I’m sorry that you are having trouble connecting your laptop output. Are you running Ubuntu or some other linux by any chance? There are known EDID issues with Ubuntu and some combinations of hardware.
EDID has worked fine on every PC or device we’ve tried. If you could send a bit more information we will be glad to look into what is happening.
Could you please provide some details about the laptop system:
– Make/model of the machine
– Video hardware and driver used
– OS type and version
