| TVLogic LVM-173W LCD Monitor (TV Technology - 1/18/11)
|
|

The
17-inch LCD monitor seems to have become one of the main sweet spots in
HD production. It is—if light enough—reasonably portable for shooters
to use in the field or studio; it is also a reasonable size for use at
an editing desk; and it's a convenient size for individual or small
group client/directorial review.
One
of the newest additions to the 17-inch LCD field is from the
10-year-old company TVLogic, which has rapidly developed and
manufactured a large line of high quality video monitors of all sizes.
FEATURES
The
LVM-173W is a multi-format broadcast monitor, featuring a 17-inch
(diagonal) LCD with a resolution of 1366x768 pixels. It weighs in at
about 15.5 pounds, and is some 3.5 inches thick—inside a plastic case.
Itcomes mounted on a secure, pivoting metal stand for desktop use, and
has a convenient carrying handle on top and mounting points on the back.
The LVM-173W uses a high-quality 12-bit video processing architecture
that yields superior scaling and deinterlacing for image critical
monitoring. The wide range of inputs on the monitor includes HDMI
(standard- and high-definition), DVI-I (RGB), analog (three BNC's that
can carry composite, S-video, or component signals), and two SDI ports,
which can carry 4:4:4 dual link HD-SDI (optionally), HD and SD SDI, and
2K. It is comfortable with all commonly used frame rates (23.98, 24, 25,
29.97, 30, progressive, interlaced, and psf), and PAL and NTSC
standards. Both analog and digital inputs have looping outputs. Audio
inputs are provided for embedded digital (the de-embedder is built-in,
not an optional extra) or mini-plug analog; outputs are a headphone jack
(mini-plug) and tiny internal stereo speakers.
Power
is provided through either the standard AC port (at 100-240 VAC) or via
the four-pin XLR connection (12—24 VDC) on the back of the unit. The
monitor draws about 65 Watts.
Front panel controls are nicely lit
(when activated) push buttons and solid-feeling knobs. These include:
input selection, aspect, markers, over/underscan, H/V sync, blue
only/focus assist, phase/closed captions, waveform/vectorscope, menu,
and then the standard knobs, which include: aperture, brightness,
chroma, contrast, and volume.
Menu controls are extensive and
what you would expect from a high-end, broadcast grade monitor. However,
some of these deserve further highlighting and explication. Waveform
monitor and vectorscope functions are built in and can be displayed
individually, or side-by-side, with a controllable amount of
transparency. The monitor also provides six channels of audio metering,
with information available at various locations and in various
configurations around the screen.
The LVM-173W, properly displays
complex pop-up closed captioning, as well as standard 608/708
captioning. This line of monitors may be the only ones with this
capability built in. The Scan button also offers access to 1:1 pixel
mapping mode—a very useful feature for critical focus checks. A 2:1
magnification mode is also available.
The
entire line of TVLogic monitors provides auto-color calibration using
their optional TVLogic Color Calibration Utility software (MSRP $995),
which works with a range of professional color probes.
IN USE
I
used the LVM -173W both in my studio and on location to great
advantage. In the studio, I connected it to my Media100 edit system,
which features a Kona 3 board for I/O. The colors of the TVLogic monitor
were quite natural, with rich blacks and shadows and smooth gradients.
The field of view was quite wide, and it was easy to see a sharp image
from quite an oblique angle both horizontally and vertically. I was able
to easily get the monitor calibrated, and set up to my preferences and
needs, complete with audio meter and scopes display, along with safe
area. The way in which the menus are set up makes it easy to recall and
dismiss them with a single push of a button.
And
while the built-in speakers are not great, they do function for signal
checking, and it's very handy to have a way to directly monitor embedded
SDI audio without having to spring for an extra (and often expensive)
add-on unit.
In the field, I used the LVM-173W in connection with
a puppet show shoot. The prime requirement was to capture the images of
the show's characters with exquisite detail and to show some subtle
lighting moments. This was challenging, as the theatre was small,
steeply raked, and very crowded. Critical camera focus was key. The
secondary focus monitoring was needed to keep up with the small aperture
adjustments necessary to maintain consistent and accurate exposure. I
was wedged into my position, along with tripod, audio rig, and camera,
and felt like a sardine. However, I was able to hang the monitor beneath
the tripod's legs. This provided a great viewing angle and good
ergonomics for working the camera and checking the monitor display.
The
camera's viewfinder is small and it was a great luxury to have a
17-inch display for focusing. The monitor was accurately viewable, even
from the weird angle that I had rigged it at. In using the LVM-173W as a
reference while shooting, I found—on playback and editing—that my
exposure changes were more accurate and subtle than might have been the
case with just the viewfinder.
During this particular shoot I
powered both camera and monitor with AC, so the 65 Watts of power that
it draws was not an issue. However, this could be a concern when it's
used in connection with battery-powered sessions.
SUMMARY
The
LVM-173W is a top grade, professional monitor in every sense. It's easy
to use and to adjust (even easier when using the auto-calibrate
features), produces an accurate, beautiful picture, and has all the
features needed to function in a studio, edit suite, or as a location
monitor for shooting or review. TVLogic provides monitors in a wide
range of sizes, configurations, and prices. If the 17-inch version is
not appropriate for your needs, odds are that another in the line will
be. The quality and practicality will not disappoint.
