Hi, I made a post about this a while ago and it got moved to resolved issues, however the problem is still happening. Now it even happens despite not being on max graphics. Basically, my display goes black on both screens and the sound skips making a buzzing sound until I restart. I've only seen this happen in major cities, mostly Limsa Lominsa but occasionally Gridania.
