So I’m really interested in 200 FOV and would be happy with the simpler version of the new Pimax HMD. (I will wait for 8K 90Hz until later even though I have a 1080ti videocard.)
So I saw the 5K version mentioned but no discussion, or even a forum channel about this. Is it a good alternative? Will it stretch 5K to 200 FOV, meaning it will have worse pixel density than the Pimax 4K?
Not necessarily. It may well be that the fill ratio on the 5K is better than on the 8K because it has lower physical resolution (PPI). And it’s almost certainly less screen door effect than any matching resolution OLED panel. However, I haven’t seen any current comparisons, so it’s largely rumour still.
PPI is one factor. Subpixel area and pattern are far more important to aliasing effects like SDE. Most OLEDs, but not all, are missing a full third of the subpixels, and those that remain are tiny. A microscope image showing a few pixels in focus is far more telling, for instance: https://www.google.com/search?tbm=isch&q=oled+microscope
Can you please confirm the numbers you’ve presented? Because first you said 5K is 490 PPI and then later you said 5K is 530 PPI.
Can you therefore verify these numbers:
PiMax 4K : 530 PPI
PiMax 5K : 490 PPI
PiMax 8K : 806 PPI
(these numbers are pixels per inches, therefore it shouldn’t matter if it’s stretched over the large FOV or if we’re talking about multiple panels - per inch means how many pixels are there if we take a random sample size of an inch anywhere)
If there’s a correction, please include it in your reply. Thank you.
