What, exactly, do you see as the differences between the image
on the LCD monitor and what you see on your TV? (In other
words, we're going to need to have some idea of just exactly
why it is you're not happy with this before we can yell you
how to fix it.)
There's no question, though, that a TV image on an LCD monitor
will have a different "look" than that same image on a TV,
especially if we're talking about standard-definition, analog
broadcast television (what we still mean by "TV" better than
90% of the time) and a CRT-based television. The three big
areas of difference will likely be:
- The response time of the LCD is a good deal longer than the
corresponding spec on a CRT. Even though modern LCD
monitors are much better in this regard, and have response
times well suited to video frame rates (and I don't know the
specifics for the monitor you mentioned), the fact that the
LCD is more of a "flash the image up and hold it" sort of
technology makes for a different "look" (more "film-like,"
basically, since cinema projection behaves in a similar manner)
than a conventional CRT.
- The LCD monitor, since it has a pixel format far greater than
what is needed for a standard-definition broadcast, may be
scaling the image from ~480 lines up to whatever is needed to
match the native format of the panel (either that, or it's being
done by the system that's driving the monitor). Either way,
this process can introduce artifacts into the image. (How
objectionable those will be will depend on the type and quality
of the scaling.)
- The color characteristics of the LCD monitor may not be
appropriate for video. The primaries (the colors provided
as the individual "red," "green," and "blue" components) may not
match those assumed by the video standard under which the
TV signal was produced. At the very least, the white point of
the monitor may be off - make sure it's set to the "6500K"
white point (which may also be identified as the "sRGB" setting,
or there may be an overall setting on the monitor's OSD for
"video").
