Colors differ after calibration

[Ralphy4]

Hi! I have a Spyder5 and calibrated a screen for the very first time. I got some unexpected results and hope to get an explanation here.

So, I connected an external monitor to my laptop via DisplayPort. I calibrated both of them using DisplayCAL and the Spyder5.

I set the white point to 6500K, brightness to 120 and gamma to 2.2.

In the next step I made all the RGB bars meet in the middle and set the brightness to 120. As my laptop does not have settings for RGB I did not adjust those.

Calibration went through and I got 100 resp. 97% sRGB in the end. Average Δe was around 0.5 in for both displays. Seems decent for me.

What strikes me is that next to each other they look pretty different even after calibration. One has a clear red the other a green tint.

Shouldn’t they look the same? Isn’t that the point of color calibration?

Spyders are innacurate, always were that bad, and they degrade => you have a very innacurate device, its expected that white will be off.
Buy an i1d3 from Xrite (i1displaypro, i1display studio).

Also colorimeters need a correction for each backlight type (each “flavor” of spectral power distribution). For sRGB only LED display  a generic one should be “White LED” or something like that. If you did not use it, re do… but Spyders are innacurate so do not expect a mircle.

Also you can use visual whitepoint editor: match them by eye. Grey will be calibrated to match the same color.

Thank you very much! What’s strange is that the Sypder creates the same tints every time. I did do the calibration process around 20 times. The one with the normal precision. If it was device degradation or low device accuracy I would expect different results per calibration. Yet it is consistent between calibrations.

Maybe it is inaccurate and degraded and that results in some inaccurate results but it seems there is something else going on in addition.

EDIT: there are many settings I left untouched as I don’t know what they are for. Maybe I need to change one or a few of them? Like white/black level drift compensation, observer or black point correction.

It degrades over time, with years. Also out of the box is innacurate.

Get an i1d3 or use visual whitepoint editor
