我需要校准两个具有相同 EDID 的外接显示器（它们不是真正的显示器，它们是 2 个 BlackMagic Teranex Mini HDMI 到 SDI 12G，但它们被 Ubuntu 视为显示器）。
这是输出xrandr --props：

如您所见，HDMI-0 和 DP-0 具有相同的 EDID。eDP-1-1 是我笔记本电脑的屏幕。
这是现在的输出colormgr get-devices：

Colord 只看到两个 Teranex Mini 之一。结果，Ubuntu设置应用程序的“颜色”设置面板只列出了两个Teranex Mini之一，我无法将ICC配置文件设置为第二个。
有什么我可以做的吗？玩我的 xorg.conf 会解决问题吗？
编辑：我尝试编辑 EDID 并使用 edid-rw ( https://github.com/bulletmark/edid-rw ) 将其闪存到设备中，但没有成功。我猜设备的内存不可写。
