Don't know about a DECmate, but if you did that with a PRO, you'd
probably run into a selftest failure due to missing keyboard. If so,
you'd probably still get at least a display on the screen, or perhaps
some selftest status LEDs on the back of the box changing from their
powerup default (which should be "all on" if the DECmate follows DEC
convention).

So you don't have to go dig, the video pins are:

4 -- mono return (common)
5, 6 -- ground
12 -- mono video
13 -- monitor present L (i.e., ground this pin)

The full description is in the Pro technical manual, volume 1; I took
the above from page 5-130.
