Be careful. When I looked into those "splitters", I found out
that
<br>
they are closer to "federators". In other words, they take 2
displays
<br>
and make them looks like 1 giant display to the operating
system.
<br>
<br>
So 2 1920x1200 displays would appear to be a single 3840x1200
display.
<br>
<br>
This will give you the number of pixels that you expect, but
your
<br>
desktop environment is unlikely to play all that well with such
a
<br>
configuration.

That's not necessarily a problem.

I had good results with the fakeXinerama library earlier.
<br>
You divert Xorg's Xinerama library with this library, feed it a
text config file, describing what you want,
<br>
and then all X client applications that ask about the monitor
layout (like window managers) get this data.
<br>
<br>
With this, one can make any big monitor appear like several
devices. (And then you can maximize windows to the separated
areas, etc.)
<br>
<br>
Of course you won't be able to use xrandr to configure the layout
of the devices, but if all you want is one constant resolution,
and the devices are placed in the proper order & orientation,
this should not be a problem.

I am more worried about the internals of this "federating"
implementation.
<br>
Do I have to connect identical monitors, or identical resolution
& frequency is enough?
<br>
(For example, would two different Samsung 1920x1200 @ 60 displays
work?)
