I have been using the iMac Retina 5K 27″ (late 2014) for about 1.5 years.
Recently, I have noticed a tiny clump of dead pixels appearing on the retina 5K display panel, somewhere around the centre top portion. It’s definitely not dust nor stains, and the clarity of the dead pixels changes as you vary your viewing angle; it’s clearest when you view it straight on.
Apart from the dead pixels, there is also yellow discolouration or yellow banding along the border of the retina display. This phenomenon is similar to the reports on the screens of iPhone 5S where users saw some greenish-yellow banding/discolouration on their displays. From the photo I took of the display, the banding/discolouration is not very obvious, but there also seems to be some smudges or stretch marks in the lower corners.
From doing some searches online, I understand that Apple applies certain criteria (and here) when deciding whether a unit is fit for repair/servicing. The dead pixel clump definitely looks like more than 16 pixels to me so keeping fingers crossed here.
Fortunately, I bought an AppleCare Protection Plan just before the initial 1-year warranty period expired. Apple support suggested sending in the iMac Retina 5K to a Apple service centre and I will just be doing that after clearing up some backlog and doing a full backup. Hopefully, I can get the display exchanged as soon as possible with minimum downtime!
One of my favourites from our road trip to California. I still remember facing the cold howling wind on this evening at Baker Beach. I liked how they added nicely to the foreground texture. Upon reflection, I must have been pretty crazy to travel all the way here and position myself so close to the crashing waves. Needless to say, my equipment was drenched…
