Just to make sure I got the message: also x,y will be affected by the ABL and not only Y? Although the x,y deviation numbers for most colors are pretty low (especially for white), they are a fair bit worse than the i1 pro 2 repeatability...

I'm using an Iscan Duo as a signal generator and a WDLive TV media player displaying the AVSHD patterns in the "Calman Windows" folder. I'm using 32% (10.24% of screen area) for the Duo but the AVSHD patterns are a bit larger. My main...

Thank you for your excellent reply as usual. I feel this is important to know for people using both calibration packages. The discrepancy always appears to be in the normalizing luminance part. I'm not keen on starting a debate on who is...

The white reading was x= 0,3171 y= 0,3247 Y= 124,9846 So, the calculator on Bruce's side is also not entirely accurate?

Thank you for those links Tom. Much appreciated. Sorry it took me this much time to come back to this. Could someone check these numbers I've tested please? For Red x = 0.6480 y = 0.3301 Y = 15.0681 White Y (75% stim) was measured at...

oh, I see thanks. But even if they were large (only talking about errors for Y here) that still would not really matter as long als the Y reading varies linear with changes in brightness. So what would be the reason to correct Y if then,...

Hi Zoyd, I'm not sure I understoon that properly. We can't make a non-linear colori- or spectrophotometer beter with profling as it is done now: we only measure 75% or 100% stimulus for white and the primary and secondary colors and...

Thank you all for the excellent information. Joe, why is display linearity an issue with profiling? Unless, I have not understood you correctly and you are *not* linking a non-linear display device to meter profiling. I understand it...

So, If I'm getting this right, as long as big Y varies correctly (relatively speaking) when the stimulus of a pattern changes, everything is fine = accurate. However, I'm sure I've read about this before and a large disagreement ensued,...

Quote:Originally Posted by Michael TLV Greetings In the ideal, the c6 (or similar device) should read relatively the same [...] So for x,y relatively the same is a maximum error of 0,002 - 0,003 considering the tools I'm using. But...
