Sound But no Display

My Pc is not registering the glasses. I’ve been using the glasses for a week soon after I bought it. Now it doesn’t work. I Keep good care of these glasses. I’ve done all the steps like resetting drivers and not using third party cables still no resolution. What am i suppose to do?!

Hi, have you ever tried to update the firmware of the glasses? If not, please try to do that. I attached the update page of Air 2/ 2 Pro.
