That math works out.
The key is how much faith you have in getting an LCD with no dead pixels or manufacturing defects (not the same thing apparently, idk why). I have yet to see or hear of Samsung’s having dead pixels and out of 3 Viewsonics I’ve had 1 dead pixel (top right where the red X is anyway) and 2 lazy pixels. Read reviews and see the failure rate before you buy but definately go by Nickname’s list.
