I line on screen
I have just purchased an iMac 27 inch late 2012 but what I can't work out if it's the graphics GPU or the screen everything works perfectly but has one single thin line to the left. I have fixed so many of the old graphics cards on the magnetic removable front Imacs I've lost count.
I know the GPU is soldered on this particular brand.
But how do you work out if it's the screen or the graphics card image attached?
Thanks.
Ist dies eine gute Frage?
