To tilt the monitor backwards, hold the neck of the stand firmly and push the top front of the monitor to the back. To tilt it foward, simply push it at the top back.
I just got my monitor/tv, and the unit doesn't have a tilt feature (and Samsung tech support confirmed this). However, the specs at Samsung.com indicate that it should tilt 20+ degrees, and the CNET video review demonstrates the tilt feature. If you own one of these, does it tilt, or is mine the only one that doesn't?
