Depends on how loud you complain to NEC they may fix/swap it for you. 1 dead pixel is considered within spec so they may not fix it. However, since it's for HT and if it's in center and distracting, they may. Best bet is to call NEC cust. service and ask. Forget Dell as they won't swap it for sure. Dell cust. service is pretty long-winded and worthless, IMHO.
