior to conducting mechanical
convergence.
3. From the Test Pattern menu, select the RGB-4K-Convergence test pattern and display it full
screen.
4. Open the Service door on the side of the projector.
5. To adjust the convergence knobs, use the 3 mm driver included with the projector.
If adjusting by hand without using the tool, pull out the convergence adjustment knobs to
engage them.
