[NTLUG:Discuss] Monitor Unsync [might be OT]

[severian@pobox.com]

Harshal,
   I have not seen a study about the medical value of high refresh rates on 
LCD monitors.  CRTs with a refresh rate of only 60 Hz have a noticable 
flicker to me   I don't notice that with an LCD.  But LCD monitors don't 
draw the same way.  With a CRT, you have an electon beam(or 3) tracing over 
every phosphor dot on the screen.  For a LCD(active matrix), you have a 
switch at every pixel that turns on and off as instructed.  There is no 
phosphor decay.
   Even with those advantages of an LCD, my 15 inch trinitron is sharper 
than any LCD I have seen and that is what I prefer to use for long 
sessions.  If you have any good pointers, let me know.
Good day,
Ralph
