Calibrar pantalla 7" TFT Touch Screen LCD - Raspberry Pi Forums

-

hola todos, estoy tratando de calibrar esta pantalla de sainsmart

http://www.sainsmart.com/7-inch-tft-lcd ... a-2av.html

para la rasberry pi 2 model b+ y no encontrado la manera de hacerlo, agradecira alguien que me de un paso paso de como configurar esta pantalla.

gracias.

buenas, yo compré esta: http://goo.gl/b67ibk y si tu problema es de calibrar la resolución, ajusté el overscan en top y bottom -70, sí valor negativo, te recomiendo ir probando valores, para el tema táctil, la mía no lo soporta así que no conozco cómo funciona. saludos. adjunto el config.txt de raspbian.

code: select all
