How can I get my Acer x223w 22in LCD to work with OSX

[ifoundout]

I got the Acer x223w monitor running great on my linux box, but when I bought a second one for a MacBook the resolution is not there. From another post I tried a program called SwitchResX but to no avail.

Any suggestions appreciated.

What do you mean the resolution is not there? Is there no picture?
