Can putting an iMac on its 'side' damage its video quality?
So I bought an iMac 27inch 5K Retina 2015 version and I know the 'stand' attached to the computer won't be detached. I did an experiment and put my iMac on the side leaning on the wall so my iMac screen will be vertical(portrait mode). And then I watched something and it turned off after 30 seconds. I think it's because of the cooling problem but I also think turning on the iMac while it's put 'on its side' vertically can damage the video quality(I can kinda see it). Is it possible?? Please help.
iMac (Retina 5K, 27-inch, Late 2015), OS X El Capitan (10.11.1)
