Display management: Colour depth

  • In the Linux kernel the colour is defined as RGB555 with 16bits per pixel.
    The RFS has the following definitions for display:
    -qt-gfx-vnc \

    Following configurations are made for the display:
    export QWS_SIZE=480X2720
    export QWS_DISPLAY=VNC:LinuxFb

    I find that the display on LCD is proper, but, different section of display on VNC is not visible.
    I tried including the depth in the display settings as shown below, but there was no change.
    export QWS_DEPTH=16

    Why is the display not clear in VNC? What additional settings have to be made to get a proper display on VNC?
