It belongs to work. About twice a year I bring it home and calibrate all monitors in my house. <br>I calibrated my 20" Apple Cinema Display... it's 5? years old. The original 20". <br>It still holds a calibration quite well. The eye one software allows for a before/after when it finishes... I could hardly see a difference. The only real diff is that I had too turn up the brightness some more. I believe a couple of years ago the brightness was up to about 60% on the slider. Now it's at 75-80%. I can see this LCD lasting a coupla more years. <br><br>
