Have a Thinkpad connected to two identical displays via AJ40 dock. When running display-switch I get following logs:

19:33:30 [ERROR] Failed to get current input for display 'AUS PA278QV L8LMQS137232 #1': DDC/CI I2C error: Remote I/O error (os error 121)
19:33:30 [ERROR] Failed to get current input for display 'AUO #2': DDC/CI I2C error: Remote I/O error (os error 121)
19:33:30 [INFO] Display 'AUS PA278QV L8LMQS137232 #3' is currently set to DisplayPort1(0xf)
19:33:30 [INFO] Display 'AUS PA278QV L8LMQS137224 #4' is currently set to DisplayPort1(0xf)

Should my config look like this (ie both set as DisplayPort1)?:

usb_device = "usb:id"

[monitor1]
monitor_id = "L8LMQS137232"
on_usb_connect = "DisplayPort1"

[monitor2]
monitor_id = "L8LMQS137224"
on_usb_connect = "DisplayPort1"

Now it states no displays are found:
