About gaming in not-VR goggles

[Друг]

So I decided to not buy a meta quest or a bigscreen beyond cause one was just too much head equipment and the other was just too expensive, and then I decided to look for video goggles used in drones. I don’t want to play VR head tracking games, I just want a gaming monitor glued in front of my eyes so I can do stuff and play eventually. I got interested in buying the Walksnail Avatar Goggle X, which has an mini HDMI port along with 100hz and goes up to 100fps with both it’s FHD screens, but I have not found any video of people gaming in it, so I got some doubts.
1: Why people seem to not use video goggles as monitors?
2: Walksnail Avatar Goggle X is able to run gaming content without delay normally just out of the box? If I buy it I will be able to plug-and-play my setup without any problems?
3: Considering the aim for the least amount of head equipment volume and price in equilibrium, what kind of gear would you recomend? Remember I dont need head tracking VR.
Thx guys, godspeed
