Looking at the impressions of the Berlin meet up, one of the things the 5k+ looks to have over the 8k is that its less blurry due to not having to upscale the image inside the headset. @deletedpimaxrep1 Will it be possible to fix this issue in the future with software updates?
Something I also wonder about:
Lets say a 1080p picture is upscaled to 4K. Let’s say every pixel becomes 4 pixels that way.
When you then move your head, does the image jump 2 pixels or 1? So, is the larger amount of pixels in the 8K also a contributing factor for smoother image movement?

That’s not the right way to think about it. You are looking at a 3D world. Moving your head will shift the world by some small amount, say a fraction of a degree. The image will shift by some small non-integer number of pixels, but will be redrawn as 2x2 pixel blocks, somewhat like the blocky areas used to obscure “private parts” in a video.
But on the pixel level will a side shift also shift per 2 pixels when a pixel is magnified from 1 or can the scaler work inbetween that because it knows it is scaling up?
I have the PImax 4K which also scales up and wondered about this but wasn’t able to really see what was happening due to the small SDE. So in any case, it’s not a problem but I just wonder if the scaler works smart like that or not
It doesn’t really work like that. The shift is in 3D space (fractions of pixels), which will then be drawn as 2x2 blocks. There will be “no inbetween” per se; the scaler in this case is limited to generating 2x2 blocks.
I believe the real question here is if we could disable unecessary pixels of the screen and (without upscaling) show only the pixels that the lens would “transport” the light to the eye.
If 30-40% of the screen pixels are wasted, maybe this could work. It would required just a portion of the screen at native resolution and thus a portion of the bandwidth.
You will need a specialized scaler for that, and all there is is the one they used. And that seems to be very limited in these types of possibilities. It has a few or maybe even one mode and that’s it
The 1.5x1.5 pixel blocks should prove discrete and fixed, but you’d not be panning discrete values from pixel to pixel. The rendering will cause pixel values to “crossfade” between neighbours.
@Pimel If the scaler has a limited scale factor, say a 2.5x scale of 1440p, it should be possible to change it if Pimax can get the manufacturer of the scaler to write a custom firmware for them.
Most scalers operate via software on chip, so if the manufacturer of the scaler can write a new firmware for the scaler, that could be a possible fix.
I can only say I’ve tested the same games back to back on 5 and 8, and I can’t say the 8 was in any way lacking details. For me it was smoother.
I’m pretty sure one of the reasons the Berlin responses are so different, is that every person tested something different. Different content with different settings. And the human brain has a hard time to objectively compare those memories.
I was lucky to wear all the headsets for 3 hours and visually didn’t find any reason, why the 5K+ should be superior to the 8K. But that’s just my brain, and maybe yours is different
God damn 3 hours?? I’ll probably stay with the 8k then lol. Was the 8k as sharp as the vive when you SS the vive at 2.0 btw? Or was it like when using the vive at 1.0 SS?
