2. Setting the resolution
If the output resolution ofthe device is higher than the physical resolution of the
display unit, the display may not display images ; if the output resolution ofthe
device is lower than the physical resolution of the display unit, the image display but
not the best, so we must select identical or similar resolution output .
SWITCHbutton on the remote control switchingthe output resolution ofthe device in
turn, so that the output resolution of device with physical resolution of the display
unit fit that achieve optimal effect, when switching the resolution we must note the
following:
☆Each time you press the SWITCH of remote control, need about 2 seconds before
you can switch to the next resolution;
☆If the output resolution of device is higher than the physical resolution of the
display unit, the display unit will not display images, or display does not support ,and
press theMENU button of remote control does not pop up any menu;
☆After switching resolution, if the display unit can support the resolution, will pop
up enter resolution at side of the screen, you can selected the best resolution that
