Hi,

I am looking for a hardware/software solution to enable a single computer to output display to a matrix of 9/12/16 LCD monitor or TV screens.

Thanx in advance.

raised two clear modes (independent extended desktops per screen, and a single tiled desktop split across the matrix). pointed toward hardware options — useful starting point. Below is a concise, practical summary of modern approaches, what each is good for, and a short checklist to pick the right path.

DisplayPort MST (DP 1.2+) lets a single DP output feed multiple independent displays via daisy‑chain or an MST hub; it is a GPU-driven solution with low latency, but total pixel bandwidth (resolution × refresh) is the limiting factor so check GPU/monitor MST support first. USB-based DisplayLink docks/adapters are another simple route to add many displays without extra video cards; they work across platforms and are great for productivity apps and multiple browser windows, but they use host-side compression and are not ideal for high‑frame‑rate 3D or heavy video playback. (vesa.org)

If the goal is to treat the matrix as one large desktop (tile a single canvas), vendor tiling features and pro video-wall gear are the right tools. AMD Eyefinity can create a single large desktop across multiple panels (note: display groups are per card), while NVIDIA’s Mosaic/enterprise features can present many panels as one logical desktop with bezel correction and sync options. For mission‑critical or commercial walls (perfect sync, mixed inputs, EDID/bezels, genlock), dedicated processors/controllers from video‑wall vendors handle scaling, synchronization and management and are the safer long‑term choice. ()

Quick selection checklist / troubleshooting tips:

  • Define required matrix, per‑screen resolution and refresh first.
  • Decide single large canvas vs independent desktops — that choice narrows solutions quickly.
  • Check GPU/OS/driver limits and whether monitors support DP MST or need docks.
  • For lots of cheap screens: prefer DisplayLink docks or MST hubs and test performance with your real workload.
  • For synchronized/tiled walls: budget for video‑wall controllers or vendor workstation features; test bezel correction and EDID handling before full rollout.
    Start with a small pilot (2–4 screens) using your chosen method, verify driver compatibility and performance, then scale.

do you want each screen to be part of the desktop or each screen to display a duplicate of the desktop?

I want it to work it in following two ways :

1. Each of the screen can be an extended desktop with separate browser instances open in each screen.(this is similar to the way we extend a laptop desktop on the aditional monitor).

2. The display matrix should also be able to display as part of the desktop (the entire desktop view is divided into 9 pieces and each display projecting a blown up piece of desktop.

For this to work you will need multiple versions of a card like this
http://www.newegg.com/Product/Product.aspx?Item=N82E16814195083

Each one of these cards supports up to 4 different monitors so to get 9 or 12 you will need 3 cards, 4 for 16 which would require an extended atx board.

if you want you could also go the nvidia quadro cards.

to display the entire desktop across all the screens leave the cards separate ie. do not put them in crossfire or sli

Hope this helps
