Can I use flat-screen video as computer monitor?

I'd like to have a TV in my office, and found a 20" LCD product badged
"Vizio L20" for $200 -- with 640 x 480 resolution, compatible with
480i/p, 720p and 1080i signals.

It accepts VGA, A/V, S-video, and composite video inputs. I'd like to
use it as a conventional off-air television set, but would also like to
use the S-video output from my laptop to drive it as a large monitor
that clients can view.... Is this practical? Will it be visually okay?

Also, my area has a lot of HD broadcast signals. How can I view them on
that display?

Thanks, gurus!

  With the VGA connection, it should be usable, but obviously low
resolution. Every monitor is different, so you won't really know until
you try.

  640x480 is not HD, it is ED (Extended Definition) when 480p or higher
is supported. You don't mention if it has component inputs, typically
colored red/green/blue, unless that is the A/V you mention. Without that
or DVI/HDMI, you cannot feed it an HD signal anyways. Composite and S-
video only support 480i. I'm not certain if you can properly feed an HD
signal through the VGA port.

  Otherwise, to view HD, you would need an external tuner. Either
something standalone like a satellite, cable, or off-the-air tuner, or
something through your computer.

hl,

I have been researching this lcd tv as well. I have found it online as
low as $299 and would be interested to know where it can be found for
$200.

Over on epinions.com, there are several reviews for the vizio l6 lcd
tv, whose specifications carry a lot of similarity to the l20. Other
than the case color, they appear to be the same. Anyway, the consensus
of the consumer reviews there are that the set has good picture
quality, but is slow to refresh the display when changing channels
using the set's tuner. There are also some complaints that the on
screen menu's for setup, etc. are difficult to use. Other than that,
the reviews seemed to think it was a good value for the money.

Having read those reviews, and with the Vizio at a price point of $300,
I was considering a $400 Viewsonic N2000 model instead. However, at
$200, I think I could overlook the Vizio's flaws.

The Vizio set has vga, composite, s-video, and component inputs, and is
also cable tv ready with a coaxial input. So, as Andrew said, this set
is capable of displaying a 480p EDTV signal via the component input.

Using the VGA input you could also use the set as a 640 x 480 external
monitor. As a computer monitor that's going to be very small. If having
a lcd tv that also doubles as a extra pc monitor is an important
feature, you might consider the Samsung 930MP. It's a 19" lcd tv set,
that when used as a monitor supports up to a 1280 x 1024 resolution.

Vizio's website (http://www.vinc.com) no longer has information on this
set. However, the pdf manual for the L20 can be found and viewed in
google's cache, by searching with the terms "vizio l20 manual".

Cheers,
Jonathan

The $200 price was through a military exchange retail store - I'm sure
it's not available in the U.S.

THANKS for the guidance.
