[陈伟汉]

Hi all,

I am building a device with a 4k resolution panel

(http://www.panelook.com/T420QVN01.2%20CELL_AUO_42_CELL_overview_23524.html).

My device is running with android 4.4 os.

but in my app to detect the device's resolution , the result is 1920*1080 only.

How to make my build of Android reports the correct resolution to apps ?
