The advantages of passive 3D include simple, lightweight glasses that don’t need batteries, and usually cleaner pictures with no crosstalk artifacts. There’s no camera on the keyboard deck, so if you flip the laptop around into tablet mode, you won’t be able to take pictures. That said, the Chromebook Flip C436 has a strong and smooth hinge, whether you flip the screen all the way around or just use it as a laptop. If you want the best of both worlds, an image that is both bright at the center as well as from all viewing angles, use the Supernova with a high lumen projector. Most ALR screens introduce some degree of visible texture into the image that does not come from the projector. That’s not terribly inspiring (Samsung promises 11 hours of video playback, a number I couldn’t come close to), but it’s not the total disaster I experienced the first few times I used the Galaxy Book. Speaking of voice controls, the Galaxy Buds Live gives you always-on Bixby for the first time. In the first contrast test with side illumination only, it did not do quite as well, but it measured a very respectable 27:1 against a maximum of 36:1 and a minimum of 16:1. So overall, it is one of the stronger ALR screens as far as defeating ambient light from multiple directions is concerned.
The White House, the Federal Trade Commission and multiple states have backed right-to-repair measures that could have forced Apple’s hand. Not surprisingly, each of the ALR screens in this review measured much higher in contrast than the neutral white test board. But beyond that, the DarkStar 9’s advantage in contrast grew when the ceiling floods were turned on — in that test the DarkStar9 didn’t lose much contrast at all, reading 17:1 by holding an excellent black level (second only to the SI Black Diamond in this test). The second difference is that the DarkStar9 manifests an extremely low level of texture artifacts. If there is a high level of ambient light in your premises, a minimum of 3,000 ANSI lumens is required. Typically it looks like the fine grain in a photograph taken on high ISO film, or the noise in a digital photograph taken at a high ISO setting. The Epson Home Cinema 1440 that we used as a source projector for these tests is bright but not as high in contrast as conventional home theater projectors. That being said, the other projectors on the list all have their strengths.
I still wouldn’t post most of these images to Instagram, but I could see this being useful in very specific scenarios. Overall, we’d have to call it a draw between the GS III and either variant of the HTC One X, at least on the basis of these specific tests. It has to be at least 30 percent charged for this to work, though, and it takes awhile to juice up other gadgets. Well, that’s pretty great, at least when it works. The image stabilizing works well on all the neon lights that pepper Tokyo, while even people were neatly captured. Of course, we are all familiar with the trapezoidal “keystone effect”-the image appears wider at the top when the projector is too low, or wider on one side when the projector is horizontally off center. Contrast as viewed from the center position is only one of several factors that contribute to image quality and screen functionality. As far as image clarity is concerned, nothing beats it. The Da-lite Parallax 0.8 stood out as outstanding in this group in two particulars — clarity of the image, and extremely wide viewing angle. If you take the basic shape and concept, it’s the spitting image of the curved-screen Youm prototype spied at CES a little less than two years ago.
The Parallax 0.8 is an excellent choice for any application in which you need to have the image highly visible across a wide viewing space. If you are buying this for your baby or your niece or a kid, you need to go through the feature list. The EPV PolarStar has one commanding feature that no other ALR screen in this review has — it has a Silver-Gray surface that polarizes light, a feature you need if you want to set up a passive 3D video system. The one thing missing here is wireless charging, which still isn’t a standard feature on mid-range earbuds. Digital connections – today’s standard – are HDMI and DVI, which are considered the highest quality connections. Meanwhile the Da-lite. DNP both fell to 12:1. So if you want the highest contrast of the super-wide viewing angle screens, the DarkStar9 should be on your short list. The most notable limitation of the Supernova is that it is low in contrast and color saturation compared to the other screens in this review — it measured 16:1 contrast in the side illumination test, which was the lowest reading among the eleven, and just below the Da-Lite Parallax at 17:1. In any given ambient light situation with any given projector, black levels will not be as deep and color saturation is not as rich on either of these screens as they are on other ALR screens in this review.
