Why is my image grainy and out of focus?
When I turn on my Optoma HD 20 projector, the image appears blurry and out of focus. What can I do to fix this?
The image may be grainy and out of focus because the projector may not be at the recommended viewing distance which is 5.2 - 32.7 ft. Adjusting the zoom lens may also help remedy the problem. If this still isn't fixing the problem you may need to take apart the device and clean the bulb/lens.
