I think you'll find it says "Next train to XXXXXX *within* 5 min", so it is
actually correct (though not very helpful, as you say).

Although personally I prefer the (not excessive) inaccuracy of the
Hammersmith display to the the spurious accuracy of those at many other
stations.

What I would really like to see however is the 'next train' information
displayed outside the stations. There are a a few journeys I make where
the choice between modes of transport or between different tube lines
could be effected by the few minutes difference between the train
arrivals. (Admittedly it would only make a few minutes difference so is
probably not worth a lot of money to me and so not worth TfL actually
doing).

and eventually declared. “I understand now. The nose causes the tail”
