The VSEDIDDVI DVI EDID Emulator enables you to capture & retain Extended Display Identification Data from a monitor, which can then be connected to the video signal source (Video Extender, KVM Switch, etc.) to pass the EDID information & ensure the proper video settings are maintained. EDID information contains important display settings such as maximum image size, color characteristics, factory pre-set timings, frequency range limits, etc., & since most video extender systems don′t offer EDID communication between the source & remote display, the DVI EDID Emulator is a perfect workaround for ensuring the optimum signal is provided to the display to help prolong the life of your displays.
