Sorry guys, I've been browsing many posts but so far i couldn't decide what to buy:
We are a production company doing Ads for TV, shot as follows:
60% on P2, 20& on RedOne, 20% on film.
I'm trying to set the suite up to be able to grade material from all this sources although most 35mm go thru Telecine.
I'm thinking of a serious 24" monitor but can't afford a Grade-1 monitor (20K+€) but 4.000€ or so...
I am doubting between SONY/JVC 24" fullHDs with HD-SDI inputs to be able to work with 1080p.
As i read JVC'd be the winner.
I worked a lot with the 17" Panasonic, quite ok (although it was a bit magenta in the blacks and green in the highlights).
But the 26" model is not true HD and I thought it'd therefore be a bad buy.
What about HP's LP2480zx? Color grading thru DVI is a bit ackward.
I have a Kona 3 for HD-SDI "propper" output...
It looks like who has used it is happy with it...
TVLogic is out of my range but for 7.000€ we could buy it if it was really a reliable and top-notch solution...

Hands down, go with the HP (and a converter like the Gefen). It has the best viewing angle and black level of the two, and it can be hardware calibrated to REC-709 (though I compared it to a calibrated Sony BVM and they were close, but not 100%).
The JVC (if it's the same panel as the V24L1D) has great color reproduction, but the viewing angle is terrible, and blacks are a bit grey (depending on source material). I think the new JVC can be calibrated, though I've not personally worked with it.
There have been countless posts in here about the JVC, and recently a few threads about the HP. Another advantage with the HP is it's truly a 10-bit panel (though will need to take advantage of that through DisplayPort or HDMI 1.3).

That's the thing, i found about both solutions but now it comes the time to confront them.
I just spoke to the TVLogic representative in Spain and the LVM-242W is about the same price as the JVC and sony (4200€).
So I'm thinking about it against the HP (2500€).
You speak bout a Gefen converter... I don't know it, what is it for? (HD-SDI to DVI?).
I worked with HDLink and the result is decent but far from optimal.
With so many issues depending on the Graphic card Color is running on the MacPro i thought the Kona3 would be more reliable...
HD-SDI looked like a more "serious" channel than DVI also.
Maybe I'm wrong and that's why I am seriously considering the HP... Even if it goes 95% of a BVM I'd buy it, it costs 1/10th of a Grade-1!

I've got the HP dreamcolor the other day and it's a really nice panel, BUT the whole 10bit colorspace and rec709 setting ONLY works with RGB-signal via DVI. NOT through HDMI. And since video-colorcorrection is manly a YUV-thing, it won't properly work. yes you can put a converter in between the rgb-output and an yuv sdi output, but i'm wondering if that will be an accucate picture for grading.
the main purpose for this HP monitor is for after-effects, photoshop, and cinema 4d and the likes. where you can see your workspace on the HP computer-monitor in true 10bit. and that's great for 2,5k ;)

You pointed an important issue... Color processes the grades in RGB.
But still the good thing would be viewing them on the final deliver format (YUV)...
I guess I'll stack to the more "conventional" solution, the TVLogic 242W.
Still 1600€ more expensive though!

Russell, i couldn't find a supplier for eCinema in Spain.
I just tested the TVLogic LVM-242W, we were kindly lent a demo unit.
It looks great.
No real black but close and hopefully the ND filter will bring it down as needed. In general the picture quality and detail is pretty nice but there's a big issue which makes me seriously doubt if purchasing it:
A simple Ramp (a black to white gradient across the picture) looks terribly awful: i understant it exhibits stripes (about six pixels each) since it's still not 10 bit...
But each one is obviously colored! One is a bit redish, then bluish, greenish... The gradient is not gray but colorful... horrible.
When it comes to working on real black and white pictures it doesn't exhibit this defect, it looks nice.
A bit of grain on the gradient does obviously solve the problem too.
I tested from both a Kona3 and a Blackmagic HDPro...
Any help is so welcome, I must purchase it asap and overall in real work it performed pretty well.

Guillem, we don't have a signed reseller in Spain yet. However, it sounds like your workflow requires a good true 10-bit solution. None of the products you have mentioned can provide that. eCinema is shipping a true 10-bit 23" monitor priced under 10K in the 1st quarter of 2009, the PRO-2310. Please contact me at sales@ecinemasystems.com if you would like more information.

I understand the gradient isn't perfect since the panel is not 10-bit...
But i'd expect the stripes to be gray, not colored!
I guess the monitor was awfuly calibrated...
¿Or you are telling me this is a normal behaviour with non-10-bit displays?
Respondig to Archie I was really thinking about the HP too, i am looking forward to hear from people using it on a broadcast environment.

Hello,
I've a BM Decklink HD Extreme 2, working with AE CS4, and preview on a JVC DT-24L1D. Connected with an HD-SDI coaxial cable (75 ohm) between card and output screen.
A color gradient is render very bad, like Guillem explain above. Is it normal or I've to configure, or forget to configure something ?
