Bought two of them at mouser. Tested with Ubuntu 13. They worked great BUT send them back again because they generat strong high frequency tone. Anybody else with this experience ?

Hi Pici,


The high frequency tone can occur due to the default display brightness of 50%, which is set by the beaglebone black itself and not our display module. This issue can be resolved by increasing the brightness once the 4DCAPE-43 is connected, you can find the instructions on page 4 of its datasheet: http://www.4dsystems.com.au/new/productpages/4DCAPE-43/downloads/4DCAPE-43(T)_datasheet_R_1_5.pdf
