Unable to connect the Apple Thunderbolt Display and HDMI display simultaneously

Shark · 09-25-2025, 09:07 AM

Hi, I have a MacBook Pro (2022) with the M2 chip running macOS 15.6.1 (24G90). I am using DisplayLink version 14 along with two external displays:

1- Apple Thunderbolt Display

2- Dell display via HDMI

I also use a Satechi USB-C connection hub.

When I connect the Thunderbolt Display directly to the Mac using an Apple USB-C adapter, it works fine as a single external display. However, when I connect the Dell display through the HDMI port on the Satechi hub, it is not detected by DisplayLink.

If I disconnect the Thunderbolt Display, the Dell monitor is detected. But once I reconnect the Thunderbolt Display, it fails to detect it again. It appears that the system only supports one external monitor at a time.

Could you please advise on how I might resolve this issue?

Regards

Shark
