How to fix BenQ RP551+ when there is no picture?
If there is no picture on your BenQ Whiteboard, check if the display and the signal source device are turned on. Also, ensure all cable connections are firm. If the issue persists, verify that you've selected a supported output resolution on both the computer and any connected DVD or Blu-ray disc player. Refer to Supported input signal resolution on page 63 to select a supported resolution.
Why is my BenQ RP551+ Whiteboard remote control not working?
If the BenQ Whiteboard remote control isn't working, consider these possible causes: the remote control function may be locked (unlock it); the batteries might be dead or incorrectly oriented (check/replace them); you may be too far from the display or at an incorrect angle; there might be an obstruction between the remote and the sensor window; strong lighting may be interfering with the sensor; or nearby devices may be transmitting infrared signals. Ensure the remote is pointed at the display's sensor, and turn off infrared functions on nearby devices.
What to do if BenQ Whiteboard control panel buttons do not work?

Why does the computer input image look strange on my BenQ RP551+ Whiteboard?
If the computer input image looks strange on your BenQ Whiteboard, it may be due to an unsupported output resolution.

You can also use the Auto Adjustment function (See Adjust Screen on page 38) to let the display automatically optimize the image. If the result of the Auto Adjustment function is not satisfactory, use the Clock Frequency, Phase, H. Position and V. Position functions to manually adjust the image.
