Same monitor and video card, an old nvidia.  I can type ahead as long as 
I wait until the console is almost up.  If I start too soon, some of the 
typing gets lost.  So I usually just wait until it comes up to start 
typing.  There is a noise from the monitor as it syncs in both 
directions, and as you say the synchronization is quick.  About half the 
delay is before the sync click and half after it.
