That's interesting because I just purchased a Wratten 47B blue gel filter to help get the color and hue right on my Sony 14inch flatscreen consumer TV. The first thing I noticed was that the colors now looked washed out, which told me that formerly my color-correction had probably been a little weak.
=========
Actually when I used to do that with consumer TV's (3-4 of them) I got great results, but sometines the videos were a little dark because the "proper" brightness and contrast require both to be turned down considerably which in turn saturates the colors more not less. I used two different setup programs on DVD (Avia and Discwasher) and got the same results with the televisions.

With the monitor I am getting very different results and am wondering if I got a lemon.

Thanks for the response Paul.

Some consumer TVs intentionally boost saturation to make the images look better. So maybe you're used to that??

If there's lots of light in your room, that might affect the picture a little. Broadcast monitors don't go as bright so they are more prone to glare from ambient lighting.

Grazie,

You have one of these (albeit a PAL display). How does the display look to your eyes?

John

John, I have 4 of them in our edit suites and I'm very happy with them.
I also got the 9" as a field monitor.
Grazie bought his on my recommendation.

Mike

Rich - colours are rich. I even pump BBC TV thru to it, they look spectacular. Problem will be, what are you comparing all this to? How do I "monitor" for richness? I do have the S-Video OUT from my Panasonic deck to the S-Video IN on channel "B" on the JVC. Looks kinda good to me? Just looking at some greeny Thames water flow. Lots of dynamic. You think you've got some saturation held back somewhere? Are you comparing your edit deck monitors to the JVC? Have you adjusted all through? Have you got the brightness on the JVC too high?

What can I say? Come over and have a look? .. You are VERY welcome!

Grazie

Silly question, but have you dusted it, or cleaned the glass? I try and keep any direct light off of it. - Can you get JVC to calibrate yours? Then you'd know for sure. G

Thanks guys,
Mike.......how does the image look to you?

Grazie,
Thanks for the offer regarding the webcam. I do know that there are less saturation problems with PAL than with NTSC to begin with so maybe US and UK screen comparisons aren't valid here. Not sure.
It's brand new so dirt is not an issue and I have it hooked up the same way as you do and have input my Sony camera, DV Deck, and a broadcast signal. They all look the same.
The idea about having JVC calibrate it for me is an excellent suggestion. They are right in New Jersey so I think I will do that. Got it for a great price to begin with from G&G (linked above) so if it costs me a little more it is worth it. I don't know how I can accurately adjust the color saturation, gamma, etc if the monitor isn't right. I used to argue the merits of using several television sets to do this on these forums which used to work fine for me, but lots of argument to the contrary finally convinced me to buy this.
I am sure JVC can help me if I bring it in.

John, what I'm seeing on my JVCs looks great. Colours are crisp and clean and no issues with saturation.
I periodically set up the monitors according to Vegas's SMPTE colour bar pattern.
If you're not 100% certain on how to this, here's a great tutorial.

Thanks Mike. I have used that tutorial before. I have not tried the Vegas SMPTE color bar pattern. How are you sending it to the monitor? I am assuming you are also in the UK and are using PAL (judging from the spelling of "colour"). Thanks again

John

That could be part of your problem then. What are you using as a monitor calibration signal?

How are you sending it to the monitor?

Puting it on the timeline and sending it out to the monitor, either through a Canopus ADVC 100 or the JVC miniDV/VHS deck we use.

I am assuming you are also in the UK...

Nope. Canadian using good old NTSC.

I use the color bars generated by my camera. I also use the camera aimed at a Gretag Macbeth Color Checker pattern. Then the AVIA Guide to Home Theatre DVD setup disk. After adjusting the monitor I run a broadcast signal through it to see how it looks and finally a DV tape played through my deck.

Mike,
If you get a chance (whenever you have the time) would you mind posting or sending me all of your calibrated monitor settings. I would like to set them to the same settings just to see how it looks. I realize that mine will probably be different once I have it set up properly, but I would like to try that just to see if you don't mind sending them to me or posting them.

Regards,
John

I use the color bars generated by my camera.

Are you sure the bars are accurate? What's your camera?
I use JVC-550s at the college I work at and I know that I'm getting genuine SMPTE bars from it if I need them.

Then the AVIA Guide to Home Theatre DVD setup disk.

Is the setup level on this test signal at 0 IRE or 7.5? NTSC requires 7.5 for analog signals.

...posting or sending me all of your calibrated monitor settings...

No njeed to. I just use the colour bar tutorial I mentioned above and that's it. I haven't electronically calibrated a monitor in years.
Also, I've been doing this since we switched to colour cameras here in 1979 so maybe that helps :-)

Will try all of the above and if same results will go down to New Jersey and have JVC check the calibration


Thanks to all,

CAn you do a "Camera Snapshot" off of the front of the JVC and have us see the problem. Only a thought . . . .send me a copy - yeah?

===========
I will do that Grazie. I used every suggestion given here and have finakized the settings that match every test including the entire AVIA setup test disk. The settings are :
Contrast + 10
Brightness + 8
Chroma + 20
Phase -8

Seems odd to me especially with the saturation level cranked up that high, but those worked.

I will shoot a still of the screen and post it on Photobucket with a link here. Thanks again Grazie and Mike.

John

Here are three still shots of the screen taken with my VX2000 onto a memory stick. The images were from a DVD freeze frame sent from a disc in the DVD Rom drive on my computer through my DV deck to the monitor. The images were enhanced in Photoshop to look as close to what I am seeing on the monitor although they aren't exact.

Not sure if this is it, but what happens in a monitor is improperly terminated?

At the back of the monitor, there are switches to control termination.

Oh dear John . . that is not correct.

Do you have an option to "lash-up" another monitor - even a box standard TV to view the output. I'm now thinking that maybe what you are seeing on your PC is not what is correct. But tell me? Have you now adjusted, as per the values you posted, and everything is correct now?

Your comments about high sat., had you previously adjusted these settings yourself? I must say I'm a wimp on these things, and I've left them as per the time I removed the monitor from the showroom!

No, the samples aren't good. Great subjects! Great camera work! Hmmm....

Glenn? Monitor termination? What is this?

Grazie

I never use the PC for monitoring video. Have always used a quality Sony TV calibrated using the various methods described above by myself and others and have engaged in past arguments that it was just as good as a "real" monitor. I finally knuckled under to the argument and bought this highly recommended one, but I think I got a lemon.
The settings I started with were the factory default settings and I even reset the monitor to make sure they were actually the default settings.
The adjustments took hours to make and the only settings that passed every test were the ones above yet the colors still don't look right. Very sharp image, but washed out.
It's going to JVC in New Jersey for calibration or repair. G&G won't take it back now. I waited too long to test it (a month).

John

Grazie: The monitor can probably loop-through connections, so you can have a camera feed running through the monitor to a switcher or another monitor. At the end of the signal chain, there needs to be a 75 ohm terminator. Anything else can lead to problems.

Some monitors can terminate connections automatically.

I thought that was only for an RF signal?

Anyway, the monitor is at the JVC factory service center and will be ready in about a week or so.

Thanks again,

John

Follow up:

Got the monitor back from JVC a few days ago.

WOW! What an image!

I can see why you guys like this monitor. The image is pristine and it is a piece of cake to calibrate now. Kudos to you guys for your interest and your help and Kudos to JVC service in New Jersey for the excellent work they did.
