Setting the EDID operating mode
When a video source is connected to a display, EDID information
is shared between devices, enabling the source to know which
resolution and audio specication the display supports. However,
because this extender can be connected to four dierent displays,
each with potentially dierent EDID information, the best EDID

Up to 70 m (230 ft.) 1080p at 60 Hz

dened.
To maximize compatibility with your displays, this extender features
two dierent EDID modes. Please review the description of each

STD mode (standard)
STD mode congures all EDID settings for a resolution of 1920x1080

ideal for most HD displays, and is the default setting of the extender.

mode is ideal for displays with high resolution support, such as 4K
monitors, or surround sound congurations with 5.1 or 7.1 audio
