PVM-20L2MD screen position adjustments

[jesgdev]

Anyone here own/have experience with this monitor?  Recently purchased one and it works great, except the picture is off slightly to the left.  There is nothing in the menu for H-position and nothing obvious inside the monitor as far as I can tell.  There are some small knobs, but they are not marked so I dont want to just start turning stuff when I dont know what they do.  Been searching for a service manual for a few hours, but no luck unless I pay for it, which I'd like to avoid since this seems like it should be a simple adjustment.
