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. EDID contains information such as Supported Resolutions, Native Resolution, and Video Formats. Most older cables and most video switches, splitters, or extenders do not support EDID, result is that you often can’t get video from your notebook PC to external display. To easily fix this, Hall Research has designed the EDID Emulator.

It is a tiny device that plugs to the VGA port of your PC and you simply plug the cable to the monitor to this unit. The EM-EDID-HD15 is powered from the PC itself, so in 99.9% of cases you don’t need an external power supply (but if you are connecting to something non-standard that does not provide power on pin 9, we also offer the same device with a small power supply).

We have pre-programmed a lot of standard 4×3 and 16×9 resolutions in to the Emulator, so chances are you will have a perfect video right off the bat. But if you want to specifically program the EDID from a unique LCD into the Emulator, that is possible too with the use of USB-EDID-HD15 (sold separately).
