Can not connect mac mini to a 17inch screen I am trying to connect my mac mini MD387D/A to a 17 inch Samsung screen Sync Master 730 which has around 9 years and supports up to 1280*1024. 

I have a VGA adapter from my mac mini which worked before with two other screens of 24 and 27 inches. 

The monitor behaves as follows: when I start my mac mini, the apple starting screen appears with the apple in the middle and the load icon beneath it, after a couple of second, the monitor goes black and says that there is no signal. 

Could someone guide me towards a solution, or do I need a new monitor? 

EDIT: I found this specs that says: Screen Resolution  1920x1200 does this imply that it is what I should at least have?
There are few places you need to look


About this Mac-> displays (to see if it shows there under correct name)
In sys pref ->displays- does it show there as correct monitor


Select Mirroring in here

A console report from the time stamp when you plug it in
