Suddenly out of no where a very thin red line has appeared vertically down the screen on my iMac, does any one know what it is or what has caused
? and can it be removed.
it is not under warranty, my iMac 21.5 inch 2017
The first post said it just started.
For any defect in a one-off purchase that becomes apparent within 1 year, it is assumed that it existed at that time of the sale, unless the supplier can prove otherwise. However, you can file a claim for a period of at least 2 years.
