Frequently, the graphics card in one of your source devices can't read the top resolution supported by an attached display. For example, there may be a KVM
switch in between the source and the display. In that case, it will output video at a default or native resolution that could be lower than what the display is capable of. In a
PC, you could go into the video settings table and change the video output to match the display, if you even know this information. But that's not exactly a plug-and-play solution. This is where the value of a device that supports EDID comes in. EDID provides for optimal source-to-screen performance. EDID will optimize the video card output for the capabilities of the end display. The EDID ghost unit enables the copying, emulating, cloning, and "
learning" of EDID data from a display. The unit works with a variety of devices, such as Blu-ray DVD players, game consoles, HD set-top boxes, LCD displays, and digital
TVs.
