Default what hardware is needed for multiple-screen displays

I just saw an ad for an ASUS monitor showing 9 monitors in a 3x3 matrix
being used to show a picture. It got me curious.

Other than the monitors themselves, what hardware would be needed to do
that? For example, would something like that need 9 graphics cards,
one for each display? Instead, is that done using a specialized card?
Does it require custom software? Does it require high-end CPUs and/or
massive amounts of RAM? Or are there specially made electronic devices
produced to do that?


You could use hardware to present multiple displays (along with software
to split one monitor into multiple virtual monitors). How many
"monitors" a video card supports depends on its driver along with the
the software. The only reason to use hardware is to keep video
performance high for each monitor. If you just want to see multiple
virtual monitors on one real monitor and use one video card to support
them all, just get software, like Dexpot (www.dexpot.de) which is free
for personal use.

I've used Dexpot in the past as a virtual monitor manager. My single
real monitor was not large enough (23") to be showing multiple virtual
monitors; else, each would be rather tiny. I used it to toggle between
different virtual desktops. I'd have one for web surfing, another for
coding, and so one to group together similar program windows. As I
recall, you could have up to 9 virtual desktops, but I only configured
for 4 and even then usually only used 2 or 3.

This is a hardware newsgroup. You never mentioned your operating
system. Dexpot is a Windows program supporting Windows XP, Vista, 7,
and 8.x. Windows 10 is not listed at their site but I suspect it won't
have any problems on that OS. If you are using Windows 10, that OS
already supports virtualized desktops. Might be why they don't bother
listing Windows 10 as supported. Very likely Dexpot supports Windows 10
(but likely with far more features) but virtual desktops is already in
Windows. This is like Microsoft bundling Paint, Wordpad, Defender, and
other apps in their OS but 3rd party solutions are far better. See:
