Hello! My old Macbook Pro display screen broke a couple of years ago (according to the tech guy there was a crack on the inside that caused the entire screen to go blank, and it was too expensive at the time). Just recently, I finally bought the HDMI connector cable for the Macbook so I could use it again, but I'm having trouble connecting it. The TV is an LG, and I bought an HDMI connector cable, and then the adapter for the Macbook. Once I plug everything in, the TV screen goes blank, and then the background to my desktop (the original/classic Macbook Pro background) shows up on the TV, as does the mouse arrow, but there are no files/menus visible. The mouse can clearly move off the TV screen so obviously there is a funky aspect ratio going on, but since I can't actually see anything on my Macbook I don't know how to go about fixing this. I have two HD TVs, and am going to try hooking it up to my larger, older flatscreen to see if it works at all. Any recommendations as to how to remedy this? Thank you for any help you can give me!!
