@liyunlong1123 #19 不是太懂，不过 HBR3 和 HBR2 数据传输效率似乎不太一样。
以常见的 Dell 2720QM 为例，开启 HBR3 可以用 usbtypec 驱动 4K 60Hz+USB Typec @ 8Bit 色彩
不要 USB3，可以开启 8 抖 10 的 10Bit 色彩
其中原理，包括 HBR3 我还没有系统学习过，请指教
TypeC to TypeC 走的也是 DP1.4 协议吧

@liyunlong1123 #17 但雷电 3 或者叫雷雳 3 吧，贷款是 40G，撇去给 DP1.4 用的带宽之后，还能剩下留给 USB3.0 的 5Gbps 带宽，普通 typec 带宽就不够了，普通 typec 不都是 4K60Hz 和 USB3.0 无法兼得的嘛

@liyunlong1123 #12 xdr 走的雷电 3 协议吧

@chouchen #1 不开发 Android 不知道什么程序带来的，装过两个安卓模拟器

@DoodleSit #15 感觉淘宝第三方便宜啊，也有定制机。 非定制版 PDD 最便宜了

入手价多少呀？

Early 2011 在家还能服役，当年 SandyBridge 的芯片。最高支持到 10.13 High Sierra
