I was able to order this screen as a free benefit of purchasing the Optoma DV10 projector. Unfortunately, they only delivered to the United States, but through one of the receipt-and-delivery services, I got the screen for a cost that was still substantially less than retail.

I had some doubt about whether it would make a difference. I eventually discovered it did, but I initially didn’t pay enough attention to the instructions. In particular, the instructions say to position the screen so that the bottom of the screen is at seated eye level (i.e. look slightly upwards to the screen).

It achieves its contrast boost by taking the light that would normally scatter to the sides and focusing it back down the centre, in a downward angle. The change in light intensity by moving the eye elevation (sitting vs. standing) is quite noticeable. The screen position in the picture above was a poor one, as it was too low.

Compared to the walls, the colour was much more “blue” - probably from the grey colour, and probably more accurate than the wall.

The screen also has a chemical smell when unrolled. It was stronger when I first got the screen, but even months later has yet to dissipate. I don’t know if it ever will. Perhaps it persists due to infrequent screen use and generally being left rolled up.

Overall, it definitely makes a difference when using the projector during the daytime. It doesn’t substitute for thick curtains, but it turns an unusable image to a tolerable one when complete darkness isn’t an option. I do wish the chemical smell would go away though.
