A: No, the light strip is non-cuttable. To maintain high-speed signal integrity and the precision of the RGBIC chips, the strip is factory-calibrated to its specific length. We offer three sizes (9.2ft, 12.5ft, and 16.4ft) to fit different TV ranges. If there is extra length, we recommend using the included clips to create a small loop at the corners. Q2: Will the lights work with the built-in apps on my Smart TV (like Netflix or YouTube)? A: Because the system uses HDMI data extraction, the sync function requires an external HDMI source (such as an Apple TV, Fire Stick, Gaming Console, or Cable Box). Built-in TV apps do not output a signal through the HDMI ports, so they cannot trigger the reactive lighting. Q3: Is this better than a camera-based sync system? A: Our HDMI-based system offers a highly responsive experience compared to camera-based alternatives. Since it reads the digital data directly, it is unaffected by ambient room light or reflections on the screen, resulting in much more accurate and consistent color matching. Troubleshooting: Quick Fix for Lighting Issues Q: What should I do if part of the LED strip isn’t lighting up or colors are out of sync? A: No problem! This is often a simple connection glitch. Here’s how to reset it: Press and hold the "RESET" button on the sync box for 5 seconds (the strip will flash red). Unplug the power adapter from the outlet for 10 seconds. Plug it back in. The lights will perform a white chase effect — this means the reset is complete! Pro Tip: This process helps recalibrate the LEDs and solves most sync issues instantly.
