Hi Kal,
Thanks for the excellent guide. I have a Samsung rear projection DLP. You mention that it is best to set contrast so that my ftl reading will be 30-40. My question is where specifically in this range should I aim for? Should I do an average of approximately 35 ftl?

Also, since contrast is the first thing adjusted, does it matter what brightness is set to at that time, or should I use my TV's default setting of 50?

Hello.

I just stumbled upon the Greyscale & Colour Calibration for Dummies a week ago. Since then, I have purchased the i1 LT and followed the guide to calibrate my Sony XBR4.

Attached is my calibrated grayscale. I have only been at it a week, but can someone suggest what settings to tweak to improve my grayscale in the lower (0-30) IRE's?

Should I adjust the over brightness so that the lowe IRE's can be read by the i1 LT?

Thanks.

Hallo everybody

Very good TUT....
I've a question how good are the software which is sold with the eye-one display 2 ?

I would like to use the dummy guide .... but after i while, i wonder if the eye one software as good as the hcfr software to calibrate my home equipment?

Or is the hcfr software more accurate then the allinone eye2-one software solution ?

Whats the difference does anybody know. ?

Sorry for my bad english:)

Just a few quick questions regarding calibration with the Eye One. I did a good bit of calibration a few months ago when I first got the colorimeter but have not touched it since. Now that I have added the XG-FULLHD card as well as a VP50 scaler I figured it was time to redo the grayscale on my XG. So, after a few runs at this last night I find that the following two items need attention:

1. My Delta E numbers are pretty good except for at 0IRE and 10IRE. I have WAY too much red, so much so that's it's visible in the test pattern. What can I do to tone that down without affecting the rest of the grayscale?

2. I'm having a terrible time getting gamma to 2.22. My luminance curve is a good bit above where it should be even after lowering my brightness to almost "crushing" levels with the 0IRE pluge pattern. The best gamma reading so far is 1.92. So does this mean I have the gamma adjusted too high in the Moome card since lower numbers mean higher gamma? Is this where I should be making an adjustment?

Are there any Possibilities to save with HCFR the Black Level Sensor Offset Calibaration`?

Or should i have to do this if want to restart the software again and again?

Love the guide. That goes almost without saying. I am a long time forum lurker in alot of forums and participate heavily in Video Card forums elsewhere and this has to be the coolest internet based tech guide I have seen someone throw together without a pricetag attached to it. Bravo!! Very Happy

Can I get some opinions on the following please? I am about ready to get into adjusting the greyscale. First I am choosing my starting point Contrast and Brightness settings as outlined in the guide. With that in mind, which of these two Contrast/Brightness settings is the better "jumping off point" before I get started with adjusting my Greyscale?

They both have my PZ85U brightness set at 52 but one is 60 Contrast and the other is 90. I have been trying DVE and Getgray and AVS 709 from a BD35 over HDMI is my source. In all cases, the 1 or 2% just above black bars/detail are just barely visible on the screen using the patterns on getgray/DVE and the Black 17 bar and above is flashing for me with AVS709's black clipping pattern. As for Contrast, there is no clipping near white detail at either 60 or 90. At 60 Contrast, you can see a few more white bars above white 235 flash using AVS 709's white clipping pattern than you see with 90 but not many more. At 90 Contrast, two bars above 235 are still flashing. At 60 Contrast there are 4 bars above 235 flashing.

As you can see below, at 60 the light output peaks at just under 34 ftL and at 90 just over 34 ftL. That is when using Getgray DVD. Using the DVE (not pictured below) the curves are all the same. Just that DVE uses smaller grey box patterns and as a result the ftL is perceived as brighter by the i1 Display LT I am using by a value of 1ftL. So just under 35 ftL with the DVE pattern 100% white window at 60 Contrast and at 90 it's just over 35 ftL.

Enough of my blabbing. Here are my screenshots from the software...

Are either of these going to be an easier to start from?

DVE versions of the 2 settings are attached as well. Smile

OPTION 1... CONTRAST @ 60

OPTION 2... CONTRAST @ 90
