Dell S2416DG Gaming Monitor - $400.

No dead pixels, no scratches or marks on the screen or body, still has the plastic cladding on the back and sides so in basically brand new condition. The monitor overclocks to 165hz, and gets very bright. Still has 2 years warranty remaining (Dell gives a 3 year warranty for this monitor).

Retails for $750 direct from Dell. Once you go 165hz you can't go back.

Would prefer pickup from Lower Hutt if possible, but can investigate shipping if needed.
