Hi all !

First of all, a big thank you to the people involved in displayCal and argyllCMS development, and helping and sharing on the forum. Last time I used it was some years ago and it seems like a lot of work has been done since then !

I have a sony vaio pro 13 laptop and a secondary monitor (HP Pavilion 23xi). As you can see, no professional material but should be ok for amateur photography… ?

I’m trying to calibrate my displays, with no success. I suppose the problem is between keyboard and chair…

I first went through the calibration process (see results attached FIRST_HP23xi_ect…), and checked with Measurment report, everything was OK (errors << recommended values, average deltaE 0.4, maximum deltaE 2.4). BUT my contrast was very low (114:1). I found out that it was due to the HDMI connection and a bad configuration of dynamic range, and fixed it (Intel graphics, HDMI -> full range).

Having fixed this, I run the calibration process again, obtain a contrast over 800:1 at 100cd/m2, but HUGE errors in the measurment report, with an average Delta E of 6.8 (maximum 15). I attached the profile and all infos in SECOND_HP_23xi_etc…. I tried four times, with different calibration speed and profile quality but no success.

My screen is calibrated at 6000k and 100cd/m2, this seems to be OK, but in the report I dont understand the different lines about whitepoint :

• Display profile whitepoint 6504
• Measured whitepoint 6008
• Assumed target 6000

What am i doing wrong ?

I would like to fix this before calibrating my laptop’s display…

Thanks for reading !

Clement
