Extended Display Identification Data (EDID) Support
The IHD-200 PoE series adopts EDID (Extended Display Identification Data) COPY
function to make smooth video distribution over different types of display units. EDID
is greatly important as it contains information about resources’ manufacturer names,
serial numbers, product types, maximum image sizes, color characteristics, factory
pre-set timings, frequency range limits, etc. In some cases, display problems may
occur due to incorrect EDID communication between the display monitor and the
transmitting unit or inappropriate EDID data programmed by display manufactures.
Therefore, with EDID COPY function, the IHD-200 PoE series allows the system to
copy EDID information from EDID compliant displays and assures accurate display
performance.
However, owing to a variety of monitor model types, EDID data may not be usable to
all. For example, if you use an HDMI-to-DVI converter to a REAL DVI monitor, the
copied EDID (DVI) data may NOT be applicable to HDMI monitors. On the other
hand, if using an HDMI-to-DVI converter to a DVI monitor (but in fact it’s an HDMI
monitor with DVI connector), the copied EDID (HDMI) data may be applicable to
HDMI monitors
