This script so far seems to work, it displayed the message I want when the game is out of VR mode. The problem I have is that im not sure if the text will appear when VR mode is enabled as I do not have access to a VR headset at the moment. Will this work, its quite simple but ive messed up simpler before.
This is a local script as well.
while true do
wait()
if game.VRService.VREnabled == true then
script.Parent.Enabled = false
else
script.Parent.Enabled = true
end
end
Also if there is a way to enable VR mode without a headset that would be helpful as well.

I may be able to test this in a few days.
Try changing VRService to like desktop and see if it works then add the VR back
