Position of vga pin switch for an amstrad pc 2286 and a monitor pc14cd

[Diego72]

Hello To all, 

It's Diego

I'd like to ask if some one can tell me what kind of problem may be this one of the photo.

A new friend told me could be a problem of misconfiguration of the vga switch on the back of the pc (there are 4 pin).

My pc is an Amstrad pc 2286 and the monitor is a an Amstrad pc14cd.

Hoping someone may help.

Diego
