vercal mode with
my desktop/laptop ?
If your desktop/laptop doesn't have the opons such
as "Duplicate these displays", "Extend these dis-
plays" or "Portrait (ipped)", it indicates your desk-
top/laptop graphic card may be limited or may need
to update the graphics driver. Please contact the
desktop/laptop manufacturers or graphics chip man-
ufacturers for technical support.
Why my monitor
shows Out of Range?
It means the video source inpued is not in On-Lap's
supported video input formats, and the monitor can-
not display the resoluon or the frequency normally.
Please check On-Lap's supported operang modes.
