Why I cannot set
extend mode and
vertical mode with my
desktop/laptop ?
If your desktop/laptop doesn't have the options such
as "Duplicate these displays", "Extend these displays"
or "Portrait (flipped)", it indicates your desktop/laptop
graphic card may be limited or may need to update
the graphics driver. Please contact the desktop/laptop
manufacturers or graphics chip manufacturers for
technical support.
Why my monitor
shows Out of Range?
It means the video source inputted is not in On-Lap's
supported video input formats, and the monitor cannot
display the resolution or the frequency normally. Please
check On-Lap's supported operating modes.
