The colors are not
satisfactory.

• Check the color adjustments of the display

or video card.
The colors displayed by different PC
display monitors and video cards will differ
to some degree. Improvement is sometime
possible by adjusting the color settings of
the display monitor. Depending on the
video card, colors can sometimes be
adjusted using Screen Properties (click the
right mouse button on the desktop.)

• Switching to True Color (24-bit) display

Colors are sometimes not natural at the
High Color (16-bit) or lower setting. It is
recommended that you use True Color.

The image size and
position change
spontaneously.

When one VN-A1U unit is connected to
several PCs, the last PC to operate and set
the VN-A1U unit will have priority.

VN-A1U connection is
not possible or the
connection has been
broken.

When there are multiple occurrences of
broadcasts, collisions, etc., or when the
network status is not normal, it may become
impossible to connect the VN-A1U or the
connection may be broken.
