Hi, my experience is exclusively related to the DGT USB e-board. Given that my last chessboard arrived with the factory settings and I never had to intervene before to change the sensitivity, it seems that for the PicoWeb image using the 7 "(tested both the 720 and 1080 versions) a sensitivity is required of the chessboard much lower than normal, almost on the verge of the disappearance of some pieces / pawns from the chessboard in order to function without problems. Using the DGT USB e-board with DGTPi or on a Windows platform with software such as Fritz and the Rabbit driver this problem does not occurs. My 2 cents. Luigi
