I have had my Sync master 940MW Now for ni on 3 years.
It came with a warranty. a Nice 3 year one.
Any way it is on its way out after 3 years 2 days (according to there technical support)
I have lost its receipt as well.
Phoned Samsung and after chatting to a very nice tech support ..
Its getting replaced
Could not ask for any thing better than that ....
