P2770HD wrong resolution (with laptop)

[Lucky Clover]

Hello guys,
I am trying to connect my asus n53sv laptop with Samsung SyncMaster P2770HD monitor. I created new resolution via Intel Graphics and Media Control Panel (Display > Custom Resolutions tab) because at first I had only 1024x768 in options. But actually when I select 1024x768 monitor says that it is 1280x768 and when I select 1920x1080 it sets to 1680x1050. I have all newest monitor/videocard/intel/nvidia drivers. Any suggestions?

BTW I am using VGA cable. And earlier I used this monitor with my desktop PC and everything was ok.
