You can get "high res" 800x480 glasses quite easily - because that's about the same as standard-definition (i.e. low res) old-style TV, and they all do that! (PAL ~= 720x576, NTSC ~= 720x480).

Personally I need them to look like monitors in ordinary use. So minimum 1920x1200 plus peripheral vision or overlaid onto real vision, please. Preferably several times that, so it looks like a regular monitor but placed over reality at appropriate places.

That's still out of range sadly. I look every couple of years. Impressions come across that military types might have access to some portable ones at monitor resolutions, though still not quite like thin spectables, and since that's your whole field of view, it's still quite far off usable as a regular computer overlaid on daily life, though maybe good for immersive AR/VR.
