Re: dual monitors on a laptop

 DVI is the de-facto standard for HD (high definition) TV. VGA/SVGA/XVGA are

It's common when editing video to put the preview video on an external
monitor while the video editor's timeline and control windows are displayed
on the native VGA/SVGA/XVGA display.  To do this you need both an
appropriate video editor (Sony Vegas supports this "split output") and an
appropriate graphics card. The high-end Nvidi Geforce graphic cards have
supported twin outputs (15-pin XVGA and DVI) for at more than five years.
The Dell Inspiron XPS M1710 comes with either 256MB or 512MB nVidia Geforce
7900 GTX Graphics Card giving a DVI display of up to 1920 x 1200 with 16
million colours. The 512MB variant is best if dual displays are required -
for obvious reasons.

I'm a little surprised that Dell haven't targeted the XPS M1710 towards
transportable video editing - but I suppose it's because the "gaming"
community is far larger.

Actually, DVI is disappearing from the HDTV scene, replaced by HDMI.
However, the electrical signals in DVI and HDMI are identical.  HDMI
simply uses a different connector (a VERY different, much smaller
connector) and includesd additional pins for the audio and video to both
be carried and connected in a single cable/connector.  Because the
signals are the same, you can get HDMI to DVI converters (both ways) and
cables with a DVI connector at one end and an HDMI connector at the
other end. wrote:

Dell have the Precision M90, which is virtually identical to the M1710, but
sold as a mobile workstation rather than gaming system. It has Quadro rather
than GeForce graphics, but as far as I'm aware, the difference between these
is in marketing and support rather than in hardware.
