Not sure polarization level of film I used.As a side note I dug back some old posts of Xor, and despite his polarizer not being a suitable solution IMO, it's still interesting with some perspective. In particular, the resultat he obtained was probably not as problematic as expectable regarding transmittance because he used a low quality polarizer with polarization efficiency in the 92-96% range. That allowed a transmittance of 48% which is higher than most if not all quality polarizer sheets.
My film was bad because it had adhesive and I have no way (or rather tools and skill...) to put it properly.
Optically image quality is very good. Image is sharp as are colors. My guess would be that optically polarizer films will be better than any other films...
Reflection reduction with polarizer is very good. There is vastly less glare than on other Trinitron CRTs. I would say every single CRT I saw have terrible glare and reflection reduction. In this regard polarizer is in its own class.
There seems to be reduction in electrostatic effect with polarizer. I have not tested it really but very aggressive effects that appeared after removing original coating are gone making it more similar to other CRTs.
And of course and this is the main point: FW900 with polarizer can be used with light in room and contrast ratio is perceptually improved just like on LCDs. Even with main roof lights on black is black.
Circular polarizer might be hard to come with proper size to fit FW900. Someone in this thread (do not remember name) bought sheet I recommended to him but it had some diagonal lines on parts of film making it unsuitable to put on screen. Linear polarizer is it seems our only option. But given already low transmittance and great glare reduction going circular might be overkill...
