- it's helpful to have it be gigantic - bigger than a real monitor could ever be
- you have a real need for more monitors than would be practical to buy or position in your work environment
- you will be highly mobile and moving around so much that it's going to be better to take a headset with you than try to get monitors everwhere
- you really would like to collaborate with someone else who also has a Quest Pro, in which case you can work together without being physically together
- you highly benefit from / enjoy working in alternative environments (eg: being highly focused, free of distractions, relaxed, surrounded by beatiful scenery etc)
I actually find the latter point is the biggest reason I do it. Even when I'm surrounded by distractions I can go into a completely calm virtual environment and get a crap load of work done.
You can get something up and running - but it feels akin to staring at a 1080p screen with a weird delay. I felt way more productive just looking at my tiny laptop screen.
Your mileage may vary, obviously. I really liked the idea of working in a distraction free virtual environment, but I feel like the tech isn’t there yet unless you’re an enthusiast whose willing to put up with all of the strangeness.
So no, for most common uses this is nowhere near good enough. It's like having an old 720p LCD TV on your desk. It works for casual web browsing and movies, but far away from the image quality of a modern 4k monitor.
Nreal Air at around 49 pixel-per-degree is the closest thing to a monitor-replacement you can currently find, even has a plain HDMI input. Does however come with a lot of other short comings (no 6DOF tracking, monitor image not tracked, low FOV).
A few generations and it’ll be doable.
