는 아니고  MultiHead 인거네요.

결국 듀얼 모니터를 지원하기는 한다네요.

SNAP이 대단하군요. 우와.

Supported Graphics Chips for MultiHead
--------------------------------------

The following is a list of graphics chipsets that have support for MultiHead
display output.

. ATI Radeon 7000, Radeon 7500, Radeon 8500, Radeon 9000 Series
. ATI Radeon 9100, Radeon 9200 Series, Radeon 9500, Radeon 9500 Pro
. ATI Radeon 9550, Radeon 9600 Series, Radeon 9600 XT, 9700 Pro
. ATI Radeon 9800, Radeon 9800 Pro, Radeon 9800 XT, Radeon X300 Series
. ATI Radeon X550, Radeon X600 Series, FireMV 2200, Radeon X700 Series
. ATI Radeon X800 Series, Radeon X850 Series
. Matrox MGA-G450, MGA-G550
. NVIDIA GeForce4 MX 420, GeForce4 MX 440, GeForce4 MX 440 8X
. NVIDIA GeForce4 MX 460, GeForce4 Ti 4200, GeForce4 Ti 4200 8X
. NVIDIA GeForce4 Ti 4400, GeForce4 Ti 4600, GeForce4 Ti 4800
. NVIDIA GeForce FX 5200, GeForce FX 5500, GeForce FX 5600 Series
. NVIDIA GeForce FX 5700 Series, GeForce PCX 5300, GeForce PCX 5750
. NVIDIA GeForce 6600 Series

Please note that there are some restrictions imposed for MultiHead:

1. Only CRT (15-pin VGA) output is supported for MultiHead at this time.
   You may need to use DVI->VGA connectors on some graphics cards.  The
   only exception to this is the ATI Radeon chipsets, which can also do
   multihead in CRT+DFP configurations, due to native panel programming.
   CRT+LCD, CRT+TV, and DFP+DFP are all unsupported at this time.

2. You cannot use zooming when the desktop is in a MultiHead mode.

3. When the desktop is in a MultiHead mode and you change the MultiHead
   settings, you should reboot before switching away from the desktop
   (i.e. opening any fullscreen sessions), or your desktop will become
   corrupted.  The mouse cursor position may also be incorrect when you
   are running in this in-between state.

4. On Matrox chipsets, hardware mouse cursor and 256 color modes will not
   be available; these are hardware restrictions.

5. On older Nvidia chipsets, 16M color modes wider than 2040 will not be
   available; this is a restriction of the NV1 interface.  Only cards
   where the video BIOS properly initializes both heads (in other words,
   it boots in clone mode automatically) are supported.

I would certainly opt for the Matrox boards. These are still available (new, 3 year carry-in warranty) and offer the best 2D performance for eCS:
