The calibration tag is another broad tag that includes questions about calibrating displays, mice, batteries, printers, etc.
I think it is helpful to have tags specifically about calibration issues, though. I suggest, along the lines of this meta post, that this tag be split up according to what is being calibrated.
New tags would be:
display-calibration
mouse-calibration
printer-calibration
Most of the questions in calibration will go to display-calibration so the other calibration tags may be unnecessary.
Thoughts?
