I've put a physics table in my map, and a monitor on the table. If i remove the table, the monitor is left hanging in mid-air, how do i make it so it behaves realistically?
I think the problem is that i can't place the physics entities on top of the table, i have to put them on the floor and move them into position on the table...so basically they float. I'm guessing this shouldn't happen...
I think your problem could well be that your table (or less likely: your monitor) is not meant as a prop_physics but as static or dynamic. Which may cause strange problems.
Try it with a different table and a different object to put on it.
