...just one naive question: lcd monitors...

If one uses an LCD monitor, is the preview window "reliable", I mean, will it match a TV set if we make an adjustment by judging by the LCD "reference" ?
If not completely, is there a way to make a series of presets with corrections and apply at preview level?
I ask becuase in my dreams, it would be paradise since ext firewire preview has always been unreliable/nonexistant on my machine (mobo=crap)...
Thanks!

In a word... "No." If you want to get the color right, you'll have to use an NTSC monitor. No doubt, in the not too distant future, your dream will come true, just keep clapping your hands! ;o)

It would seem that the latest trend in studio monitors is to LCD/Plasma. Sony have quite a range of LCD based studio monitors so it would seem there's nothing wrong per see with using LCD monitors for judging color balance. However you'll still need to feed it with an interlaced signal and the only way to do that is via firewire so you're kind of back to square one. Still you do save space and heat. I'd also imagine somewhere in the Sony lineup you'll find a LCD monitor with firewire input. Of course just the option board will most likely buy you a very fancy A/D converter!

That's just for "show" and editing, not color correction. Unless those monitors are NTSC capable, they are not going to give you "broadcast quality" color, if that's what you're looking for.

Having said that, if they are NTSC capable, then you're going to pay very big bucks! If you got 'em, spend 'em! ;o)

I had one and returned it.

The ones we looked at are NTSC / PAL /4:3/16:9 capable and yes they cost BIG bucks. But then again any decent monitor costs big bucks. The next generations ones can adjust the color temp as well by altering the CT of the LCD illumination.
I'd imagine in a few years CRT based monitors will cease production, despite the current higher initial cost of LCD/Plasma total cost of ownership could well be lower as there's far less things to drift meaning less techos needed to keep the things tweaked.

What is the longevity of an LCD screen? I've heard different reports, but most say they won't last as long as CRT sets.

i could be way off here, but i thought LCDs were supposed to last twice as long as a CRT. my LCDs came with 3 year warranty, were most CRTs come with 1 year.

Based on my experience almost all CRT manufactures are giving 3 year warranties on their monitors.

What the warranty is and how long the product actually lasts are two totally different things. I think some people still have TVs decades old that work(granted, not very well, but still alive). Advanced color LCDs haven't been around long enough to know if they'll last that long.

Still, technology progresses forward quickly, and you can't even assume that a decade from now anything will produce a signal that can be used by today's products, so longevity might not be so important.

I just heard an ad wherein Sharp was stating, IN the ad, that their LCD TV would last, using it 4 hours a day, for 30 years or more.

Like I believe THAT!

Both CRTs and LCD use phosphors to produce light (LCDs use cold cathode tubes) and they do wear out. From my experience CRTs do not last that long either. We had over 20 21" precision monitors in service. All had their emission fall below spec within 18 months.
When you are talking studio monitors just because you can get a picture on the screen it doesn't mean it's working!

Keep in mind, back to the original post, that it's not just can you "use" an lcd monitor for the (preview window etc...)
It's the signal for bieng sent to it. (RGB/Svid/composite)
As an example, I have a 16x9 lcd monitor w/ a built in tuner ntsc composite inputs as well. If I were to watch the preview window via the Vegas window the signal is RGB, not even close to what you'll see via ntsc.
Now if I move my Vegas screen over to my other CRT monitor and do an external preview, then switch the lcd to the composite input, thats a better represention of what I'll see on the "T.V. " world.
then again it all depends on the adjustments avail and how well you can calibrate it.
just for the record, my normal setup is
timeline on the lcd(love the wide screen)
small preview window,and various other docks an my 2nd crt monitor
and a 13" tv for external preview.
I experimented once with splitting the external preview to both my LCD's composite input and the tv's comp input at the same time.
The two pic's still looked different even though I calibated them as best as possible (with an AVIA disc).
bottom line, niether are pro monitors with all the nesc adj.
the little 13" gets me to where I need to be for DVD rendering , then I 'll take the disc and play it on my Mit's that been ISF calibrated and readjust if nesc.

which leads me to a question I have, when I win the lottery and buy a nice 30" plasma,..is there a way to go from the firewire out to component video.
I'm sure there is but what box delivers component out?
