I’m trying to make a youtube video go full screen on my secondary monitor, but it won’t work- it always switches to go full screen on my main iMac screen (and/or sometimes makes the other screen black and unusable). Could you please help?
Its not just youtube either- I just tried it with an Evernote window and it made it full screen on the secondary monitor, but it made the iMac screen completely black. Happens with all applications I think. I’ve searched online and it seems a lot of people have had this issue, but I can’t find a fix. How can I make full screen work right on second monitor?
