SyncMaster 710N doesn't work with MBA 2013

Hi, I bought DVI to miniDisplay adapter and when I plug it in the screen of MBA goes blue for a second (shows that it connected), but LCD doesn't response. IN Settings SyncMaster is recognised, I can scale resolution and even drag windows to the second screen, but it doesn't show anything. The screen is fine, the adapter too, tried to unplug power cable of LCD, didn't help me. Thank you.
