不是雷电协议本来就只能 4k 60 + usb2.0 吧

不是明明写了 3.1 吗……
DLC1293004RMG4RA3 这个是你的 a2119

AppleT6000USBXHCI 这个是你电脑…

@tanrenye 但凡看过 a2119 的 spec sheet 都不会说出这种话

3.1 hub 指的是那个 3.1 的 type A
2.0 hub 指的是那个只能充电的 type c 口

@acoldfox 190 有包装，说是 99 新，看包装像是 95 新

@tanrenye 这个应该不至于，雷电 4 带宽最高 40Gbps 4k60hz 才占 12Gbps 理论上还可以挂 5 个 usb3.0

@234ygg @20015jjw 感谢，明白了。

@zocome 官方入的少操些心，这些数据都是可以烧录的，我只是看下有没有录错。

@yy1193889747 4k 60hz 理论上占用 18G ，另外这款拓展应该不是雷电芯片吧，估计是苹果做了压缩之类的，我看官网，这个拓展，只支持有 4 个雷电口的 MacBook 输出 4k 60hz ，有点奇怪

@tanrenye
A2119 走的是 DP1.4
不支持部分机型是因为当时核显带不动

@tanrenye A2119 是走 USB-C, 但并不影响什么. 4K@60 输出还是没有什么问题的, USB-C 给力的话甚至可以承载 5K 或 6K@60 (例如 RTX GPU 带 Pro Display XDR. 当然, 可能经过压缩).
不支持部分机型是因为部分核显 /独显版本不够.
