vertical line across the screen.
I have a late 2013 27" iMac. I was browsing the web when all of a sudden a purple vertical line appeared on the screen. I thought it was the browser, but it's accross all apps. Tried rebooting, doesn't get rid of the problem. I tried to take a screenshot to post here, but the line doesn't show up in the screenshot. I took a picture of it with my phone instead.
I'm a month and half away from the 1 year purchase date. Do I need to contact the store or Apple directly?
iMac, OS X Yosemite (10.10.5)
