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).

Another solution to the dreaded interlace problem: very cheap, and often very effective: SUNGLASSES! yes, your Raybans will cut out almost all of the flicker from interlace mode This modern wonder works fine. Although you may have to experiment with different shades to get the right reduction in flicker without losing the colour content of the picture. On A-Max, which is Mono anyway, it works like a dream. The only almost serious problem I have is when typing a listing or trying to read something from paper when I am using this method, it is very difficult to read what is on the page with the Sunnies on. I find that a pair of UV specs (the kind you wear when Skiing) is perfect showing only marginal flicker when several horizontal lines are placed near each other (such as inthe drag bars on Mac windows), everything else is rock steady. If only I could read those listings with those sunnies on, it would be bliss. Peter Sumskas

Well, when I used my glasses, I found that I either a) had left them in the
car and had to go outside and get them to use my computer, or b) Got in my
car on a nice, sunny South Carolina day and discovered that my RayBans were
beside my Amiga. At least the Flicker Master stays where it's supposed to
be. Becides, you get (I think) slightly better flicker reduction at about a
quarter the price (if you don't already have a good pair of shades).
I use my Amiga exclusively in Interlace now, and my head doesn't hurt
anymore.
