It's not far worse. My display at home has 60% of the Li ear resolution of the AVP, the experience is terrible for productivity. I've tried displays that come very close at 80%, and it's still unusable for me. If the screens are reasonably size so that I don't have to move my neck all the time or suffer optical aberrations, like my real life screens, I get an effective resolution of ~720p.
We can see that this will be similar : the AVP has ~35 pixels per degree, my screens are about 45 degrees, so I can expect 1575 pixels across and 885 vertically, so just a tad better than 720p. In practice you'll lose significant resolution to optical aberrations unless your neck makes it point right there.
Who is using 24inch 720p displays in 2023? You can get at least a 1080p for like 20$ on classifieds and 100$ new.
This is sitting as close to the display as you ever should, btw. A 24inch screen will be 45 degrees wide if you're sitting less than 1 meter (36in) away from it.
This is an iteration on something that already exists. Probably won't be perfect, but it can and will be a monitor replacement for some.
