[visionlist] CRT's and frame rates

[vincent ferrera]

You can also check ebay.  And you don't have to guess about the refresh 
rate.  If you have the model number, just google the specs.  We have a 
Sony multiscan 20seII that is about 10 years old and still going 
strong.  It's rated up to 160 Hz, but I think we've gone higher than 
that.

The Sony CPD-E540 is rated to 170Hz, but again, you can probably go 
higher.  I think the key spec is the overall bandwidth (sometimes 
called "max sync rate" or "dot rate") which is the product of the 
vertical and horizontal refresh rate.  Look for the monitors with the 
greatest maximum resolution, smallest dot pitch, and highest sync rate, 
then tweak your video output to optimize the spatial and temporal 
resolution for your application.
