6. After a short operation time the performance of the system decreases
significantly, a blue screen is seen or the system switches off.
a. This issue could occur due to overheating of the system. Therefore
please make sure that there is appropriate cooling around the system. If
the display with KOPS-System is too close to the wall this can cause
insufficient space for appropriate ventilation. Dust build up can also
cause the system to overheat. Thus please ensure there is sufficient
ventilation around the unit, and dust build up has been removed.
7. By using the mini display port no picture is shown / the picture is defective
a. Make sure that the mini display port cable is connected correctly to
the mini display port interface on the KOPS-Sys
tem. Ensure the cable is
connected fully.
b. Please check whether there is any dirt on the cable or on the display
port interface of the KOPS-System. Dirt can be removed with contact
cleaner and a small brush.
8. By using the mini display port the native resolution of the display is not
recognized.
a. Please try and reboot the KOPS-System, to ensure successful EDID
handshaking. Once rebooted, please go into the graphics properties, to
check if the native resolution of the connected monitor can be selected.
b. There could be a restriction of the graphic drivers for your
configuration. Please contact your Kontron support.
