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.
