- Step-by-step fixGet the fix →
After swapping or reinstalling a lens the image is soft, off-center, or shift/zoom acts wrong
Likely cause: Lens shift/zoom/focus are motorized; without calibration the projector uses wrong travel limits, causing soft or mis-positioned images.
- Step-by-step fixGet the fix →
Cannot get full 4K 60Hz over HDMI through the interface board
Likely cause: The board has a fixed maximum pixel-clock; exceeding 4K60 8-bit on HDMI produces no image or a Not Supported message.
- Step-by-step fixGet the fix →
Filter indicator warning / airflow or filter maintenance alert
Likely cause: The Filter indicator tracks airflow through the ACF/filter; a clogged or end-of-life filter cuts cooling and will escalate to a temp fault if ignored.
- Step-by-step fixGet the fix →
Need to update firmware
Likely cause: Firmware fixes signal-handling, network, and stability bugs; using the model-specific package and the correct USB port avoids a bad flash.

No image or intermittent signal dropout over HDBaseT / long cable run
Likely cause: HDBaseT is sensitive to link margin; unshielded cable, couplers, or EMI from power runs cause CRC errors that show as dropouts or black frames.

Stacking or edge blending two units - seams, brightness or color mismatch
Likely cause: Blend seams come from mismatched brightness/color and thermal drift; equal modes plus geometric/edge-blend calibration after warm-up gives a stable match.
- Step-by-step fixGet the fix →
Temp indicator flashing or lit orange / projector overheating or shutting down
Likely cause: The laser engine throttles or trips on over-temp; restricted airflow, a clogged filter, or a stalled fan is the usual cause.
