help me wall mount my LCD

[vsboxerboy]

So I just bought an OmniMount Cantilever LCD mount, FP CL is the model name because when I went to the OmniMount website and typed in my LCD (Viewsonic N3250W) it showed that mount so I figured that it was compliant. Furthermore, I clicked on the "need an adapter?" link and checked out my monitor. It said that it is VESA 200X400 compliant and that all VESA compliant models will fit without needing an adapter plate. Errr but there isn't any threaded screws on the back of my monitor unless I'm suppousta remove some part or all of the back plastic??? That seemd like a bad idea to me at the time so I haven't done that yet but yeah....I know this is a little vague but any information would greatly be appreciated Thanks!!
