That seems excessive, no? That would imply an uncalibrated monitor changes like crazy every few weeks. And while I can't say that's not the case, it sure doesn't seem like it is. But who knows, maybe they do run amok within a couple of weeks. I guess I'll have to pick one up and see for myself.
Dave, honestly I don't know whether every 2 weeks is excessive or not. Before I bought it, I watched several YouTube videos all of which stated they recalibrated every 2 weeks plus everything I read about it online said every 2 weeks. I just pulled out the directions but there isn't anything specified about recalibrating. Once the monitor is calibrated, the default setting is every 2 weeks although you have the option to override it like I did when I chose every month. Since I just recalibrated, I don't know the longest duration of time they allow. I'll try to remember to check the next time I do it.
