VT30 series and it's calibration

[Panny65vt30]

I will be getting my VT calibrated when it has 500-600 hrs on it .
Untill then David's calibration  settings would be great but they are not on Facebook yet !

[Panny65vt30]

Would I be correct in thinking that THX and PRO1-2 are the same in respect of grey scale and colour ect ?
THX is clearly brighter then Pro modes but when I drop the brightness in THX and flick between THX and PRO 1 , I see no difference in picture quality .
From what I have read in reviews on my 65VT50 the green is the problem colour and to correct this I should increase the red and blue in the 2 point white balance adjustment ?
I'm just trying to get the best picture possible untill I get My VT pro calibrated in 500-600 hrs of running time .
Is it possible for a pro calibrator To calibrate THX mode as I don't FBr in this mode but i do see it in PRO 1-2
But only on my 65" my 50" has no FBr at all

[David Mackenzie]

Yes, they're basically the same in terms of Greyscale and Colour.

Is it possible for a pro calibrator To calibrate THX mode as I don't FBr in this mode but i do see it in PRO 1-2

Yes, they can calibrate Greyscale in the service menu. But not Gamma.

If you have FBR issues, make sure you're running the latest firmware - it solves almost all of it.

That's great  to know david as i think the gamma is spot on since the last fw update .
As for the FBr im Running 1.604 which is latest FW for 65"
I installed  the leaked 1.520 last year on my 50VT30 and that worked a treat , so  i asumed it was fixed  now on all models ! 
I see FBr in game mode when playing cod and in pro1-2 when watching tv , I have not seen it in THX as yet fingers crossed I never will .
I will find some Blu ray films that show it off well and post titles and time frames .
In the USA there are saying FW alone is not fixing FBr on the bigger sets but software upgrade on the A board is working
I don't know if I should of waited for the 65VT50 now  .

Hey guys

I had my 65VT50B calibrated yesterday by a THX approved calibrator in the UK.
The 3D has improved 30% to my eyes and im very happy with that but the 2D is just not looking right to me !
Faces  look like a slapped ass in dark scenes and sun burnt patches on cheers and forehead in normal brightness scenes .
This is in pro 1 with 20FL for night mode.
THX modes does not suffer from the problem.
At the end of the calibration the guy achieved perfect gamma , errors less than one for greyscale and colours also less than one in errors across the board .
Could any calibrators out there with any explanation for my problem please help !!!!
I have spoken to the calibrator today about my problem he suggested lowering red Lum. Or drop colour a click or two.
Red Lum did not help but dropping colour three clicks did help but in doing this was there any point in paying for a pro calibration ?

I would have thought any Calibrator worth his salt would have returned to you if you were not happy, Fuel costs may have come into it yes but to advise you to change settings willy nilly is not very proffesional in my eyes  .

We had this problem when the 10-point Gamma correction was used. An example we used was on the NHK World news, reflections on balding newscasters' heads (sorry NHK!) appeared slightly "burned".

At the end of the calibration the guy achieved perfect gamma , errors less than one for greyscale and colours also less than one in errors across the board .

The trouble is that with the Panasonic displays, the gamma performance varies depending on APL. It's possible to align things perfectly with test patterns, but the real world usage can and will differ.

In the end we managed to get around the problem by calibrating Gamma and Greyscale using APL patterns, which take into the account the approximation.

My suggestion would be to note down all the calibrated settings for 10-point Gamma, and then return these to 0 and see if the problem goes away. Keeping in mind that you will not achieve broadcast-monitor quality perfection on any current consumer TVs, anyway.

[Panny65vt30]

Thanks for your input David i will give that a try
The calibrator that did my VT is coming out again next week to see what we can do fix the problems

[Panny65vt30]

I just reset all 10 point gamma and it looks to have cleared up the issue :-)
How did you get correct gamma without 10 point gamma control use ?

[David Mackenzie]

We did use the 10 point control, but we calibrated with APL patterns (from the free AVSHD 709 test disc) and constantly checked to make sure it wasn't doing anything damaging. When your calibrator comes back, ask him to try this out.

[Panny65vt30]

Well do thanks again

Did he used 10 point gama control? If yes, then this should be main reason for this. As I found myself, as also was noted by AVforum reviewers, touching 10 point gama controls introduces errors in overall image . Due to this, I use only white balance controls.

[Panny65vt30]

Yep when I reset 10 point gamma the problem went 

[Panny65vt30]

Well my calibrator returned to recalibrate my 65VT30 today
He did a complete recalibration of pro 2 with APL patterns this time and the end result is perfect :-)
No sunburnt patches and an improvement in details in blacks .
In the past I have used calibrated settings from forum post's thinking it was an improvement
But now I can see these settings were way off .
I have tried 4 different calibration settings from different sites and they have all been completely different.
In the forum post's guys have said there calibrated TV's look amazing after a pro calibation and i would ask what %  improvement would they said thay had over out of box settings ,  No one could really say
Well I can say this    15% improvement on 2 D.  And 25 % up on 3D  on out of box settings .
I had read that  not pro calibrating a top end Tv is like buying a Ferrari and puting bold tires on it !
I can see that is so true now .
I paid £3300 for my 65VT30 so £225 for a pro calibration is a no brainer .

Glad to hear you got it sorted and the calibrator had success with APL.
