Your Oculus Quest 2s resolution isnt as high as you think, but that's not a problem

Description:
Meta has revealed that the screen resolution of its Quest 2 headsets isn't as high as we thought, but it's the pixel-per-degrees that matter.

FULL STORY ======================================================================

While giving a talk at Display Week 2022 Meta display engineer, Cheon Hong Kim, revealed several details about the Meta Quest 2 ( formerly Oculus Quest
2 ), including that its resolution isnt quite what weve thought it was.

The Quest 2 uses a 1920 x 1832 resolution display for each eye, but because
of its lenses, thats not the resolution we actually see (via UploadVR ). For starters, the lenses are circular whereas the screen is rectangular, so the corners are cut off and Meta has literally cut the corners off the displays to remove unnecessary bulk.

On top of this, as you toggle the lenses between their three IPD settings which changes how far apart they are the section of the screen that can be seen through them also changes.

When the lenses are closest to each other, the outermost parts of the screen wont be visible, and vice versa when the lenses are pushed to their furthest apart. To save on processing and battery power, these invisible parts of the display arent activated.

However, as Meta goes on to explain, the fact that we arent seeing the
screens full resolution isnt really a problem. It's not the resolution of the display that matters but its pixel density. Through the screen door

One problem with VR headsets is something called the screen door effect. Because displays use an array of pixels in a repeating pattern it's possible to notice lines in the image an effect that makes it feel like youre looking through a screen door especially when youre right up close to them.

While this effect can never be entirely eliminated, it can be made much less noticeable by improving a screens pixel density. With pixels more tightly packed together in the same area, the gaps become much less noticeable.

As such, Meta aims to use high-pixel-per-inch displays and foveation technologies to steadily push pixel-per-degree counts beyond 60PPD (the limit that humans can perceive).

Based on current rumors, Project Cambria is expected to use new 2.48-inch
mini LED displays with 2160 x 2160 pixels per eye. This should bring the new headsets pixel-per-inch up to 1230PPI compared to the Quest 2s 773PPI.

To work out Cambrias pixel-per-degree wed need to know its focal length which we dont but assuming its the same as the Quest 2s wed be looking at a PPD of 33. That would still be a fair distance from the target of 60PPD, but significantly closer than the Quest 2s 21PPD.

That being said, there's a strong chance that Project Cambria will have a
more compact design based on what Meta has said, and so its focal length will likely be different. So, as with all speculation, we'll have to wait and see what Meta officially announces.

However, improving the quality of its displays is clearly a top priority for Meta so expect to see plenty of improvements when Cambria and its future headsets (like the Meta Quest 3 ) launch. Looking for something to play? Here are the best Quest 2 games we've tested
