Like many members, I am trying to convert my CRT machines to LCD machines.  I picked up a few LCD monitors today and was expecting them to look the same in the back as my CRT monitors, but they are slightly different.  Both monitors have 25 holes....which I believe makes then 25 Pins.....but the CRT monitors (Kortek KT1782-AO1) have 22 needles while the LCD monitors (Ceronix 1705-LCD) have just 18 needles.  Am I able to use these LCD monitors with my current set-up or do they need to have 22 needles?  Thanks for your insights!
