NUOLAISUN iMac A2116 2019 EMC 3195 MRT32 MRT42 4K 21.5" Screen

iMac 21.5" 4K Retina replacement screen

This replacement panel fits the iMac A2116 2019 model with EMC 3195 and part numbers MRT32 or MRT42. It combines the LCD display and front glass cover with pre-applied adhesive in a single assembly. The part is supplied new and is intended for repair technicians who can verify compatibility before installation. Professional fitting is required because the screen is a fragile glass component and no instructions are included.

Repair technicians and experienced DIYers

Buyers who cannot confirm the exact back-panel label data should not order this part. The supplier notes that many screen models appear similar but are electrically incompatible, and returns caused by mismatched specifications are common. Anyone unwilling to disconnect the power adapter and battery cable during installation should seek professional service instead. Novice buyers without access to the original screen markings are advised to consult the seller before purchasing.

EMC 3195 and MRT32/MRT42 part-number match

The single specification that decides fit is the exact model identification on the original screen: EMC 3195 together with either MRT32 or MRT42. The supplier requires this data along with resolution, pin count and touch status before dispatch. If the numbers on the back of the old panel do not match these identifiers, the screen will not work. Always verify the label before ordering.
