HP Reverb Redux

It’s very good, the same as wherever you look you can see at 1920x1080 resolution. So basically just what you see with a 27 inch 1080p display sat at about 3 feet.

Wowza… If I ever have the money that’s what I’d go after.
Thanks! :slight_smile:

If you have played Elite in VR and been a bit disappointed in ship fuzziness during battles or at the lack of fine detail shown in space stations, the Reverb solves all of that.

I really like your comparison of VR and flat screen displays. This is nice and easy way to get ballpark figure of the VR resolution capabilities. I found couple links that help comparing VR to any sized and resolution display at any viewing distance.

First a tool for analysing display PPD (Pixels Per Degree):
http://phrogz.net/tmp/ScreenDensityCalculator.html#find:density,pxW:1920,pxH:1080,size:27,sizeUnit:in,axis:diag,distance:3,distUnit:ft

Second link contains comparative PPD measurements calculated by someone at Reddit forums:
https://www.reddit.com/r/vive_vr/comments/bma93k/hp_reverb_cockpit_through_the_lens_im_sold/emxshsn/

In fact, those figures would put the Reverb resolution in line with 1920x1080 27" at little over less than 2 feet. Of course there may be some variations in FOV and how the image is projected on the VR display panel warped for the lenses.

I am also waiting for the Reverb to be delivered next week, so this is raising the expectations. I just hope I can live with the colors after O+ OLED goodness.

Edit: my example calculation above was flawed. If PPD and not subpixel PPD is used, we get Reverb PPD of 18.92 equivalent on 27" 1920x1080 at 0.8 feet distance. Now doubting if this is credible result at all.

Edit2: as pointed out later in this thread, the figures in second link are not credible enough to make comparisons.

Good links, thanks!

It’s interesting as my son plays a lot of VR himself but not really sat-down driving or flight sims (he loves real cars though). He tried the Reverb by immediately making a big play space and his first words were ‘Why is this cable so thick? Why don’t you have a play space set up in SteamVR?’

I replied, ‘But look at that clarity - amazing right?’ and as he whipped around in Superhot VR he said ‘Sure, I guess.’

The Reverb is sort of the TM Warthog HOTAS setup but for VR, in that others that see the price, and it sitting on the desk taking room, that don’t play sims will think it is sort of a bit crazy. :crazy_face:

There are lots of general downsides but what it specializes in makes it worth a look.

Have you noticed whether you can see the bottom of the LCD displays when you are wearing it? It is weird, because I saw the lines that were the bottom of the displays one time, but haven’t seen them since. I think it might have been before I adjusted it…I don’t have it crammed tight on my face. Some users have reported being able to see the bottom of the displays though. I generally wear small glasses when I’m playing, so I have a bit more distance between my eyes and the lenses just due to having the band a bit looser. I can’t wait to get those prescription inserts…

I’ve not noticed them, and will try not to now :slight_smile:

Hey, I’ve not tried IL-2 BoX - will do now. Forgot!

Ah yes, HOTAS bindings caused this (cough)

It is clear enough now that some of the textures look a bit low res. Great sim though, as a really nice framerate, so feels very smooth.

Beep beep.

I’m swamped with flying at work…but as soon as I have a few days off (3 more days)…we need to get some of us together and play Iron Wolf. I bought it in the Steam sale… :ship:

I guess most VR games are built with low res in mind and compensates for it.
I don’t think a high resolution will add anything to Superhot or Beat Saber, for instance.
But old geezers with deteriorating eyesight, who wants to read caution panels in vintage Swedish aircraft, will need those pixels…

I am sorry to say but the numbers are unfortunately misleading. Some time ago I made the same mistakes :stuck_out_tongue_winking_eye:

While it is easy to get some variables like hor / ver resolution, the FOV values (essential for PPD calculations) provided by manufacturers are all sorts of non-comparable: some are horizontal, some diagonal…

So when I made a comparison table, I decided to disregard officially published FOVs as well as user-measured FOVs (there are apps for that; though some users measure their wish rather than the reality :grinning:) and instead decided to use hor and ver FOVs rendered to the headset. So that is the maximum FOV sent to the screens. Now what is actually seen might be a different matter :face_with_raised_eyebrow: and other limitations apply too.

In short, look here for the results and methodology. I hope it helps.

So, this week I received a shipment with my old accessories (cable, controller). Interestingly it included my old, broken headset. This was for the better though, as my new headset was missing the earphones so I had to switch the ones from my old.

My first impression confirmed some of my initial impressions with the old Reverb. Subpar tracking, even with an overhead light, which include frequent “micro view shifts” and tracking failures when looking down into the cockpit panels. Also the new headset was displaying severe chromatic aberration (red/blue shift) in the periphery. I am still wondering why I am apparently the only one that sees this, as this is very apparent.

And now the best part! Also this new unit has overheat blackouts after about 30 minutes of use :smiley:

I am now going to request a refund and be done with it. I am happy for you guys that can enjoy the Reverb, but I think this is overall a crappy headset (even if it would work).

Sounds like you gave it a fair shake. I don’t blame you for reaching the ultimate frustration level with HP. Having gone through a bit of that with my first one, I can understand. That said, the Reverb is the best headset I’ve owned…

Sorry to hear of your continued issues. Sometimes things just don’t work out despite our best intentions.

I guess there are individual differences in the perception. I mean, for some the screen door effect was unbearable in the Rift CV1. I really had to look to see it. Others couldn’t unsee it after they was made aware of it…
And, color perception can vary a lot.
Perhaps a bit like this picture of a shoe. Don’t know if there’s any relevance to this case, but it is interesting…

Also, jog my memory. Did you try the Reverb on another computer?

No, I have never tried it on another machine.

To me, chromatic aberration seems to be a lense issue. The picture basically looks like this outside the sweetspot (on two different headsets):


Obviously that relativizes a lot of the supposed clarity due to superior resolution. I have an IPD of 64, so should be right in the middle of what the Headset is designed for.

This, together with the awful tracking, basically disqualify the Reverb for me even if it was working.

I also think some of us are less susceptible to visual acuity perceptions than others. I’ve worn glasses all my life, so I’m used to seeing frames, constrained field of view, and pupil swim and peripheral aberrations are just another day in the life. Just like some audiophiles are tuned to sound, some are just way more acutely aware of visual imperfections.

Yes. I’m saying maybe something with your visual perception makes it more obvious to you. At least, it seems like there are many different perceptions of the same issues, as for instance with screen door effect. It’s like when some people see more colors in the rainbow than others, for instance. Some people have better than 20/20 vision too.

Tracking issues and blackouts, on two headsets…
Have to make you wonder if it’s related to the PC, somehow.
Could the USB voltage be off?

Well, the blackouts are clearly heat related as putting the headset out of the window makes them go away.

Yeah, but couldn’t that be a voltage issue causing the heat buildup?
Just speculating, of course, but when both headsets have the same problem, the odds are it’s probably not the headset.
