macbook air display is overflowing across screen
Hi. I have a 2014 macbook air with OS X Yosemite. I can't see the whole display. For example, I can only see one half of the notifications on the right, top corner. The rest are off them are hanging off the display, and I can't even close them. There's also a weird gray frame around the display.
I know the problem isn't the zoom setting on the accessibility settings. I've already checked that and ruled it out.
Any help is appreciated! Thanks.
MacBook Air, OS X Yosemite (10.10.2)
