Hello!
I calibrated my monitor sometime last year and I just found out that monitors can drift over time so I am keen to re-calibrate/update the calibration.
How do I go about doing this accurately? Do I start fresh; i.e ‘settings’ is currently my previous profile so do I change this to Default Gamma 2.2 or…?
Also the testchart; this is also currently selected as my previous profile, what do I select this time?
Many thanks!

2018-08-15 at 22:21 #13161Hi,
as the old profile is from a year ago, I’d just redo the whole calibration and profile (e.g. with the last profile selected, you can use the previous settings).
2018-08-15 at 23:32 #13168So once I’ve done re-done the profile, how do I then go about keeping it ‘updated’, if that makes sense? The process for me took a couple of hours (was worth it, my prints came out 100% accurate).
2018-08-16 at 0:33 #13170A few hours? What’s the instrument you’re using, and what calibration speed/profiling testchart size?
2018-08-16 at 19:06 #13182I’m using the Spyder 5 Express with the software downloaded via DisplayCal. I have attached a photo with testcharts etc.

2018-08-17 at 21:24 #13200Will that still give as accurate results?
2018-08-18 at 1:14 #13201I have a follow up question. I re did the profile from scratch, worked out fine but when I ran the verification tool (I did it twice just for fun) I noticed I got a vastly different results. See attachments.

Not quite, but the difference is probably academic so I wouldn’t worry about it especially with the Spyder.

Doesn’t look that different to me (only looking at the overview obviously), average is ~0.6 dE in both cases, and max ~3 vs ~4 on a dark Rec. 709 blue (which is probably slightly out of gamut on your display anyway). The Spyder having a measurement inaccuracy for darker colors of around 1 dE seems in line with its expected performance.
