Okay, this means the best would result would be to set -t to the exakt value of the color temperature set up (like 6385), right? > > And as far as I understood until now, the only possibility is load the > > .cal-file or the vgct tag to the first monitor with dispwin (at least > > when I do my photo work) > Just do it at startup. Why would you only do this only at certain times? Because it would only calibrate the left display resulting in a significant difference of the background pictures which is annoying when doing normal office work. > Well sort of.

I'll try to load it with dispwin -I. -- Volker Sauer * Poststrasse 1/601 * 64293 Darmstadt * Germany E-Mail/Jabber: vsauer(at)volker-sauer.de * http://www.volker-sauer.de PGPKey-Fingerprint: DB26 11C7 B12E 0B27 3999 2E4F 7E35 4E4D 5DD5 D0E0 http://wwwkeys.de.pgp.net/pks/lookup?op=get&search=0x7E354E4D5DD5D0E0
