You caught me wearing the wrong hat today!

And you make a good point about HIGH QUALITY projectors, which - like the good LCD screens with special hardware - cost a lot of money. Lots and lots of money. Far more money than a JVC HD CRT monitor.

If it's for shooting, how about the latest version of DVrack? I believe they've got an LCD LUT control so you can sort of tune up the laptop's screen to give you a little more of a clue, AND you get a waveform monitor too.

AFAIK CRT's don't have to be interlaced - CRT projectors aren't, are they? Technically I think CRT's need special circuitry to display interlaced images, and there's no reason why they can't scan the whole screen in a single progressive frame.

CRT computer monitors scan in a progrssive fashion, but unfortunately they do not use the right phosphours for TV.

Sure CRTs can be progressive, but their characteristics make them the most suitable type for interlaced display.

BY contrast (ahem excuse the pun) some of the LCD's mentioned in this thread can manage only 350:1 and 700:1. This manifests as burnt out highlights, muddy blacks and a lack of smooth transition between light and dark. However you can check focus and composition on them. It really comes down to whether you intend your final output to be film, in which case I'd go for CRT over LCD every time.

Anyway my $0.02.

I would agree. I'm working on a HD large screen project and needed to view material at at least 720p and wanted 1080p. I considered the Dell and other LCDs but contrast and response times were a real concern. Unfornunately, a CRT that fully resolves 1080p lines and displays it nicely being fed 24fps from AE.is not an option that I've found at any reasonable price if at all (never could find one of the $5K plus HD monitors locally to view.

1080p projecters start at $20k and go up (Sony does have a new "low cost model" at $10k coming in a couple of months.

My "budget" solution was to keep my $600 Calibrated NEC CRT computer monitor, my $500 JVC Broadcast monitor (resolve around 600 lines) and add a Panasonic AE900U LCD projector as my second PC monitor (on a A/B switch to conserve the bulb). Native 720p, amazing contrast that's measured at around 1800:1 but uses faster than frame rate Dynamic Iris to boost to contrast to 5000:1 or so.

Black levels, with the right screen, are very good (not CRT deep) but shadow detail is outstanding. Image looks stunning. Got a projector for $2200 and screen for $500.

Plus you can pick up from the editing bay and drop in the living room for great Home Theater.

A thought to consider in the LCD/CRT debate, put forth by our own DSE, is unless you are shooting for theatrical release, most of the final audience who will see HD footage as HD, be it broadcast or DVD, will be watching on LCD panel or Plasma display TVs rather than CRTs. Thus when colour correcting, etc, what you see when editing and previewing on an LCD panel is going to be closer to what the audience sees than if you used a CRT.

True, but given the great variance in LCD and Plasma panels contrast and color balance I would not rely solely on LCD for CC.

Everyone has a standard
 
I'll stick with the CRTs. Even if a particular users LCD is not in spec, they are trained or familiar with the look and feel of their display as is. Therefore, as long as I stay in spec during post, the view will look the same according to what they are used to seeing. After all, that's why we have a spec in the first place.
