These are some of the rear-projection films successfully used by forum members. This is by no means a comprehensive list, so please feel free to add any information you may come across! Taken from this thread: [1]

Polymex 50 micron double matte drafting film ($2 USD sq. m) [2] item no. F050DDD

Rosco Grey ($12 USD sq. m) [3] (choose "grey")

mind.unity@gmail.com’s film ($90 USD sq. m) see this thread for details: [4]

IFOHA Digiline White (169 EURO sq. m) [5]

IFOHA Digiline Contrast (230 EURO sq. m) [6]

3M Vikuiti ($566 USD sq. m) [7]

You may notice how dark the Vikuiti looks in comparison to the other films--this is not an error. The black level and color contrast are much better than the cheaper films, but without a sufficiently bright projector the image is dull (my projector is 1200 lumens). If you had a 3000 lumen projector it would look stunning. The Vikuiti is also the only film that has a restricted viewing angle. I would estimate it to be roughly 90 degrees (compared to 160-170 for average LCD monitor), which could severely limit its suitability for tables. You can see this in the images where the Vikuiti is slightly curled away from the window at its top edge.

Here are my personal opinions of the films:

*Drafting film: Nice and bright but looks washed out and has the lowest contrast ratio. Best price to performance ratio by far;

*Rosco Grey: Kind of the worst of both worlds. It’s too thick to have a bright picture, the contrast ratio isn’t all that great, and the image tends to look blurry. Inexpensive but my least favorite;

*mind.unity’s film: Brighter than the Rosco but still doesn’t quite get nice pure whites like the more expensive films or the drafting film. This is probably the sweet spot for budget projects that want to keep the costs below a few hundred dollars.

*IFOHA Digiline White: Matches the brightness of the drafting film but less washed out and with deeper blacks. This film has a very harsh projector hotspot if you are standing directly in front of it, however.

*IFOHA Digiline Contrast: Great balance between brightness and contrast, and no projector hotspots. This is my favorite of the bunch but a little pricey for hobby tables. $145 for a 45” 16:9 sheet (125 Euros, 114 cm).

*3M Vikuiti: Paired with a bright projector, the Vikuiti can match the contrast ratio and color reproduction of an expensive LCD, but with the narrow viewing angle and exorbitant price, I can’t really think of a reason to recommend it to anyone.

*Screen Solutions International: Three Versions of projection film, White, Clear, Dark, Dark works like Vikuiti and is a high contrast film, White (Accent) is my preferred film. All three films are cost effective and most people could buy direct as dealer
