Black Stripe/Bar(s) Displayed on the Local Port

Certain servers and video resolutions may display on the local port with
small black bars at the edge of the screen.
If this occurs:
1. Try a different resolution, or
2. If using a digital CIM, then change the Display Native Resolution on
the Port Configuration page to another resolution, or
3. If using the HDMI CIM, use the DVI Compatibility Mode.

SUSE/VESA Video Modes
The SuSE X.org configuration tool SaX2 generates video modes using
modeline entries in the X.org configuration file. These video modes do
not correspond exactly with VESA video mode timing (even when a
VESA monitor is selected). The KX III, on the other hand, relies on exact
VESA mode timing for proper synchronization. This disparity can result in
black borders, missing sections of the picture, and noise.
To configure the SUSE video display:
1. The generated configuration file /etc/X11/xorg.conf includes a
Monitor section with an option named UseModes. For example,
UseModes "Modes[0]"
2. Either comment out this line (using #) or delete it completely.
3. Restart the X server.
With this change, the internal video mode timing from the X server is
used and corresponds exactly with the VESA video mode timing,
resulting in the proper video display on the KX III.
