Also, try to return the monitor to the store or business you bought it from. Their criteria for accepting a return is generally more lax than the manufacturer. Also, if you or a colleague purchase in bulk from the manufacturer (or you know someone that does), it's often easier to get a RMA from them.
On your original note, pixel failure is often a part of the warranty, but generally speaking it must satisfy a variety of criteria as posted by Callandor.
The number of permitted dead pixels is defined in ISO 13406-2 specification.

That depends on each manufacturer, and on whether the dead pixels appear in the center or on the side, and whether they are clustered together. Typically, 8 or more dead pixels will qualify, but you should consult with the manufacturer's policy.
