Well according to
http://www.compaq.com/athome/showroom/monitors/monitorsasp/mv900/dq/
it has "Easy-To-Use, On-Screen Display Controls", specifically, the
"Horizontal/Vertical Control".
That page doesn't seem to have details on exactly what buttons you
push, but on my Maginnovision, there are buttons on the front
(down/up/enter/menu). You hit "menu", and then select the little
"<-->" icon, and then adjust it farther left. There is also
horizontal size and some others (again, on my monitor).
