You will not be able to tell what aperture on your screen as there is no A setting on your aperture ring. Only way to tell your aperture is on the aperture ring on your lens itself
 

Please refer to page 284 of your Pentax K-x Operating Manual and then set Using Aperture Ring to Permitted in the Custom Setting Menu.
Set lens focal length to the focal length of your lens (eg. set 50mm if your lens says 50mm).
