10/29   My CRT monitor at work got upgraded from one old type to another,
        perhaps less old one.  It is brighter, has more contrast and
        seemed generally better at first.  However, after a while my vision
        seems to be getting kind of blurred.  Is this a problem with the
        CRT's convergence (focusing of the electron beams)?  Is there a
        practical way to adjust convergence?  It seems difficult to fine-
        tune that when the difference shows up only over a while.
        \_ Stop drinking.
        \_ Did the configuration change?  What's the refresh rate that you
           are using with the new monitor?  - misha.
        \_ Make sure the contrast/brightness setting is within
           reasonable range. More and more newer monitors are shipped
           with 100% contrast setting, which is NOT good for your eye.
           http://www.displaymate.com and download their demo version.  Make
                \_ payware? BLECH!
           sure the refresh rate is 75 or 85. Not 60 or too high.
           \_ What kind of bullshit reason do you have for saying "not too high"
              \_ Do you have clinical evidence against the previous poster's
                 statement?
           Everyone who works long hours in front of computers should
           calibrate their monitor.
              \_ CRTs are band-limited and over-doing the refresh rate
                 just cuts your pixel accuracy within each scanline.
                 \_ wtf does "band-limited" mean?  Each the monitor supports
                    a certain mode or it doesn't and it stops displaying.
