Severe Technical Issue

So long story short I just got a Pimax Chrystal Super and I wanted to try and play some H3VR like one does. Anyways I went to go change the graphics settings to ultra and now every time I load up the game mu whole screen is black on my headset but it still displays on my PC. Curiously though when I'm in the game when the screen is black and I click the menu button on my controller I can see in the game, buy when I un-pause it, it all goes black again... I can also hear the audio from the game the whole time. Someone please help :/
