Users want to be able to play flat-screen games inside VR headsets for longer sessions. Current headsets are often uncomfortable for more than an hour, and higher resolution would enhance the experience, making this use case more viable and appealing.
I personally don’t do it very often, but I definitely see the potential. In my case, since I already have a good TV and a solid monitor, I don’t really feel the need to play flat games inside a headset. On top of that, I usually play for long sessions, and wearing a headset for more than an hour isn’t comfortable for me. That said, I do think this use-case has a big future. As headsets become lighter, increase their resolution, and focus more on comfort (for example, devices like the Steam Frame, where you just plug a single USB into your PC), the potential gets really interesting. Do you prefer it over a regular monitor?
