The default environment can detect 3 monitors after bootup. And it works fine without a problem. However I notice if unplugging and then replugging the thunderbolt, it can only detect 2 monitors. The third one connected with HDMI would have message on screen saying something like "... in power saving ...". After running`disper -d auto -e` manually in terminal, the problem still remains - 2 monitors are detected and function correctly, but the third one is blank. The docking station is TB16, connecting to monitors with DP and HDMI .
xrandr produces output (not sure why monitors get auto detected are all DP after starting up)

Where to check the possible causes and messages, or how to fix this? Thanks
