I use a Polaroid "Contrast Enhancing Filter".  This is a polarizing
thing, with the fornt surface anti-reflection coated.  Since flicker is
brightness sensitive, it will help, but you can always turn down the
contrast setting to get the same effect.  The BIG advantage of this
filter is that, withe the a-r coating and the polarizers, the blackness
of the black end of the scale is improved.
I am sitting in front of the screen in a well lit room wearing a white
lab-coat, and can barely detect its reflction in the screen, and the
sunlit scene out the window behind me is but a small, faint diffuse
blob.

The BAD news is that, in this country at least, the CEP will cost you an
arm and a leg.  But it is GOOD!  I would still use it with a Flicker
Fixer, as it enhances the contrast with only about 10dB peak brightness
reduction.  You can nearly make that up by driving the monitor harder.
I have a 1084 with the high brightness tube (the one that looks light
silver when turned off).
