Deep Dive Overview
Retina 4K Display & Radeon Pro 560 Graphics
The centerpiece of this iMac is its brilliant 21.5-inch Retina 4K display. Operating at a resolution of 4096 × 2304 with support for one billion colors and 500 nits brightness, text appears laser-sharp and images show rich contrast. Paired with the upgraded AMD Radeon Pro 560 graphics card (equipped with 4GB of dedicated VRAM), this machine handles graphical tasks and video playback smoothly.
Factory Upgraded 16GB RAM Performance
While standard base-model iMacs from this generation included 8GB of memory, this configured-to-order (CTO) model features a full 16GB of DDR4 memory. This extra capacity prevents memory bottlenecks when switching between heavy productivity applications, streaming media, or working with multi-layered graphics files.
Quality Assurance & Testing Protocol
Prior to listing, this iMac underwent extensive diagnostic procedures. We verified display uniformity, port functionality (Thunderbolt 3, USB 3.0, Ethernet, headphone jack), speaker clarity, microphone capture, Wi-Fi/Bluetooth reliability, and wireless peripheral pairing.
The system has been completely erased, unlinked from previous Apple ID accounts, and pre-loaded with a fresh macOS installation so you can begin initial setup immediately upon powering on.
