Quick summary and what works: an “extended” dual-screen (independent desktops where the mouse crosses from one monitor to the other) requires two independent video outputs from the PC (two ports on one card, two cards, or an active adapter/dock that provides an extra display output). A passive VGA/HDMI “Y” or splitter only copies (mirrors) the same signal to both monitors — it cannot create two independent displays. was right to flag that games and apps behave differently on multi‑monitor setups; many titles do not render separate viewpoints unless they explicitly support spanning or surround modes. (support.microsoft.com)

How to read the hardware and connectors: older integrated chips such as Intel’s 82845G family usually support up to two displays, but whether both ports are enabled depends on the motherboard design, BIOS and drivers — check the chipset/motherboard documentation before buying an extra card. Identify ports by shape, not color: a VGA DE‑15 (3 rows of 5 pins) is very different from a rectangular DVI or the flat HDMI/DisplayPort plugs; color coding is not standardized. For some adapter combinations (DisplayPort -> DVI/HDMI, or using MST hubs) an active adapter is required. (alldatasheet.com)

Practical setup checklist (typical flow):

  1. Confirm how many physical video outputs the PC actually has.
  2. Get matching cables/adapters for those ports (DVI‑I to VGA is passive; DP->HDMI sometimes needs active).
  3. Install/update the latest graphics drivers.
  4. Connect monitors, power them on, open Display Settings (or press Win+P) and choose “Extend these displays”; use Identify/Detect if a monitor is missing.
  5. If the PC has only one output, use a dock/USB video adapter or fit a second graphics card. (support.microsoft.com)

Gaming note and final cautions: stretching a game across two screens is different from having “different views” — only certain sims and titles support multi‑camera or bezel‑correct spanning, and spanning increases the total pixels the GPU must render (lower FPS). For widescreen/surround gaming look at vendor surround/eyefinity tools and the game’s compatibility list before buying multiple monitors. Also avoid forcing passive splitters if the goal is an extended desktop — they will just mirror the display. and raised the right options and limits earlier; the above steps show the safer, more reliable approaches.

This should answer your questions

For the multiple view points, I believe this is only possible if the game supports it (and I think it's limited to certain flight simulators).

The only video card I've ever seen do anything similar to that is the Matrox Parhelia line, and they're WAY expensive ($500 US for a 256MB tri-output card). They're meant to span 3d modelling apps across two screens, but that doesn't mean you couldn't frag with 'em...

Zoicks! Support is more widespread than I imagined. A pity the Parhelias are not the best for gaming. :-|
