how do you change its settings, like the aspect ratio, the dimming or the distance?

They have an OSD like in a regular monitor. You press the mode switch button twice to bring it and navigate using the ± brigness buttons. For dimming you hold the brightness rocker to start adjusting the dimming. For everything else there is an OSD menu like in a regular monitor. You bring it by double pressing the switch button and navigate with the brightness buttons.

how does it know where is forward in anchor mode? if you are sitting in a vehicle that is turning, can you keep it using as if nothing has happened?

It’s only 3 DoF without the eye add-on, so when you move, the monitor moves with you.

how do you do chores with it? I mean, what do you connect it to, and where do you place it so that it’s not in the way?

I just connect it to my Retroid Pocket Flip and put it into my pocket. Then I just enable side mode in the glasses, so it displays the image in the corner. And use my 8BitDo to navigate in the device.

what do you do to not get tangled in the cable, and to not get stuck on something?

The default cable is just very short :) It’s a distance from the glasses to my pocket with about extra 15-20 cm.

But it’s not VR. It’s basically an OLED monitor in front of my eyes. I can’t say it’s healthy, but I wouldn’t say it’s that bad.
