[visionlist] update on CRT's

[Sergio Navega]

Sorry if my question is naive, but what are the uses for a 
monitor with more than 80 Hz frame rate? Surely it cannot be
something related to human visual perception, which is why
I'm curious.

  Thanks to the many colleagues who have sent me suggestions and information in response to my recent inquiry.  

  I will send a summary of the suggestions soon.  As we know, many manufacturers, including Sony, Iiyama, and apparently Mitsubishi, no longer sell CRT monitors.  

  The fastest currently available model that I have found is from NEC, their model AS120-BK, AccuSync 120-BK.  It supports a 200 Hz frame rate.  

  The spec sheet only lists the following:

  Resolutions Supported:  

  640 x 480 @ 60 to 188 Hz

  800 x 600 @ 55 to 153 Hz

  832 x 624 @ 55 to 144 Hz

  1024 x 768 @ 55 to 119 Hz

  1152 x 870 @ 55 to 105 Hz

  1280 x 1024 @ 55 to 89 Hz

  1600 x 1200 @ 55 to 76 Hz

   

  However, in talking to the tech support staff, they say that 200 Hz can be used with the 640 x 480 resolution.

  Another bit of information is that the manufacturers do not exhaustively test these monitors, and sometimes they will do better than the specs, which are simply what they have tested and are willing to vouch for.  (However, running the monitor beyond the nominal range may shorten its lifetime.)

  If anyone has one of the NEC monitors and could test the high end of its performance, it would be valuable information not otherwise available.
