Acer SpatialLabs View 15.6-inch Glasses-Free 3D Portable Monitor Review

The Acer SpatialLabs View is a 15.6-inch portable monitor that displays 3D images without needing glasses.

Why you can trust Tom's Hardware Our expert reviewers spend hours testing and comparing products and services so you can choose the best for you. Find out more about how we test.

I’ve never reviewed anything like the View, so rather than comparison charts, I’ll just post the test results and comment on them. I ran the same benchmarks I would for any monitor using the 2D mode exclusively.

Pixel Response and Input Lag

Click here to read up on our pixel response and input lag testing procedures.

·  Response Time – 27ms

·  Absolute Input Lag – 61ms

The View is a 60 Hz monitor with fixed refresh and no overdrive. It draws the screen a tad faster than Acer’s claim of 30ms and has relatively low input lag for a 60 Hz display. This is not a panel for twitchy gaming or fast-paced shooters. Motion above a walking pace shows considerable blur, which is exacerbated in 3D by the 1920x1080 resolution. 2D images are 3840 x 2160 so blur is less noticeable there. But gaming with the View is better when the environment is one you’ll want to take time to explore rather than ripping through hordes of enemies in a frantic battle.

Viewing Angles

The View is an excellent example of IPS viewing angles with less than 10% light falloff to the sides and almost no color shift. If you stare at the photo above long enough, you’ll perceive a slight coolness in the horizontal shot. But gamma remains stable with all detail clearly visible at every brightness level. The vertical view goes red and dims by around 50% but retains good detail rendering. Note that these photos were taken in 2D mode.

Screen Uniformity

To learn how we measure screen uniformity, click here.

·  Screen Uniformity – Deviation From Center: 7.00%

The View has a high-quality panel with no visible glow or bleed in all-black test patterns. The extra optical layer added for 3D imagery does not affect 2D pictures. You’d never know the View differs from any premium IPS panel.

    Interesting, but I prefer the technology behind Looking Glass' light-field displays.

    They don't depend on eye-tracking and work with any number of viewers.

    As far as I can tell, 3D interest depends on how much people expect real life in 3D. My brother and my wife have a dominant eye and typically see in 2D, so they aren't impressed by 3D content ever. The fact that a good half of people could care less, really hurts adoption.

    However, availability of 3D displays that don't require much setup, or any classes, will help A LOT. That way the non-tech savvy folks can get into it. My parents have a 3D TV that I like a lot, but they can't manage to keep their glasses charged or sync'd with their TV consistently enough to be bothered with it.

    I consider myself something of a 3D enthusiast, in that I bought CrystalEyes LCD glasses for my PC, back in 1995, and bought a 3D plasma TV that I still sometimes use to watch 3D movies (I have a few dozen 3D blurays and trade them with another guy at work who collects them even more than I do). When there's a movie I want to see in a theater, I pretty much only watch in laser 3D (either I-Max or Dolby Vision). I even have a half dozen or more PS3 games that support 3D TVs.

    With all that being said, if I get engrossed in the movie, I find that I tend to forget I'm watching 3D and sometimes have to remind myself to pay attention to the eye candy. You just get used to it, I guess. From what I hear, a similar effect isn't uncommon among regular VR users.

    I think holographic displays have limited applications. Mostly either like 3D modeling, CAD, or GIS displays, where there's a practical benefit to seeing depth. For the general public, they're good for grabbing people's attention as they walk by some kind of kiosk or window display.

    I guess they'd make some pretty neat arcade games, though I'm not sure how much the arcade market even is, any more. Speaking of which, does anyone remember that 1991 Sega arcade game Time Traveler, with the dish reflector that made a planar image appear to be suspended in free space?

    Anyway, the major downsides of lightfield displays are that there's a bigger tradeoff vs. resolution, and they take a good deal of rendering horsepower, since you're essentially rendering the same scene from like 45 or 90 different angles. The pixel count is still whatever the display's native resolution, so we're talking about lots of geometry processing moreso than raster performance.

    That's where this Acer display comes out ahead. It has a much smaller resolution tradeoff, and lesser geometry burden.

    Light Field doesn't seem to be competing with 3D display's.

    They're more on their own track of novelty Displays that's trying to create volumetric Holograms IRL.

    Similar to what Star Wars & Star Trek has been wanting to do for many years.

    The way a lightfield display works is that you have to look at the display. Objects can appear to be in front or behind the plane of the display, but the frustum is clipped by the display itself.

    In other words, if you step too far to the left or right, you'll see the image cut off by the edge of the display. It's not as if they're projected into free space.

    Even that Sega arcade game only created the illusion of a display pane in free space. You still had to look into the parabolic reflector, even if you didn't realize you were.

    I saw the "Tested" video articles on LightField and how it slowly came to be.

    But I don't see them trying to compete directly against 3D Monitors.

    It feels like they're kind of going off in their own direction.

    The fact that they're not projecting into "Free Space" at the moment is a limitation of the tech.

    Everybody is trying to create the floating 3D hologram that Star Wars & Star Trek show us in their shows.

    As far as I'm aware, the only displays that appear to form fully 3D images in free space (i.e. with nothing behind them) are actually spinning a 1D or 2D display fast enough that you don't really notice it.

    They love to show those in science fiction (commonplace in the Marvel Universe too), but I don't think anyone has a decent idea to actually make one. For some Star Wars holograms, 2D projections on a medium work fine--like the R2-D2 type holograms that are low quality. Fantasmic at Disneyland basically looks the same and that might be achievable.

    The Light Field and 3D monitors both cost $1000 or so and provide glasses-free 3D. So they could compete. But I guess they don't because this Acer comes with all the software to make it usable as a computer monitor.

    The Looking Glass Portrait is $400, but it's rather small and their larger displays are way more expensive.

    What other Lightfield monitors are there?

    Looking Glass embeds a Raspberry Pi in theirs, which can play back prerecorded 3D movies in standalone mode. Or, you can connect and use it like a regular monitor.

    Oh, I explicitly meant those Lightfield ones that you mentioned (Looking Glass). There's no direct price comparison, but their small display price suggests that the price is similar for both technologies, within 50% of each other at least.

    I should look up some Looking Glass reviews. I like that the Acer one from this review was gaming-ready (well, 60 fps). I suppose I'd own both, if I just won the lottery.
