As an off-shoot to this thread

http://www.avsforum.com/avs-vb/showthread.php?t=737550


let's start a new one dealing with actual ColorHCFR calibration issues and discussion. Please post your calibratiion files in this thread to get help or comments from others. The other thread will stay focused on software related issues, revisions and functionality questions.


Try to remember and post your display and set up method so people can compare results on similar setups.

I'll start things off. Here is my original file from day 1 when I started using this great free software. The second file that says final is where I am at to today. I've come along way, but nothing is ever final, right?



This is on a Sony KP-57WS10 rear-projection CRT, using Oppo 970 DVD player and GetGray DVD for test patterns.

I've got a question a the CIE triangle and calibration. From what I've gathered it sounds as though very view displays have any settings to actually change the RGB points. But for the ones that do, what may they be called? For me it would be a service menu item on my Sony KP-57WS510, so what key words may I look for? And I if I understand correctly, the color setting in my user menu will affect the location of RGB on the triangle but this is not really the proper way to move these points.

Hey guys, take a look at my first run & if anyone has any ideas on how to tame my over-saturated color decoder that would be great!!!


Thanks guys!

Carmine.

OK, here's mine.


I'm completely happy with the greyscale and the CIE chart for the most part.


My plasma lets me move the locations of the primaries and I have moved green as much as possible to get it to where it is now.


Next step is to get the red primary moved closer to it's proper location.


I'm also need to try and figure out my gamma at some point.


EDIT: This is for an NEC 61XR4 plasma.

Here is mine..Mits 3000U


Dont forget to put your make and Model guys..so that people know exactly which set your calibrating here..

I have a mitsubishi 57732.


I posted my settings on the other thread before I saw that this was started. I am new to this, so this was my first attempt. Any thoughts on my greyscale measurements?


I am still confused on how to proceed with the primary and secondary color calibrations. Do I adjust the red, green, and blue within the mitsubishi's perfect color setup and then re-measure?

How you adjust your primaries/secondaries will depend on the user interface of your display.


On my plasma it's a very simple and intuitive interface. For each primary you can "move" it's location towards it's two closest secondaries on a slider. This effectively lowers the point of the triangle.


For the secondaries, you can move the slider towards one of the two primaries, essentially moving it along the line of the triangle.

OK, so I futzed around trying to fix my gamma problem and came up with a "solution". I managed to get it to track exactly to the 2.2 curve, along with a very good greyscale, by lowering the contrast a lot. And I mean a lot. It was so low that the PQ was simply unacceptable.


I'll probably do some searching to see if there is any way to fix this on a plasma or whether it's simply something that needs to be lived with.


So, back up when the contrast to an acceptable level and some more fine tuning of greyscale and colour. I think I'm done now because the family unit doesn't want me monopolizing the TV anymore.


Results attached. PQ is fantastic.

JV-


What version of ColorHCFR are you using?? because your gamma is only 1.21..and it looks to be be in extremely (sorry I dont mean to offend) bad shape. What kind of options do you have for GAMMA settings on your set? and what set are you using..

What model plasma do you have? I may be in the market for one soon and having the ability to adjust the primaries would be nice to have.

Answering two posts at once....


richlo, yes, I am using 1.21. After doing some research it appears that plasmas generally work better when you have their gamma set to it's highest value. Mine supports a range from 2.1 to 2.4 and I did my calibrations at 2.2.


Even with the wacky gamme, the picture looks pretty good. As I mentioned earlier when I got my gamma match dead on contrast was so low that it was unwatchable. I've just turned up the gamma on the set to 2.4 and adjusted brightness and contrast again (eyeball) and it looks pretty good. I'll probably do some more measurements / tweaking today. So much for labelling the run "final".



primetimeguy, I have an NEC 61XR4. It's a really, really nice set. NEC and Pioneer share the panel manufacturing (after exchanging some Yen a couple years ago) and the NEC line is for all intents and purposes equivalent to the older Elites from Pioneer.


There's a long thread in the the plasma forum on them.

WHen I opened your file your gamma show its at 1.21 (and thats a loose average) using Camera Gamma, so even lower using the 2nd option..so Im just confused at you stating 2.2.


in fact, if you look at your gamma AVG, Blue line, it looks like a Computer gamma..a straight line from one corner to the other, instead of a curve gamma


Everything else looks phenomenal..

let me know...Ive never calibrated a LCD or a PLASMA for that matter...

The mitsubishi's perfect color setup allows you to change the colors using values 0 - 63. I have a few more questions.


Do I first adjust the primary values and then take a measurements using hcfr?

I am using getgray's dvd, when taking measurments, I set the RGB levels to 0-255, and then used the 75% color windows on the dvd. Is that right?


Thanks for all of the information.

OK, much better now.


Set the plasma gamma to 2.4 and re-adjusted everything.


Now showing 2.1 on the calculated gamma. Solid greyscale and CIE chart as before.


The REALLY final configuration now attached.
