Hey All,


Just did this cali and was interested in a little feedback.


Thanks.

Looks pretty good... though gamma is a little low and light output could be a little higher (if desired/possible). What pic mode are you using and how did you make these graphs?

 

[poweravguru]

Hi,

Thanks for looking.

I used the THX picture mode.

I thought the gamma was a tad low, but contrast was set at 98 and brightness at 72. I was able to get the number closer to 2.2, but the picture started to look washed out.


I use a Sencore VP401 pattern generator with color pro V sensor. The graphs you see are generated from the 5000a Sencore software.


Thanks again.

Did you set brightness with a pluge or black clipping pattern? It seems quite high (compared to my Panasonic's Cinema mode).

 

[poweravguru]

I used the pluge pattern with the flashing boxes. I normally adjust the brightness until I can just barely see the inside box flashing.

What was your approach for getting a little higher gamma? A higher gamma results in a more 3-D looking picture while a lower gamma results in a more washed-out picture. Your statement is a little confusing.


As far as brightness goes, I think you've set it properly. If you wish to get higher light output, you could make sure ALL-DRV is at FC (the max recommended setting). You could also leave Contrast at 100 (unless this hurts your grayscale tracking).

I seem to remember the gamma increasing as I increased the brightness. I thought the increased brightness produced a washed out image.

Increased brightness washes out the image because it makes blacks gray and lowers gamma. Gamma correction/gamma boost is the inverse of the display's actual gamma value and perhaps that is what you're referring to.

How's the color uniformity? Does this Panny also have the oversaturated greens/reds?

 

[poweravguru]

I did not notice a green/red push. I thought the image looked pretty good overall.


I believe the color uniformity is the same as color error? In the 3rd pdf file, the graph at the bottom is the color error graph.


My understanding of this graph is that you want the line as straight as possible along the D6500 reference point.

You have posted info on gamma, color temp, and peak output. How about pri./sec. color accuracy? I'd also like to know the black level.

Please. This is what I'm most curious about too. And does the G10 offer any sort of CMS in the service menu if you wanted to calibrate the pri/sec color accuracy?

Hey,


I'm a noob with the whole TV calibration thing and just wondering what your actual TV settings were in THX mode? In other words how do I get my TV to the same color accuracy as yours?

Thanks in advance!

None of the Panasonics have a CMS. There are only color/tint controls in both the service and user menus.

 

[lat3ncy]

Well, damn. Thanks for the info though. That would push them over the top in the HT community. They should really do it if they were smart

.

 

[poweravguru]

Please forgive me, but I do not know how to gather this info from the graphs/software that I used.

Without having a CMS, should I be able to measure the color accuracy and the black level?

Yes. A CMS would allow you to fix any color errors, but you should at least be able to measure the color performance as it is. And, yes, black level is critical information.


Not to pick nits, but I also noticed that the dE was reported in xy. That is incorrect. To get a valid dE value the software must first convert dE to Lab or Luv. xy is not perceptually uniform enough to get valid dE figuires.
