At first I didn’t think this was a docking station issue, but now I think it must be.
I’ve had the same setup for over a year: external monitor connected to docking station via HDMI. Recently, the monitor has intermittently not displayed the output from the laptop, but manually selecting the HDMI source on the monitor has fixed this.
However, for the past few days, I can’t get the monitor to display anything from the laptop via HDMI.
I’ve tried the following, with no effect:
- Changing the HDMI cable
- Clicking the ‘Detect’ button in the display settings
- Bypassing the docking station and connecting the monitor directly to the laptop
- Checking Device Manager – display adapter drivers are up to date
Now here is the strange thing that makes me think this might be a docking station issue, despite point 3 above. I can get the signal to display on the monitor via its VGA port, direct from the laptop’s HDMI port through an adapter. I can then also get the HDMI connection working, via the docking station. But if I then unplug the HDMI cable from the laptop, the signal from the docking station is lost as well.
I’ve tried uninstalling the DisplayLink graphics driver, cleaning and reinstalling as detailed here: https://support.plugable.com/t/driver-removed-by-latest-windows-10-update/17386/2
Do you have any suggestions?
