The rendering pipeline does not lessen pixels used in the useable area of the screen, and as each HMD has a different FOV we can get a rough idea of the density of pixels and SDE in the upcoming headset by looking at the PPI of each headset relative to its diagonal screen size.
The fact is the Valve Index will likely have one of the least amount of SDE on any headset here’s why:ĭue to the fact Pimax headsets only render to 75-77% of the panel, I made the following graph with PPI measurements instead of PPD. It’s clear now, it’s an RGB 1600x1400 (3K combined) set of screens, not a Pentile 1600x1400 set which the vive pro offers. You might also be wondering why Valve Index chose to use such low resolution displays, I was too until I saw this thread. Well, Pimax magnifies it’s screens and only renders to three quarters of each screen, the lenses move to adjust IPD and a digitally rendered image moves across the screen in correspondence with the lens positions ( see video here).
Did you wonder about these images and why Pimax headsets offer comparable resolution to the Vive Pro and wonder, why does the XTAL have so much less SDE as the Pimax if the screen resolutions are the same? Pimax 5K+ is RGB LCD and so is XTAL, so why so much more SDE on Pimax?
