Not exactly 60Hz refresh rate

Does anyone knwo why sometimes the monitor refresh rates are marginally lower than full 60Hz.  I mean 59.997Hz is basically 60Hz, but its odd that it says that.

 

Also in the NVIDIA control panel it does say 60Hz for this monitor.

Back in the days of the b&w television, the NTSC standard was 60 fields per second. However when colour television came around, they reasiled it would distort the audio signal. To compensate with that, they went on and slowed down the field rate to 59.9. To keep the compatibility of digital equipment with its analogue counterparts, they kept the framerate on the DVDs and DV cassettes. Even today, in th digital age, NTSC cameras still record in decimal framerates.

But it isn't 59.94 Hz as you would expect the NTSC frequency to be, 59.997 Hz is a much smaller deviation. In this case it's due to pixel clock rounding, not NTSC frame rate standards.

There were no framerate abbreviations before NTSC
