There are far too many makes and models on the market for anyone to be able
to provide that sort of information, but when you do your research for
yourself, it will be helpful to try to get the terminology straight (it's
not easy).
What you term 'real' is probably the mode where the desktop can be spread
across two or more physical displays to give you a single, large, logical
desktop that behaves like it's a single display. This is usually referred
to as the extended desktop mode - the desktop is extended to cover the
display devices. MS also called it DualView, although they seem to have
stopped using this term (becasue it can be more than two). It requires a
display adapter for each display (although in some cases there might be only
one display card, there must always be a display adapter device for each
display) Windows manages the multiple adapters to give the extended desktop
effect.
Laptops have almost always supported an external monitor attachemmnt, for
instance to use when the laptop is being used at a desk. The image from the
inbuilt display is made available at a connector for an external monitor.
This is often referred to as clone mode, however since laptops have been
doing this for years, it is also often referred to as multiple monitor or
similar, and this is where most of the confusion comes from. You will also
see it described simply as 'external montor'. Laptops vary in whether one
or both displays can be active, but in either case there is just the single
image.
Because laptops that support the extended desktop come with the dual display
drivers integrated into the system, they also often support a third mode,
where the multiple display monitors are driven by a single (logical)
adapter, and Windows simply sees one very large screen. The effect is very
similar to the Windows extended desktop mode, but it can circumvent problems
with some applications (such as games) that cannot cope with the extended
desktop. However, it may have some restrictions that extended mode doesn't
have, such as only working properly when the monitors are side-by-side
(Windows extended mode can cope with monitors in any position). This mode
is usually called span or stretched mode.
