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 Amanda bluehash and spirilis 2 Quote Link to post Share on other sites
pici 0 Posted October 4, 2013 Share Posted October 4, 2013 Hi Amanda, ok it works - but only with 100%. When i dim down to 80% it's noisy. Regards Pici Quote Link to post Share on other sites
