Hi all!
I recently installed the new Psychtoolbox 2.5. I decided to recalibrate
my monitor, but to my surprise I did not obtain what I expected from the
calibration (see screendumps below). My system is a PowerMac 8500/180
with a Sonnet Crescendo G4/350 upgrade and an ATi Radeon 32Mb Mac
Edition with the latest drivers installed running Matlab 5.2.1 under
MacOS 9.2.2.
This is the Matlab output during calibration:
******
Which screen to calibrate [0]:
Enter RGB values for background as a row vector [190 190 190]:
Enter distance from meter to screen (in meters): [0.7]:
Enter monitor name: ViewSonic P225ƒ
Enter your name: Zoran
Describe the calibration: Standard
Save codes:
0 - screenX.mat
1 - string.mat
2 - default.mat
Enter save code [0]:
If colorimeter is off, turn it on
Hit any key to proceed past this message and display a box.
Focus radiometer on the displayed box.
Once meter is set up, hit any key - you will get 10 seconds
to leave room.
Pausing for 10 seconds ... done
