Kal,

Can we have the mathetic calculations for setting the secondary color luminance values? For instance, your guide and Tom's guide recommended that red should be about 21% of white's luminance. But both guides skipped the calculations for the secondary colors.

Kal I literally just signed up to thank you so much for your guide. I recently bought a LG 50PZ750 and had been searching for a budget concious way to have it calibrated. I used the DVE-HD disk and was fairly happy with the results, however seeing all those greyscale and CMS numbers just sitting at zero was haunting me. While browsing around last week I stumbled across your guide and read the entire thing, confident I could do this I found an eye one on eBay for 45 bucks. Once it arrived I started setting things up and was pretty shocked at how close the tv was out of the box with most delta Es near or around 10...plus my D65 readings were all spread pretty close to the optimal setting. I did run the greyscale though and loved that my tv has a 20 point ire system. So I kinda strayed from your guide, but thanks to you I knew exactly what I was looking for in each ire point and when finished my D65 all pretty much sat on top each other and my delta Es were all below 3. YAY!!!! Then onto the CMS, and when finished I had one beautiful television picture. Thanks to your guide, something that would have cost me 200 bucks at Best Buy only cost me about 65 bucks. Again thank you thank you thank you.

I do have one question, on my color management the closest I could get on blue and red were 10.5 DeltaE and 12.8 DeltaE respectfully, all my other colors were under 10 and near 3, and my triangle nearly sat on top of the reference triangle. Is this my particular display? I will say that I have my color gamut set as wide instead of standard, is standard possibly closer, and if I change from wide to standard will I have to redo the whole greyscale? Thanks again.

I retried with setting it to standard, ended up switching it back and played with the colors that were off. I was able to get everything except that pesky blue under 10 no matter what I did it wouldn't get closer than 12.1. However, it's barely noticeable when watching programs, so it's where it'll stay. For what I payed, compared to what I would've payed a pro, the results are unbelievable. Again thank you for the guide. I most definitely will be passing on the word.

Oh yeah and thanks for the input Ron. For what I payed for this tv, an absolute steal at ABC Warehouse, and what I payed to DIY my calibration I have no complaints. It sure was frustrating though when trying to set it I'd move the Blue Color and Blue Tint setting in both directions and the x value would pop all over the place but the y value would just mock me and sit in place or move further away from its point. So I just got the x value as close as it would let me without letting the the y move to far out. Frustrating indeed but when I turned it on direcTV even my wife commented on how good the picture looks, and normally shes just meh about those things and says "a tv picture is a tv picture." lol

So I have a question, I just was looking at my greyscale ramp and noticed that the mid range is kind of yellowish is this normal after calibration? Could I have a bad i1? Should I calibrate it often maybe cause of the warmth of the plasma?Please help this driving me nuts.

I think I figured out what it was my gamma level was straight till about 70 then spiked, then fell way down past 1.3...I had my contrast at ftl 35 dropped it down to about 30 and redid the greyscale. The color tinge in the greyscale ramp, it's the 'reverse greyscale ramp' on DVE DVD, went away after I did the above steps. And the gamma is in a straight line..

I have noticed something else lately I used the DVE on my PS3 to set the black level and on directv it seems just a bit bright. I got lucky today and was able to record an smpte color bar that popped up during a show. When using the i1 I had to eyeball my level from PS3 as you mentioned in your guide we might have to do. So my question is do different sources have different black levels? Basically, is using the smpte color bars directly from the source a better way to set black level, or am I better off keeping with the DVE black level?

Hi all,
I'm about to buy an used eye-one pro. Which combo should I use? i1 pro + i1display 2 or i1 pro+ i1display 3? My budget is low so i1display 2 probally the best choice, I ain't looking for absolutely perfection but just wonder; Is a profilied i1Display 3 much better than a profilied i1Display 2?

It's impossible to give hard and fast "accuracy" numbers to any meter. It depends on all sorts of factors including exactly what you're measuring.

That said you should get pretty accurate results if you use the i1 Pro to calibrate the D2 assuming the D2 isn't way off to begin with and i1 Pro works correctly.
