Oculus Link and color range

[KarstenS80]

I've recently bought an Oculus Quest and I'm also owning a PSVR.

I have the game Moss on Playstation and in Steam.

As both devices uses OLED, there shouldn't be a huge difference in colors and brightness. But in real there is a really noticeable difference.

Playing Moss on PSVR, the darkness is darker and the brightness is brighter than on the Quest.

Yes, PSVR has RBG pattern instead of the penitle pattern of the Quest, but the difference shoul'd be that big and it also can't explain the difference in darkness.

Maybe there is some difference in the game. But I won't expect it to be.

As it is the same on both ends, brightness and darkness, I think it could be following:

For example in the NVIDIA coltrol panel you can setup a color range for your screen. Here you can change between full range and limited range output.

The difference ist:

Limited Range RGB 16-235
Full Range RGB 0-255

My point is: Moss on PSVR looks like full range and Moss on PC through Oculus Link to Oculus quest looks like limited range.

And the Question is: Is there currently a way to change it?

I've noticed this as well, blacks look dark grey and whites don't seem as bright and I guessed that somewhere along the way we're getting limited range, my best guess is if you want to mess with installing video codecs you may be able to change it there, or just wait for Oculus to fix it although if anyone has any other ideas I'm definetly open to hearing them

I'm sure it will be resolved as the beta continues on. We are early on in the process still. I'm sure the Oculus link performance now vs in 6 months will be drastically different.

I've now compared Moss again with the most current Versions. It seems that darkness got better in Oculus Link with V12. But in case of brightness the Quest is still noticeable behind PSVR, which could be of course caused by the difference between RGB OLED (PSVR) and Pentile OLED (Oculus Quest), as the RGB one has much more subpixels.

I tried to make some "though the lens" pictures.

To be compareable I've shot them as RAW with fixed values (iPhone X):



From worst to best:

Moss native on Oculus Quest



Moss on PC (Steam) with Oculus Link
The dark parts seems to be darker with V12 compared to V11?



Moss on PS4Pro with PSVR

I had the same issue on v11, they fixed this with v12

Comparing the Oculus Link connection to Virtual Desktop, Virtual Desktop
wins hands down..In the beginning, I was so used to Virtual D.
quality, that when I went to using the Oculus Link cable and noticed the
washed out high contrast version Steam side of it, thought it was
Steams fault. Turns out it is Oculus and their compression or settings
within Oculus. You would think they would have seen Steam through VD and
at least matched the quality. When looking
through Quest using Oculus Link, the Steam Home is very washed out,
contrast up, Gamma down. Wonder if FB Oculus
are working on that. Anyone else compare? Any possible way to tweak the
colors in Oculus Link side?

In the meantime I could get on the track of this problem. The default value of Encoding Resolution Width is far below the native display resolution. Therefore everything always looks blurred.

I changed this value in the Oculus Debug Tool to the maximum recommended value 2912 and now the picture is completely different.

The problem is: Depending on the graphics card, the rendering resolution in SteamVR has to be lowered for very hardware-hungry games. With Half-Life Alyx I have to go to 50% on my 1060. With games like Beat Saber you can go up to 200% on almost every graphics card and only then you can see in the Oculus debug tool what the display of the quest really does.

In the meantime, this has already been fixed. The display is now comparable to PSVR, although the luminosity remains behind, which should come from the PenTile Matrix.

Virtual Desktop is darker in appearance. In bright games this might look great, because the contrast will increase. But in dark areas all details disappear. Especially Half-Life Alyx does not fit with Virtual Desktop in my opinion. Dark areas lack contours too much. You miss a lot of the visual experience because you simply can't see anything.
