I did some digging around, found an appopriate cable, and have
hot-plugged a third such monitor into my main desktop now.
Successfully.  There are a total of four DisplayPort outputs on the
T740.  Three on the T640.  I suspect 4 displays would work fine, but
don't have any more room on my desk (or a fourth screen) at this time.
