I'm using a Rift S headset and the accompanying VR Meditation program for a meditation study. For one of the conditions, I'm having participants watch the meditation on a computer screen while the headset is placed on a manikin head behind them. The headset is stationary throughout the 10-minute meditation, and this is causing the screen to blackout toward the end of the 10 minutes. This is disruptive to the study. Is there a way to alter the sleep settings or prevent the screen from blacking out?
