OK this thread says that 1. is different but 2. - 4. use the same hardware.

Last question: wouldn’t it be better to point the sensor at the screen (using the diffuser) since that way you wrap the screen into the calibration too…?

I thought the
1. Gretag Eye One Pro
2. Gretag Eye One Display2 color meters
3. Pantone Eye-One Display LT (rumors it will be discontinued)
4. Pantone Eye-One Display 2
all used the exact same hardware sensor unit??
And the only difference is that they have different software.
The hardware sure looks the same in the photos.
Can anyone confirm?

And then, why is our geek getting different results with 1. and 2. ?
Does the software somehow treat them differently?

Other pitfalls:
1) forgetting to delete a color profile from Windows
2) forgetting to “default” your DVD software video settings
3) incorrect choice of DVD player video playback defaults for black, etc.
4) Not using 100% color measures with HCFR (some incorrectly use 75%)
5) Not choosing the correct “power saving” video mode in a plasma (can affect contrast/gamma)
6) Not setting contrast/brightness/tint/hue and recording settings prior to running calibration
7) Not disabling Color Correction circuitry in the display prior to calibration (Samsungs–> CCA in service menu)
Not turning off ambient lighting in the room (lamps, sunlight, etc.)

Just a few of the simple mistakes that can throw off an otherwise good calibration session…

Cheers,

Does anybody know if the newest version of HCFR (v 1.22) supports an ambient mode for the Display2 with attached diffuser?

What would be the best diffuser to use with Display2?

Is it beter to point out Display2 toward screen or toward projector lens for accurte measurements DLP front projector?

Thanks,

My Z3 settings probably won’t translate to your Z4 as they are dependent on the red filter over my lens. Another issue with the Z4 that makes it difficult to calibrate is its dynamic iris. You will have to arrive at your own settings, the AVS Forum has an extensive thread on tweaking your projector, so you should check that out.

The Display2 does get the best readings if you use it with the ambient diffuser. AFAIK ColorHCFR still doesn’t have an EyeOne ambient mode. So you will have to follow my technique of taking measurements in Babelcolor and transferring the values to HCFR.

You can also spend $150 on Calman and have Display2 ambient support now.

I am a very big fan of your site!!! I am a geek with family too. I can relate to all your posts. First let me say that all your posts are very informative. I have a Macbook and I will be trying projector calibrations. So i’m writing because I have a Z4 and I am wondering if your Z3 settings would closely match my Z4? Also, I was about to purchase Spyder2 Pro but after reading this I guess I should purchase Eye One Display 2???
