Connect Win7 notebook display to iMac I'm looking for a solution to extend my Windows 7 based notebook display to my iMac. The notebook provides the following connectors:

1x VGA

1x Displayport

1x Expresscard/34

I have already tried to connect both computers via Displayport to Thunderbolt adapter but tests showed up that my iMac only supports Thunderbolt to Thunderbolt connections. I have also tried to connect them accross network based software solutions but the notebook firewall which is not under my control prevented this. Any further ideas?
Your iMac can only support TDM using thunderbolt connections, and as such can not be connected to your laptop.
