Can't use USB-C dongle HDMI and internal HDMI ports simultaneously

Opened this issue 10 months ago · 3 comments

I can either use one or another, not the two at the same time.

Did anyone encounter this problem?

I have X280 and in manual We could read that

"Do not connect external displays to the USB-C connector and the HDMI connector at the same time.
Otherwise, only the external display connected to the USB-C connector I will work by default."

From what I've looked, there is no way to use 2 external monitors like this

I have 2 others T480 with W11, and I have no problems connecting two monitors like this.

Does 2K and 4K resolutions work over HDMI? And over USB-C?

I could not manage to make it work yet.
