The VSEDIDDVI DVI EDID Emulator enables you to capture and 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 and 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., and since most video extender systems don''t offer EDID communication between the source and 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. This product is TAA compliant and backed by a Startech.com 3-year warranty with free lifetime technical support.
