I have been running three of these and they are gorgeous! I'm being forced to move to Mac by my work and so these are no longer needed.
They are fantastic screens, the colors and contrast are great and they are amongst the best reviewed on Amazon - http://www.amazon.com/Dell-927M9-IPS-LED-27-Inch-LED-lit-Monitor/dp/B009H0XQPA . The only downside is that they are glossy so if you have a window directly behind you then they might not suit.
Happy to sell 1, 2 or 3 at once. I'm based in Darfield for pickup or can meet in Christchurch area, not looking to post as I don't have the original boxes, only the screens themselves and the bases and power units.
They were set up on my desk and haven't moved since so no dings or scratches and still sell for $450-500 -http://www.elive.co.nz/dell-s2740l-27inch-ips-monitor-AC03074.php
Looking for $295 for one, open to offers if anyone wants 2 or 3.
