Hi guys,

I saw the dummies tutorial, and buy one Eye Lt,

But maybe I need a lot of help over here...
check my graphics, and also, How can I do something better?

.

Before:






After

I´m using this on my Samsung 50' 1080p LCD Tv.


tks4 the help...

Well that's much better, but you still have some work to do. I'm guessing those are the low-IRE data points near 9300? Except low-IRE measurements generally tend to read red, not blue. I don't know how the Eye-One does in low lumens.

Here are a few things to do:

1. Do a Primary & Secondary measurement, and post the resulting CIE diagram. That will tell us if your primaries are off.
2. Post the Luminance graph, Gamma graph, RGB Levels graph, and color temp graph. Those tell a lot more about your grayscale performance than the CIE diagram.

I can't access them without registering at the site. Can you post them here?

This BD has subtitles? My disc is from amazon.com, here in brazil I find a guy selling this same BD, but with subtitles included, spanish and english, this is true?...


thanks ...

Can't help you on BD DVE -- I don't have it.

OK, your "before" is really terrible, with everything badly skewed toward blue. You knew that, but I'm a bit surprised at how bad some of the charts look. Did you figure out why everything was so consistently blue?

Your "after" results are much better. I'll bet your colors look a WHOLE lot better now!! As I suspected, the worst points on the CIE diagram are for 0 and 10 IRE. Probes often don't read well at those low levels so it's hard to say whether it's a problem with your calibration or a limitation of your probe, but I'd suspect the probe. Don't worry too much about those unless you notice the really dark areas looking noticeably blue-ish.

You didn't include primaries and secondaries on the CIE chart so I can't tell how those are.

The Luminance and Gamma charts show that your luminance levels at various IRE levels are off, resulting in a high gamma (low brightness) at low IREs, and low gamma (high brightness) in the 40-80% range. This means your low-level areas (shadow details, things like that) are too dark, and mid-level areas (most areas on the screen, usually) are too bright. It may be hard to see detail in dark areas.

Your color temp results are not too bad. You want the delta E (magenta line on the RGB Levels chart, which shows how far off you are from the ideal D6500 color temp) to be as low as possible. Yours are under 10 for 20-100%. You can certainly do better but that's pretty good.

Now, what to do? There I can't help you much. I have no idea how to adjust your Samsung. If you have the ability to tweak color levels at different IRE levels, that would be my first recommendation. R & G are too high from 40-80%, and B is too high 40-90%.

I don't see any 50" LCD's on the Samsung site, but all the 46-55" TV's are "Series 6" and are probably similar. But the manuals don't cover anything about calibration so I can't offer any suggestions.
