HDMI2.0 DP1.2 DP是用TypeC转DP的
HDMI的固件在intel网站下载更新过了也不行
我购买了一个带双DP口的拓展坞 到货看看能不能解决双4K屏的问题

可以试试雷电口转双dp，感觉这样会稳定些。

试了 雷电口转双DP 还是雷电口转单DP外加菊花链再转一个DP后 都无法输出两个屏幕 均只有一个屏幕能显示 暂时没有找到稳定双4K的方案 可能目前唯一的方案是牺牲显示效果和延迟 透过采用displaylink的usb3.0 to 4k的转换芯片的扩展坞来实现

试试在 boot-args里面加上 igfxonln=1。

这似乎对我并不起作用。另外，据我查阅资料，雷电3转双DP是否支持双显示器输出取决于设备是否支持，故nuc8应该是不支持雷电3转双DP双显示器输出的
