Ask HN: Have anyone had success with projector-based work station?
4 by archibaldJ | 2 comments on Hacker News.
So I got a 4k projector recently (1920x1080 50Hz, ~$1700; positioned 2.5m away from a wall) I'm trying to see if I can be more productive using the projected display as the primary monitor where I write my code. Not sure if it's the burn-out or I'm just not used to big display, somehow even using it for writing text felt more exhausting for me (also maybe because it's further distance away so more effort is required as one types?). Have anyone had success with projector-based work station? Maybe it should be used as a secondary display instead? What's best set-up?
