So, two days ago I did a gig with the choral group I sing with. During setup, I took a fall and hurt myself, which is the excuse I'll used for this amateur mistake I made during setup We had almost no monitor feed during the show, which is unusual as I keep things well maintained and tested. Someone took a picture during the show to catch the reflection of the stain glass windows on the laptop. The next day I saw the picture online and also saw the answer to the problem! I could have smacked myself upside the head! Hint: It has nothing to do with settings.
