How do we connect multiple monitors (upto 8) to a single computer

Hi,
I have seen people in financial markets are working
simultaneously with about 6-8 monitors. My question is how do they do
that? is there are special hardware to support such number of
monitors.

Thanks,

DJD

Six monitors is easy, there are several motherboards with three PCI-e
slots.

Technically if your 1-lane or 4-lane slots are open-ended then you could
install more, the cards just wouldn't perform well -- No problem for
Windows and apps, but it wouldn't game well.

Matrox Millenium G450 is a quad-head DVI-out PCI card, ATI FireMV 2400
Video Card is a quad-head DVI-out PCI-E card.

Two of either of those in a regular 'ol motherboard would be eight
monitors, three in one of the new triple 8x/16x/whatever PCI-e connector
motherboards would be 12 heads.

Another way to do it, is a video card with two connectors on the faceplate,
plus a couple Matrox DualHead2Go or TripleHead2Go adapters. Those
two devices, take a single video output, like 3840x1024 and make
three 1280x1024 display signals from it. Each monitor has a fixed
relationship to the other ones plugged into the Matrox device.
Matrox.com has a web page that gives details about supported
configurations. This is not as flexible as using multiple
video cards, but may have better performance. It might be
an option you'd use, if the motherboard only had one good
slot on it for a video card.

Examples here.

There is also a site that specializes in multi-monitor setups. Click the
"Gallery Home" button at the top, and review all the different systems people
have put together. The main reason for browsing here, is to get some idea
as to whether there are problems mixing drivers for the various cards.
Some entries in the gallery, give details or hints about order of
installation, or stuff that didn't work.

A number of the trading floors use SunRays. They're tiny thin
client units about the size of an external disk drive, each of
which drive up to 2 screens, as well as handling keyboard, mouse,
etc. They are also used for building large video walls out of
many screens. They connect to a computer over ethernet, which
means the computers are all in a data center elsewhere in the
building or thousands of miles away, rather than loads of PC's
littering the floor area, which would be expensive to maintain.
