As was mentioned earlier the monitor has to use circuits such as phase locked loops to discover the horizontal sync frequency. Unlike a lot of situations in which these type of circuits are used, (i.e. digital radio tuner scanning) the time it takes the circuit to lock onto the sync pulses (carrier frequency) is not a primary design constraint.
The likelihood is that they discovered that they could make a monitor which used fewer components and so become cheaper to manufacture at the sole expense of taking longer to sync. As an engineering decision cost wins out so long as the device still conforms to its specifications.

If you are concerned about the discrepancy the best course of action is probably write to the manufacturer and explain why you think the time to sync should be a design constraint.
