Most PC's and Notebook require a special handshake from the LCD or display device before they output video. This handshake involves reading the EDID table from the monitor.
The EDID contains information such as Native or supported resolutions and Video Formats. Some older equipment may not support the EDID properly and the end result is that you often can't get video from your PC to external display.
To easily fix this, Hall Research has designed the EDID Emulator. It is a tiny device that plugs to the HDMI port on your source device and you simply plug the cable from the monitor to this unit. The EM-HD-NCP is powered from the source itself.
We have preprogrammed many standard resolutions into the emulator, so chances are you will have a perfect video right off the bat. But if you need to specifically program the EDID from a unique LCD into the Emulator, that is possible too with the use of USB-EDID-PRO2(sold separately).
