The 226BW is old and no longer in production. However, it was considered one of the best TN panel monitors back in 2007; if you got the right model.
Model S - Samsung TN panel; considered "Superior"
Model A - AU Optronics TN panel; considered "Average"
Model C - ChiMei TN panel; considered "Crap"
How do you tell the model? It should state it on the box, otherwise you need to rip open the monitor and look for an id tag on the LCD panel itself.
