I just got a Thunderbolt to HDMI cable to plug my MBA directly into my TV (55" LG LED). I got it plugged in and everything looked great, quality wise. However, I noticed that the mirror display from my MBA was slightly larger than the TV display itself. I'd say it was about 1" too large all around. Is there any way to get the MBA mirror display to conform to my TV's display? I went into display settings and tinkered around with it a little bit. It's set to output 1080p, which is what my TV is. I didn't mess with anything too much beyond that. Thank you!
