Flicker/Erratic behaviour

  1. Voltage Drop: When there is not enough power running through the pixels to adequately power them. As the voltage travels down the cable from the controller to the first pixel and between each pixel, due to electrical resistance, the voltage constantly decreases. Eventually, it reaches a point where the voltage is no longer sufficient to power the pixel to operate normally. - This will be especially noticeable when the pixels are driven to white (all channels at full). Compare the pixels datasheet to understand the voltage range required with reading from a voltage meter to ensure that the correct Voltage is maintained. Additional power injections can be introduced down the line to reinject the correct voltage or consider reducing cable runs/using thicker cabling to reduce the effects of voltage drop. See our installation tips for further information on power injectors and cabling.
  2. Pixel Protocol: When the pixel controller is set to a protocol that doesn’t match the specification of the pixels. Change the pixel protocol on the pixel controller.
  3. Short Circuit: When the tape/connections could be shorting on each other/ extrusion they are fitted into. Ensure that there is no debris or metal touching the contacts/connections which could cause a short circuit. Test a short separate section of pixel away from the installation.
  4. EMI: When the pixels are installed in an area that has high Electromagnetic Interference, which is commonly found near motors and air conditioning units.
  5. GroundingWhen the installation has connected the pixels GND (0v) or the data line to electrical Earth – This shouldn’t be done!
  6. Network: When multiple sources are sending data to the pixel controller, a flicker can occur if the pixel controller can’t handle HTP/LTP merging or the number of merge sources is exceeded. Run a direct cable from the console/computer source (Art-Net/sACN) to the input of the pixel controller.

  2. Color Ordering: Ensure that the color ordering of the Pixels is matched on either the pixel controller or the console/computer source (Art-Net/sACN) otherwise the orders may be reversed.
  3. Colour Shift on Universe Change: Ensure that the pixel controller is set to be a 3 channel color (RGB/GRB) for pixels which has 3 channel per pixel, or set to be a 4 channel color (RGBW/GRBW) for pixels which has 4 channel per pixel, this is due to the number of channels the pixel controller will output to prevent pixels controls being split between Universes. 3 channel will output 510 channels per Universe, 4 channel will output 512 channels per Universe. If you are controlling 3 channel pixels, ensure that your console/computer source (Art-Net/sACN) breaks to another universe after 510 channels.
