The Pimax keeps going into standby mode

Now, if you stay still for one minute while playing, it is very uncomfortable to enter standby mode.
I want to know how not to put on standby mode.
Why is there no setting that does not enter standby mode?
If you do not move 1 minute, you will be in standby mode, so you can not watch movies


I tried, but it doesn’t change…
I am using 8K, but the basic setting changes and the standby mode does not disappear.
