I run an IBM P96 CRT as my primary monitor and a cheapy, Samsung SyncMaster 225BW LCD as my second display. Years ago I went through some adjusting to make my CRT “true”, no calibration scanner, just a few tweaks. And it has been pretty good. Unfortunately what I do in order to get the CRT right, fowls up the LCD, since only one profile is run at a time. If I sold some work, I would have justification to buy a spyder or something, but I have not sold much. The shop I use, on the few occasions that I make prints, always adjust things slightly anyway. So in the end, it’s no real problem.
After adjusting, for 2.2 gama, this image should show no color casts and as set, I see almost none.
