It's not FOV that's needed for virtual monitors displaying readable text in VR, it's resolution. Not the flat panel resolution either... the only resolution that matters for VR and AR displays is Pixels Per Degree (PPD). This is because unlike a real monitor or TV, you can't back away from the monitor to increase the PPD. For VR and AR displays, the eye relief is constant, thus the PPD is fixed.
You need >35 PPD to read legible text on a displays. 62PPD is the maximum resolution of the typical human eye.
So, if you can get the company to advertise their PPD (doubtful, but some display providers do and are truthful), then you can answer your question.
- mojomark 4y agoThey actually advertise 28PPD on their site. That's actually not too bad, but still not very good for reading text on a virtual monitor. Note that that 35PPD spec comes from the equivalent PPD when viewing 12pt font on a physical standard 1280p 14" display monitor at a seated distance (eye relief) of 20" from the monitor. So, there's some subjectivity in that value. I guess if you're used to working in, say, 38pt font or so, the this 28PPD might be ok? (I didn't do the math)
- sudhirj 4y agoWhat's the PPD required for a "Retina" display (one at which individual pixels are no longer distinguishable)? Is that 62 or some other value?
- mojomark 4y agoThe Googles told me 60PPD (1): "If there is any single number that people point to for resolution, it is the 1 arcminute value that Apple uses to indicate a “Retina Display”. This number corresponds to around 300 PPI for a display that is at 10-12 inches from the eye. In other words, this is about 60 pixels per degree (PPD)." 1.) https://www.anandtech.com/show/7743/the-pixel-density-race-and-its-technical-merits https://www.anandtech.com/show/7743/the-pixel-density-race-a...
