I found the following on the Internet (google is your friend):
Connecting an Xbox to a PC Monitor
Note - this method is only for playing Xbox on a PC Monitor, but will give
you the best picture quality.
It is possible to connect the Xbox to a VGA display with very very good
results. The key to obtaining good results is to avoid the basic line doubler
devices available from places like Lik Sang. They take the basic 480i signal
from the Xbox and convert it from interlace to progressive scan. This works
but looks very poor.
To get truly great results, you need to tap a quality Xbox signal. By taking
the native 480p, 720p, or 1080i signal from the Xbox and displaying it
directly on the VGA device, you get exceptional results. This is not line
doubling the 480i signal. You must use the direct output from the Xbox or
transcode component to VGA.
There are two devices on the market that do this both very well and
inexpensively. The X2VGA (
http://www.x2vga.com/) is a device that connects
directly to the Xbox and uses the native output to provide a VGA signal. The
VDIGI VD-Z3
(
http://www.vdigi.com/index.php?option=content&task=blogsection&id=4&Itemid=27)
is a component to VGA transcoder. This provides equally great results but
provides the flexibility to use any device that can provide a component video
signal (not just Xbox). This is vastly different than those cheap line
doublers mentioned earlier that accept composite and S-video inputs from any
source. These devices do not transcode and will not provide the same level of
results.
I personally use the VD-Z3 and absolutely love it. You can't really go wrong
with either product.
Using a Laptop as an Xbox Display
Generally, this is NOT possible. The video (S-Video, VGA) connections on
laptops are OUTPUTS. They will not accept an in-bound signal. In order to get
anything on the screen from an external source, you need a Video Input. It
may be possible to connect an external Video Capture device to the laptop and
use an composite or S-Video cable from the Xbox, but these connections are
limited to 480i and the results may not be optimal in any case (i.e. - it may
lag a bit, see below for more details).
