Q.
A. It doesn't really matter what kind of monitor it is per se. The difference is in the refresh rate. You change those settings when you
Start -> Control Panel -> Adjust screen resolution -> Advanced Settings -> Monitor Tab. Then change your screen refresh rate to about 75 Hz. If you don't have that option then decrease your screen resolution to a lower setting. This will help you if you are eyes are straining to view the monitor.

Can lcd-crt / crt-crt dual monitor pairs cause eye strain?
Q. I heard that CRT monitors paired in a dual monitor array can flicker due to alternating frequencies in the two monitors, and it's better to pair LCD-LCD
Also, that the frequency of the display on a CRT is different from that of an LCD making it so pairing a LCD with a CRT can cause eye strain.
Is there any information about this, either confirming or denying?
Any information will be helpful, and if you can provide links to inforamtion on the web from reputable sources, that would be greatly appreciated.

A. CRTs are susceptible to magnetic interference from other pieces of equipment, including other CRTs.
Typically when you put 2 CRTs next to each other, driven independently at the same refresh rate, what you will get is a horizontal bar of distortion going slowly up on one screen and slowly down on the other.
Whether you will see this depends on if the dual head video card syncs up the two monitors. If it does then you will be O.K. If it does not, or if you use multiple video cards, then you would need to separate the two CRTs - 4 inches (10 cm) is usually enough.
For a CRT/LCD combo, you should be able to set the refresh rate independently for each monitor. So you can run the LCD at 60 Hz and the CRT at 75 or 85 Hz.
You will get eye strain if you stare at anything for an extended time. CRT, LCD or even a newspaper. Take breaks. close your eyes for a second or two every few minutes (When you stare you don't blink enough and you eyes get dry) Sit back and stretch every so often. Once an hour or so get up and move about.
