Panasonic VT50 Self Vs. Pro Calibration - Page 7

2.4 did not work for me ever. What is so terrible about your autocal screen shot? The dE looks lower than 3 to me. I tried targets 0, 0.4, and 0.5. All got the dE really low. What are you using?

What was the fix for the i1pro2???????


Have you had a chance to take a look at 3d calibration?? Thoughts??

Actually, not only for the i1pro 2 but for the I1display (D3). I guess the fix is for better comparability with Calman.
Don't know if it works or not, I will be trying out my i1pro 2 with the b395 software tomorrow night.

No I haven't done anything with 3D yet, Jeff (UMR) is going to be stopping by my house next month to help me out with 3D. But mainly for the light reading with his Photo Research PR-670.

Getting the dE low is not a problem, the problem is not using green to get there. Plus the fact that autocal does not calibrate are CMS, nor set the light level (contrast).

Yes using the settings I did is a bit unfair, however I can get good (not great) results when I do my calibrations manually with those settings. As far as the dE targets go I used the default, what ever that is. I normally use a setting of 0.

That said, your charts look good but without seeing the numbers I really can not say for sure if your calibration is good or not so good.

Anyway you are off to a good start.

You can autocal the CMS. I spoke with someone at Spectracal in April or May, and they told me that they removed or hid the Autocal for CMS because it did not work as well as they wanted it to. They also said they were working on it and would add it in later in the year. I know how to add it back in. I have used it in the past and it did not yield good results because of the inoperable luminance controls at the time. Autocal CMS works really good now. You have to add your own action button and set the command to do DisplayAction.SetAllGamut. See the screenshot below.

Turbe,

Anything new to report on this? Is SpectraCal satisfied that all issues have been resolved with the new release or is SpectraCal still working with Panasonic on this?

Thanks

Yes, I updated my post above the one you quoted..

Not exactly as I originally posted (though there was one report for that), but from Calibrator reports including from Kevin Miller who has already posted, it's best to not update unless you can get a recal.

8/4/2012 Update: For those who have had their displays professionally calibrated already, it is recommended that you do not update to v1.150 and you contact your Calibrator.

Also on these models, there is size and unit to unit variation including with common builds in regards to performance with the update..

The Calibrators who have already provided feedback to me for post v1.150 indicate that this is a recommended f/w update

The bottom line, you will want this update so schedule a recal... it is also being pushed down the pipeline by Panasonic.

Thanks for the tip.

I think you can also use Standard Interactive mode to access both Gamut and Grayscale, and let autocal do the work. Simply drag and drop what ever you are working on.

I tried the interactive stuff before. IMO doing the autocal works better and it will save you time. Especially when doing the grayscale.

are these VT50s that hard to calibrate manually that spending hundreds on auto-cal is worthwhile? just curious

With the new firmware I was able to get a good calibration (using ControlCal) in about 3 hours.

that's not too bad, especially given all the picture controls this set has

I get it; it's not required, but might be cool to have.

I just noticed something weird with the IRE Gain controls in the Gamma Detail Adjustment menu. I am using Calman 4 and when I change the gain for ISF DAY it also changes for ISF NIGHT. So both my night and day settings will have the same gain value. Can anyone who uses Calman 4 test this? All the other IRE controls are specific to their ISF mode except the Gain. This is the same as the IRE luminance if you are using the DDC workflow.

I got around this by using ControlCal. Thanks Turbe!

Hi,

I don't know whether this is the right thread but I'll try anyway, because the most knowledgable ppl seem to lurk here...

I'm looking into getting the European VT50 for domestic as well as studio use as a preview/grading monitor...I'm more or less aware that I can expect fairly accurate rec709 picture from the THX mode...(APL issues aside for accurate black level monitoring, still undecided whether it's a deal breaker)

however, I learned that this TV has the possibilty of a wider gamut operation, i.e. the wide gamut option (color remaster in the european version) unlocks the gamut simulation i.e. the TV is allowed to use the full gamut of its phosphors...

does anyone know what colorspace is it closest to i.e. which wide colorspaces fall inside it: P3, AdobeRGB, xvYCC...? I was hoping to perhaps use it to grade the shorts I produce on it, for P3 digital cinema projection (would require to be shot in wider colorspace, of course, say xvYCC or professional cameras like RED)...I also rely on the "pure direct" mode to get 4:4:4 chroma resolution, will it work in wide gamut mode? also will the VT50 accept and work with true 10-bit input from the graphics card?

Thanks...

Just from production variances, it won't be that accurate.

For your application, you'll need to be sure that it's frequently recalibrated.

Thank you...

the idea was not to have absolutely accurate display but one that I can trust is close to reference from the factory without the of need for calibration (I don't have a client to rub my nose in it )...

however I confirmed myself that ABL and 50 Hz bug are present and am slowly steering away from VT50, albeit not completely yet...

As a Silver Premier customer at Best buy I am entitled to free calibration through geek squad.
