  • A peek at the back reveals a bevy of ports. First, the usual suspects: a headphone jack, SD card reader, four USB ports, and an ethernet jack.

  • The un-usual suspects? This iMac's sporting two Thunderbolt 3 ports. These support double the bandwidth of the previous generation—each of these ports can push data at 40 Gbps.

  • That's enough throughput to drive four 4K external monitors—although with this hardware configuration, Apple says we're limited to two.

  • How are we supposed to get by with a total of just three 4K displays? How?

  • Confirming our suspicion that this is mostly a 2015 iMac with a facelift, this unit sports the same model number (A1418), but with a new EMC: 3069.

一堆接口排列在背面。常客是:耳机插孔,SD卡读卡器,四个USB端口和以太网插孔。

新面孔便是 iMac 慷慨的2个全新Thunderbolt 3 端口。它们实现了同上一代相比两倍的带宽,它们每个的速率最高可达 40 Gbps。

如此高的数据吞吐量可以驾驭四台4K 外接显示器。但由于硬件配置,Apple 说我们只能外接两台显示器。

我们应该怎么做,来实现外接三个4K显示器的目标? 怎么做?

这台 iMac 几乎是旧瓶(2015款)装新酒,新 iMac 使用相同的型号(A1418),但用了新的电磁兼容性代码(EMC):3069。
