标题: fireflyrk3288 android5.1 點1920x720屏問題請教
平台:fireflyrk3288 android5.1
DLVDS 1920x720屏

剛啟動時ANDROID 跑馬燈顯示正常, 約0.5秒後分辨率自動變成1920x1080
進入android系統後也是1920x1080, 畫面下半部顯示都超出顯示區了

用 adb
查看 wm size    1920x720 正常
查看 cat /sys/class/graphics/fb0/disp_info  , 發現dsp_y:1080 錯誤
請問要如何修改?  謝謝

找到問題點解決了, 感謝各位關注
方法: 進入kernel =>make menuconfig=>device drivers=>graphics support=>
把 rockchip hdmi support, rockchip tv encoder support , firefly vga out/in support都關掉就好了

现在显示正常了吗

理论上firefly vga out/in support关闭即可显示lvds
