True black smearing in DK2

[equusvenustas]

After the EULA post, i started to browse treads in reddit and i found about this problem, i would like to know why it happens. It has to do with the AMOLED matrix? for example, the capacitor in the pixel circuit delaying the pixel due to charge time? or what is the reason of this problem.

Is the smearing only noticeable when you have quick changes from dark to light areas? I saw someone say the ReverendKyle tried Elite Dangerous with it and since much of the game is dark away from the stations, it wasn't as noticeable when you have dark gradients closer to one another.

I can imagine it being a problem when approaching space ports though.

Guess I'll find out next week. First game I'll try will be Elite Dangerous.

This is actually good to know early on since the prototype my friend and I are working will mostly be a dark scene.

It's strange, it's not just a clear answer where it happens. But most noticeably it is in pitch black areas. After doing the Totoro Bus demo, and looking up at the dark black night sky, it was HORRIBLE, the black smeared over the trees a whole lot, like a major shadow effect. In that situation, the trees were not that bright either...

I just don't get it. This would have been clearly noticeable in the Aliens demo and even the Swort Art Online demo.

Why does Oculus post more on reddit than they do here? It's honestly insulting.

I'm amazed that no staff have commented on this yet, this is pretty groundbreaking, even for developers.

How can they build an immersivee environment? take out the color black? bah, not having a bar of it.

Yeah really not for nothing this is kind of huge.

Or maybe they are aware how huge it is and there is nothing they can do about it, caught with their pants down and just don't know what to do.


Also yeah, why the hell do they all post on Reddit like it's their home? Wtf.

Oculus rep in Reddit just stated this.

We will have a fix for reducing this artifact. The artifact appears when a dark pixel becomes much brighter in the following frame. The green haze will not be necessary.

I'm thinking the SDK was rushed.

Seems strange the SDK was rushed, what with the community waiting so patiently an all lol

Would be grateful for a test with a plus RGB(0,0,1) instead of true black.

This issue isn't extremely critical from a development standpoint. It is certainly distracting from a player's perspective, but developers should be able to begin development regardless. A fix will be added to reduce this effect, and developers shouldn't have to change anything.

This is a known issue :roll:

If they fix this with software, they can give Sony a tip or 2. This was a HUGE issue when the PS Vita came out.

I, still, remember this quote:"*some* spots or abnormalities on an all-black or all-grey screen is normal. They are a byproduct of the manufacturing process for OLED, and it's very hard to mass-produce a large quantity of OLED screens without them."http://community.us.playstation.com/t5/PlayStation-General/An-important-note-about-the-OLED-screen-issues-black-spots/td-p/37156087

My Vita has a lot of spots when the screen's all black. I can't imagine what it looks like, magnified, in DK2. I would have NEVER approved OLED for a VR headset. At least, not with the current state of the screen issue.

Google 'OLED black spots'.

For CV1, the OLED and magnetometer have to go.

I imagine if the rumored partnership with Samsung is true then Samsung's expertise in new screen tech will probably fix this in CV1
