This is the complete LCD assembly for the iMac 27" Retina 5K late 2015 model.
See below for tape kit options for refitting the display
Please Note: The extremely high pixel density of these 5K displays can result in a slight image delay with fast moving images, and slight persistence of up to a few seconds when a screens objects are moved (when static for a period of time). This is normal and is not a fault. The more severe persistence fault known as Ghosting or Image Persistence results in much longer and more pronounced persistence.
These panels often have what looks like an image persistence issue, but it is in fact just slow response to image changes and it only lasts a few seconds at most.
This is a special listing to cover a common cosmetic aspect with this range. The edges of the LCD have a red hue. It is only typically noticeable on very light backgrounds, but image retention is more noticeable on these edges (typically with in 1-2 inches on all sides). This listing is graded as C-Grade accordingly. All other C-Grade defects would be covered under the normal C-Grade listing.
