What viewer do you use?

I use Skybox VR Viewer. It works really well with movies on the headset or streamed from your PC over wifi.

I'll give that a go. I've been disappointed with some of the big-screen apps so far.

yeah, it works well and the default cinema setting is excellent. Also, the screen size is just right. I wonder why "Big Screen" and Netflix etc. find that a problem. The Achilles heel, is the same though, for me anyway. It's poor resolution. A grainy image. Maybe on an HP Reverb G2 it would be great, but there's an irritating lack of sharpness, even with 4k source video. If a phone is going to give a better image it's always going to be disappointing.

I don't have an issues with the resolution. maybe it is because I have 60 year-old eyes now.  :-(

I have 66 year-old eyes and getting older every day
