Newly replaced hard drive, and now cannot connect my mac to hdmi port
I replaced my failing hard drive with a 3rd party hard drive because it had a better warranty than what I would've gotten through the apple store. I tried to hook up my laptop to my TV via HDMI port, and it won't recognize the screen like before. It shows the space background that was displayed when I replaced the hard drive instead of mirroring the screen with my current background, files etc.
Any help is appreciated!
MacBook, Mac OS X (10.7.5)
