Alr Screen Projector Placement

This is my fourth ALR (ambient light reflecting) screen. The first thing to know is, there are no miracle screens. There are good ALR screens, but none perform miracles. Even the best don't show a great picture in a really bright room. The second thing to know is, don't necessarily believe the promotional pictures and videos from manufacturers that show amazing screen performance. They have positioned the screens, projectors and cameras to show the screens at their very best. You are unlikely to duplicate this in a real world situation. Almost all ALR screens have, to one extent or another, a major problem – screen artifacts. Shimmering, hot spots, sparkles, grainy appearance and so on. In order to eliminate this problem I have owned four different screens. My newest one, which wasn't available when I first started my quest for better picture quality, the Da-Lite Parallax, has none of these problems. Zero! The Parallax probably doesn't have quite as good of ambient light rejection properties as some of the other screens, but with some light control and careful placement of light sources, you can still have light in the room and a great picture. A great artifact free picture is really important now that we have 4K material to watch.

We use this projector screen in our church activities.

The new system (bracket) for aligning the screen protector makes placement so much easier than before.

We needed to place an outdoor projector on a stand that was sturdy and flexible in projector placement. This certainly did the job. We simply attached the correct size platform for our projector. It is portable, light, but sturdy and can take a much heavier loads than we are using it for.

I installed them next to my projector screen and they sound great.

Anyone looking to extend there monitor onto a TV screen or projector this is the way to go.

The plastic setting case is really nice. It take away my guess work on the placement of the screen protector.

Using this to decode an NDI source to a projector in Church services with live stream. We previously were sending the Presentation Laptops screen to the OBS computer via NDI, and used a separate proprietary wireless video feed to the main projector. Got this so we can use the same NDI source for both and eliminate the wireless projector feed. It is working well. One thing to be aware of: the projector will display will go blank in a couple of seconds if there is no video and audio activity when using NDI Screen Capture as the source. This can be an issue during power points with static screens. You can set the decoder to keep the last thing displayed on the screen or allow it to go blank. I prefer it to go blank so I know something is wrong right away. You can also resolve by making sure the NDI Screen Capture is using an active audio source (like the microphone). This decoder has been reliable and is reasonably priced. Perhaps other decoders won't have the inactivity issue but they are also more expensive. This has not been a show stopper for us.

Just placed on camera, so cannot comment on long-term use. Placement is somewhat technical, but when instructions are followed, it set on the screen very nicely. No issues so far.

I have used these for various cameras for years and they work very well. The trick is cleaning the screen really well before placement. After taking the protector off, no residue is left.
