Troubleshooting Tips and Best Practices
Video Does Not Appear on Display Device
The following situations might cause the display device to remain blank (black) or display something
other than the video you expect to view; this section does NOT describe situations where the “No Video”
message appears on the display device.
Power Not Supplied to vDisplay IP Engine
Your display device might appear blank or black if power is not supplied to the vDisplay IP engine. Check
to see that the small LED light, located just below the power connector on the vDisplay IP engine, is lit
in either green or orange. If it is not lit, verify that the power cable is connected properly and that at least
12 volts of power are being provided. When the LED is lit, the power cable is functioning properly and
providing power to the vDisplay IP engine; in this case, you should try to connect to the vDisplay IP
engine using GEVPlayer.
vDisplay Unable to Retrieve EDID Information From Display Device
Your display device might appear blank or black if the vDisplay IP engine is unable to retrieve the EDID
information from the display device. If you are able to use GEVPlayer to connect to the vDisplay IP
engine, connect to the vDisplay IP engine and in the
Status
section of the
GEV Device Control
dialog
box, check to see that the vDisplay IP engine successfully retrieved the EDID information from the
display device. If the EDID information has been successfully retrieved,
EDIDStructureSupported
is
True
. If this status is
False
, you can enter the display device parameters in the
DisplayTimingControl
section of the
GEV Device Control
dialog box. For more information about display formats, see
