Problem with screen flicker

[Marianne King]

I have a DecStation 3100/Ultrix with the standard DEC 15 inch color monitor.
I am having a problem with screen flicker.  A DEC technician looked at
my machine and told me that according to the diagnostics that the
monitor is functioning properly and that the flicker does not occur
where they ran the tests.  They told me there must be something around
my office which is causing the problem.  However, that answer does not
help me much.

I have heard several theories about this problem including that the DEC
color monitors just do not work very well and that they have a problem
with an adequate refresh rate.

Has anybody had this problem?  If so, please let me know.

Thanks in advance.
