Hey guys! I have a problem here that's driving me mad (and sad, of course). I'm trying to connect my Macbook Pro Mid 2012 with a thuderbolt to HDMI adapter to a monitor and my computer dont recognize it. I tried with a lot of cables, monitors and adapter and nothing works. The Mac only blink the screen when i connect it. The thing is: It works with a thunderbolt do VGA adapter normaly, i the same port! Can someone tell me whats going on? Many thanks!
