My first three (3) 305T monitors had problems right out of the box and my fourth (4th) worked for 8 months and then died. (Please note that all of these monitors were purchased brand new from three different retailers: Amazon, Newegg, B&H Photo).
Monitor #1 didn't work at all.
Summary: I was going to buy the Apple 30" but after reading the reviews I chose the Samsung 30". The first one I received did not work out of the box, I called Samsung they said it was a defective monitor, send back. I returned it back to Amazon and Amazon sent me a new one. The second one doesn't work either. I called Samsung again and again they said it was a defective monitor. Sorry Samgsung I won't be buying your products again.
