I feel there's a lot of confusion around the resolution of a headset and the resolution of the video you're playing. When you're looking at a TV, the resolution of the TV and the video playing on it are usually 1:1. You're watching 1080p video on a 1080p tv screen and it totally makes sense. However in VR its different. If I watch a "4k" 360 degree video on a headset that has a "4k" screen, I'm actually just looking at a small section of that video at any given time. With the current Gear VR for example, if I watch an 8k 360 degree video, I'm not missing out on any of the quality, because it would actually take more than an 8k video in 360 degrees to give me a 1:1 view of the picture. I don't need an 8k HMD to appreciate that. The limitation right now isn't the resolution of the hmd (screen), its the resolution which the devices can actually play back reliably. That's how I understand it anyways.
