Using the viewer window
The viewer window gives you the ability to view and control the CPU IP and its
host computer(s). Its operation is almost identical regardless of whether you
used the VNC viewer or your Web browser to display it.
The menu bar
The viewer window presents a menu bar similar to that shown below. Certain
items within the toolbar are displayed depending upon your access permissions
and/or the CPU IP configuration.

mouse pointer
which you move
and the mouse

are correctly
synchronised.

When using the viewer window
What is the best screen resolution to use?
The best resolution for your computer is one that is larger than the screen of
the host computer that you are viewing. This will allow you to see everything
without scrolling around, as described next.
How do I navigate around a larger screen?
If the screen that you are viewing has a larger resolution than your viewing
window you will need to scroll around to see all items. The viewer window
allows you to ‘bump scroll’ (only in full screen mode). This means that when
your mouse cursor bumps against the edge of the screen, the screen image will
scroll across automatically.
How do I escape from full screen mode?
Press the F8 button. This button is changeable but is most often set to F8.
Why is the
button flashing red?
This happens when a new host screen is viewed (that has not been viewed
before). Click the
button to perform an auto calibration for the screen and
the mouse. See
Auto calibrate
for important information about this feature.
How do I change between host computers?
The best way to change between host computers is to click the ‘Hosts’ button
and then select the required computer by name. See
Host selection
.
How do I remove traces of moved items from the screen?
When you move an item or window across the screen, sometimes it can leave
unsightly trails. These are called
artifacts
and can be particularly prevalent when
the connection speed is low. To remove artifacts, click the ‘Controls’ button and
select the ‘Refresh screen’ option. See
Controls
.
How do I make the most of a slow connection?
The VNC viewer is slightly better suited to slower connections than the browser
viewer because it offers more options. Click the
Options
button of the VNC
viewer when entering the CPU IP address during log on.
Adjust the Threshold setting
Ensure that the video
Threshold setting
is set higher than the automatic setting
suggests. Tweak this setting manually to ensure the best setting.
Fewer colours
Select the
Low (64 colours)
mode. The Very low option offers hardly any
improvement and looks a lot worse.
Rate limit mouse events
When selected, this mode greatly reduces the mouse movement data that are
sent to the host computer. When you move the local mouse, the remote cursor
will catch up roughly once per second.
