Anyone have any ideas for the false patch 2 reading? This is repeatable.
Is this with dispread ? One explanation would be that there is a synchronization problem. The code sleeps for 60 msec after changing a color (which at 50Hz or more, is at least 3 refreshes), but perhaps the delay with some cards, software and displays is longer than that ? Another explanation would be that your display has some sort of "auto contrast" adjustment mode on, and it takes some seconds to react to image contents. Such a mode is (of course incompatible with color management. What operating system version are you running on ? Graeme Gill.
