It is possible to have multiple X servers running on the same physical hardware, so they get different numbers. For example, I use :0 for high res, and :1 for low res (so the g.f. can read the screen). What these numbers correspond to is like a tcp port number offset, so different applications can talk to the different displays. I think what putty is asking for is :0 or something. Its not worded very well, so its hard for me to say (any PuTTY users out there who use this feature?). What the openssh implementations do for secure X forwarding is on the remote machine, create a listening socket on display :10 (or whatever is availible- this is configurable by the ssh server) and sets the envionmental stuff for it. Then, it forwards any traffic it gets over the encrypted tunnel, and gives it to the local X session via the DISPLAY variable. Since ssh does all the work for you, its a lot easier than working with "xhost +whatever" and specifying displays.
