Read/Write EDID

I'm looking for software that I can use to:
1) Read EDID information from an HDMI source.
2) Edit the EDID information.
3) Output the updated EDID through the computer's HDMI output.

1 & 2 are pretty straight forward, so I really need something to do 3.

Is there any software out there that can do this?

Hi Colm. I understand that, but I have an EDID capture device (HDMI detective) that I want to write to. I will then use that device to output the newly created EDID.

The device only has HDMI inputs/outputs. I'd like to output an EDID from a computer to emulate a signal that would come from a display that the device could capture.

Unfortunately they don't have utilities that can update their HDMI Detective. I tried using PowerStrip to do this, but I got an error. I mentioned this to Gefen, and I have sent my unit back, and they will upgrade the firmware so that PowerStrip will work.

I've also found another product, in case anyone wants a simpler method of doing this. DR HDMI allows you to read from a source, and also has a utility where you can read/edit/write to the device. Works great.
