A lot of companies out there use recycled LCD panels so you should becareful. We use brand new, A-Grade panels at Xenarc. And if you get a bad pixel within 30 days and it bothers you, you can always send it back to us for exchange. Our LCD panels are also in general brighter because we upgrade our backlights. We also use better components (such as solid capacitors or Chip Monolithic Ceramic Capacitors) and offer 18 months warranty which is longer than others out there. There is also a difference in Touchscreen panel. Most of our models use 5-Wire Resistive touchscreen panel which is more responsive, has better optical clarity, and last much longer compare to 4-Wire Resistive touchscreen.
