In the present day HP revealed its next-gen WMR headset, Reverb G2. Whereas the unique Reverb beat out the competitors in decision, some facets of its show held it again from actually capitalizing on all these pixels. Reverb G2 brings with it model new shows and lenses which supply excellent readability.
‘Readability’ is a subjective time period which I exploit to attempt to boil down how sharp and clear the digital world appears by way of a VR headset. There’s every kind of issues that contribute or detract from readability. Decision is unquestionably vital, however so are issues like screen-door impact, mura, persistence, shade smearing, and lots extra contributed by the lenses. ‘Readability’ is the last word results of all of those components.
When aiming for optimum readability in a VR headset, any one of many aforementioned components could possibly be the bottleneck, so matching all these components is vital.
The unique Reverb clearly nonetheless has one of the best decision of any main client headset because of its 2,160 × 2,160 per-eye shows. And, arguably, it has the best readability too. And but Reverb G2, regardless of having the very same decision, has notably higher readability in comparison with Reverb G1.
However how do headsets with the identical decision, identical show dimension, and identical discipline of view supply totally different readability? Despite the fact that the widespread paper specs are the identical, the lenses and shows are totally different.Picture by Street to VR
Street to VR acquired an unique hands-on with a first-run prototype of the Reverb G2. I’m lucky sufficient to get early glimpses of hardware like this usually; on condition that issues can nonetheless change, I typically withhold agency judgements till seeing how the ultimate product shapes up. Even at this stage—the place some issues are nonetheless in flux—I’m assured in calling it Reverb G2 the king of readability.
Recapping Reverb G1
The G1 has a excessive pixel density, giving it extra resolving energy than another headset in its class. However the show and lenses had some points that have been in the end holding readability again.
Notably, the G1 shows had a perceived mura impact; that is comparable in look however wholly totally different in origin than the extra generally recognized screen-door impact (AKA SDE). Mura appears a bit like a faint, advantageous mesh protecting the lenses, or just like the show is a bit cloudy. On a cellphone or TV show, mura isn’t a lot of a priority as a result of the show doesn’t transfer together with your head. In a VR headset, mura—similar to SDE—is extra noticeable as a result of it strikes over the digital world as you progress your head.
Along with the mura on G1, the headset additionally had some shocking crimson smearing. This will solely be seen when transferring your head, however the impact causes any crimson colours within the picture drag or ‘ghost’ barely behind the opposite colours. That is exacerbated when the crimson is towards sure colours and with quick head motion.
And at last, Reverb G1 had a bit extra chromatic aberration (slight shade separation towards the perimeters of the lens) than I’d have anticipated. This wasn’t a significant factor in readability, however most headsets exhibit little or no chromatic aberration, and, as you possibly can think about, the higher aligned the sunshine is coming by way of the headset, the sharper the picture will seem.
I’m not bashing the G1 right here. It’s a stable headset that’s paved the way in decision and pixels per diploma within the newest wave of client VR headsets. Nevertheless it felt prefer it had some untapped potential in readability due to these show and lens bottlenecks.
Reverb G2 unlocks that potential by largely clearing up these points with new shows and new lenses.
The perceived mura has been almost eradicated, which alone makes a giant distinction. G1 was the primary client headset to successfully get rid of the screen-door impact because of its pixel density, however you couldn’t be blamed for not noticing as a result of mura took its place to a level. With the mura gone on G2, the headset is getting a extra ‘high quality’ out of its pixels.
(Despite the fact that SDE is successfully gone, that’s to not say that G2 has “retina decision;” you’ll nonetheless be capable to see aliasing at this decision. Eliminating SDE is totally different than reaching pixel density which meets the resolving energy of the human eye. Perhaps for G3—what do you say, HP?)
So, mura goes down and readability goes up. That is good. However what concerning the different stuff? So far as I’ve been capable of see, G2 has additionally eradicated the red-smear which is one other good win over the G1. Some chromatic aberration continues to be there, although HP tells me that the prototype I used to be testing hasn’t had a last calibration move, and it expects this may convey additional enhancements to chromatic aberration, and presumably another facets.Picture by Street to VR
HP additionally tells me that the redesigned G2 lenses (sure, they’re fresnel) have improved resolving energy in comparison with the G1, which additional enhances readability. You’ll be able to consider this a bit like ‘sharpening’ the pixels that you just’re seeing by way of the lens.
Like the unique Reverb, the shows in G2 are 90Hz LCD. Although HP says they’ve improved distinction and brightness. That improved brightness has additionally allowed them to decrease the persistence of the show (the period of time the show stays lit throughout every refresh). Decreasing persistence means the picture will look sharper throughout head motion.
One other win for G2 is a bodily IPD adjustment which ranges from 60mm to 68mm, which signifies that a broader vary of individuals will be capable to transfer the lenses into the best place to get essentially the most from the G2’s spectacular visuals.
Boiling all of this down, Reverb G2 is the king of readability, and I really feel assured that this would be the headset’s defining issue.
After I fired up Half-Life: Alyx, coming from Index, the G2 almost felt like wanting on the recreation with new eyes. I used to be drawn to particulars that by no means caught my consideration earlier than, like scratches within the shotgun’s steel, letters printed on the aspect of the pistol, and innocuous stickers protecting a gutter pipe. I additionally shortly observed that lots of the recreation’s textures don’t fairly maintain as much as G2’s decision (too quickly!).
After I pulled up Bigscreen to see what it was like to make use of my PC desktop by way of the headset, it was the primary time I didn’t shortly really feel bothered by the decision. The remaining bottleneck for doing typical PC productiveness work in VR with out compromise is now extra within the realm of, discipline of view, candy spot, and luxury.

And that’s actually simply the visuals of the headset. Past that, G2 brings a sweeping checklist of enhancements over G1 and different WMR headsets, like higher monitoring, controllers, ergonomics, audio, and extra, all of which we detailed in our Reverb G2 announcement article. HP additionally introduced that the G2 is offered for pre-order beginning at the moment priced at $600, with an anticipated launch date within the Fall.Picture by Street to VR
Clearly there was quite a bit to speak about with the G2’s visuals, so I’ll avoid wasting ideas on different elements of the headset for a future article. I’ll say now, nevertheless, that I haven’t but been capable of strive the brand new controllers. Past that, let me know what else you’d wish to know concerning the headset within the feedback under.
