Controlcal g/vt30 edition v2

Scrubbed my first attempt settings and started again, this time using the APL the large windows. I did greyscale, then played with gamma. One thing I noted on 's settings is that he didn't toch the gamma controls. I'm assuming that I should be able to correct the gamma by adjusting all 3 of RGB at each of the 10 points?

I had largely tried to stick to adjusting just red and blue, and leaving green alone. Andori said:. Thanks for the reply. I can't remember the exact figures, but when I'd done the 10 point greyscale and measured it the gamma figures were coming out at about 2. It is correct to use Green as a ref for greyscale adjusting mainly blue and red. However from the colorimetry perspective REC.

Thanks again. I've also got the Toshiba LCD in the bedroom to play with, but without checking the menus guess that one may be a service menu job to adjust. I've tried several methods on my 42VT30B. The picture didn't look as good using the small APL patterns.

I also ran a Cal using small non-apl windows and large non-apl windows. The method used to obtain the best picture for my set for a greyscale calibration was For 2 point using 80 and 30 get red and blue as minimum error possible and as equal to each other as possible do not touch green.

Once this is achieved go to the respective 10pt gamma control for the stimulus you are working on and adjust until Green is as spot on as it gets. Then go back to the stimulus you are working on and again reduce red and blue equally until it's as close to the target as possible, not touching green. Flick back and forth using gamma to level off green until your dEs are as low as they possible can be. Then move on to the 10 point greyscale calibration using the same technique. Once your calibration is done put on some blu-ray reference material and watch.

You will be most pleasantly surprised with the quality of the images and realness and depth of it all. It worked for my set, it may for yours. I left the 2 point WB settings as they were from the previous effort and just concentrated on the 10 point control.

So, I settled on dRE's of 7. Once I'd done the white balance, gamut was very easy to get in line. I reduced the overall colour control to 28 this time, after reading numerous reports that this was the way to go. Then I just needed to dial in luminance on all primaries and the odd secondary and adjust hue and saturation on the green primary and cyan.

Gamma was a real headache too. I tried to dial these out with the WB controls to no avail. Then when I measured the gamma using the specific patterns and tool in ChromaPure, it showed most the top end was out of line. This doesn't seem to have had any detrimental effects on PQ but, will monitor it. If I left the gamma alone, it averages out at about 2. Anyway, I've attached the report if anyones interested.

I guess your before and after settings are based on your previous calibration, not out of the box settings, right? Your report looks very good. Did you keep the default Brightness and Contrast settings for the set? Last edited: Feb 2, Hi Paul, Thanks for your feedback about your experience. Speeds up calibration exponentially. Yes, there has been talk about getting consistent accurate readings by displaying a scroll bar or anything similar between readings and taking your measurements within 45 seconds of the Scrolling Bar vanishing or whatever you decide to use to get the most accurate readings for this set.

Being consistent with what you decide to display between readings was also advised. I've tried this method and found it works quite well. I ran into the same issue you were having in the end I decided to go with the click were 17 stopped flashing. However is I shoved my nose to the screen you I could make out an ever so faint flashing effect at For brightness and contrast the defaults 30 for B and 36 for C in prof 1 mode seemed spot on for my UK set.

I also left colour at the default of 30 as when doing the gamut initially I dropped colour to 26 to reduce the error in red then calibrated the gamut from there on. After calibration I found the skin tones had a greenish texture to them.

Leaving the colour at the default of 30 and calibrating from there on got rid of that and the skin tones now look very realistic. Maybe on the larger sets this is not an issue but for my 42 inch 30 is spot on also. Just looked up the stuff on ControlCal. Looks like something I'll invest in to go with my copy of CP. Now if I could find a prog to drive my from the PC as well Not sure about the second part.

Maybe asking too much. Interesting findings with regards to adjusting the colour control and the resulting green effect. From what I've read, this is regarded by Blu-ray. All the vivid colours of the Transformers really pop, detail is excellent and again, it all looks totally natural and realistic. All in all, that 6 hours or so 'twiddling knobs' was well worth the effort. Next up in my dad's PS51D Oh, I just noticed in my original reply to you that I wrote using the scrolling bar gave accurate results afterwards.

It didn't. It made getting accurate results much more difficult. I've amended the error. You'll enjoy using ControlCal. How's the picture mate? Green luminance is a bit extreme you nearly ran out of numbers. Picture is looking good Andy and the Green Luminance was a big surprise.

I actualy did run out of numbers and there still was a little Luminance there? You should bring down luminance with your colour setting, try setting your colour at 26 or 27 And then adjust your luminance settings, how's the secondary luminance fiqures like. Quite high. I meant that you bring the luminance down as much as you can on the secondarys with the colour control and then adjust rgb luminance with the luminance controls,.

Will post my new settings a little later. Anyone no why i had to max out on the Green Luminance and should this improve with ageing the GT? Orso Active Member. Bumtious Banned. Barry If you having to adjust the CMS that heavily something is wrong elsewhere. Gamma at 2. Orso is right about green very pioneerish????? There should only be light adjustment needed of the cms, you need to look at your RGB greyscale settings, and the correct manipulation of the RGB's will also settle gamma tracking.

What are you using as a pattern generator, is that correct!!! Seems OK mate but now i am begining to wonder I am hoping these green patches do indeed dissapear in time.
