Yes, the Samsung SyncMaster S23A750D supports Samsung's proprietary active shutter 3D, but forget about that for a minute. What you should really focus on is its movie and games performance.
Now, not everyone loves glossy screens. As I mentioned before, they can get uber-reflective, particularly during sunny days, and movies or TV shows or games with lots of dark scenes can suffer as a result.
However, the payoff of watching movies on the S23A750D under proper lighting conditions (i.e. at night) is worth any difficulties that sunny days bring.
Check out the full review of the S23A750D as I talk more about reflective screens, dark movies, and yes, 3D.
