HLVR is coming! I can feel it in my VR blood!  

Index + HLVR = win/win 🙂

Thank you Valve and thank you Boneworks! haha

Lol, with Valve I'll believe anything - when I see it  😄

Although the evidence is circumstantial, maybe the plot just thickened... Hmmmm.... HLVR?

I'm not even going to bother watching the video, they've been claiming that Half Life 3 is on the way for YEARS lol  😄

Exciting new Index stuff! (I put some text in bold  B) )

Index brightness, blackpoint and gamut measurements

Gamut measurements show coverage of :
  • 99.4% sRGB

  • 87.7% DCI-P3

  • 66% Rec. 2020

for reference, Vive is:

  • 100% sRGB

  • 97.4% DCI-P3

  • 75.63% Rec. 2020

Luminance in nits:

  • Index: 95

  • Vive Pro: 143 *

  • Vive: 214

Black level in nits:

  • Index: 0.153

  • Vive: 0.000 ? with true blacks turned off via black smear compensation (default).*

  • Vive: 0 ? with true blacks turned on, black smear compensation disabled via running the headset in secondary display mode.


So much for OLED blacks not being that much deeper anyways due to black smear compensation. Turns out that even with the compensation, where dark-greyness of black is visible to the eye, OLED headset blacks are still several orders of magnitude darker, so much so that xrite i1Display Pro can't display enough digits to distinguish it from true black.


In practice, having both Index and Vive Pro at my disposal, I personally prefer playing HellBlade with Vive Pro, due to how dark that game is. I wouldn't say blacks are dealbreakingly bad, but they're something to be aware of.

In short even with the dreaded OLED mura (SPUD) the OLED panels win big time over Index LCD when it comes to true blacks. And it seems that OLED also wins in other categories. Note especially luminance in nits, where Vive is more than 100 % higher than Index. Still Index may have the advantage of more subpixels, especially compared to the CV1. 

Kinda supports my decision of trying to have both CV1 and Index connected to the same rig - in case I need to surround myself with some real darkness (or the Odyssey+ may be great too, it's also OLED).


Seems that no matter how you try to replace the CV1 you end up having to compare serious losses vs. gains.

Yea that's not surprising to me. It's been covered with the Rift-S discussions but I haven't seen any LCD panel yet that's on par with my Odyssey+/OLED blacks or colors so I never thought it would be. My hope is that with some calibration and settings adjustment that it's good enough to not be distracting like the Pimax 5k which is more gray than black but I won't know until I see it for myself.

If you're only buying a headset for the black levels then it's going to come up short for sure. I might keep my O+ around for a couple of games and get it working with Knuckles.

Glad I went for the Rift S instead of the Index now, I didn't get any nits with mine as far as I can tell. Or maybe they can't live in my hair because my hair is so short?

Bloody gross anyway, they shouldn't be allowed to sell something you wear on your head that's bloody infested. 😮

BTW, I'm not that worried about black levels on the Index - I'm more interested in the 120 and 144 Hz - and Boneworks is starting to look really cool  B)
