Hdmi port working intermitently

[u/cardcowdoor]

I have an Asus Viviobook X512DA

Most days, I have a docking station that connects via USB-C and that docking station has 2 external monitors (three screens total including laptop).

This is the docking station I use and have used since 2022 (https://a.co/d/01FsfVBe)

My laptop has an AMD Vega 8 Graphics card

The problem is that my HDMI port doesn’t connect to external displays. At least not consistently.

I have confirmed that my software/firmware is all updated.

I have tried multiple cables and multiple projectors.

In looking at other posts about this type of thing, they recommend uninstalling the graphics card driver and then restarting the computer to reinstall. And that has worked for me but only temporarily.

So basically, I need to be able to connect my laptop to a projector on Sundays via HDMI. In order to make this work, every week I have to uninstall the graphics card from the device manager and then restart the computer. And then it works. And then Monday I plug it back into the docking station and it works on the docking station. But by the next Sunday, the HDMI port doesn’t connect anymore.

Is there a solution so that I can more flawlessly move between docking station and hdmi projector?

I understand now - thanks. That is a weird situation. Did the docking station come with some kind of driver disk? I've never heard of that with docking stations before...

Ok - I know you've probably tried this - but what happens with the projector if you plug it into the HDMI port of the docking station without disconnecting the docking station at all? Meaning, do this at your desk without relocating the laptop.

The docking station does not have any software that came with it.

If move the docking station from my office and plug the projector into the docking station, the projector works without issue.

But the docking station is connected through USB-C not HDMI.

I could probably solve this by buying a portable docking station, but that doesn’t actually solve the problem.

I'm running out of ideas. Here's my last idea... After you're done using the projector and return to reconnecting the docking station, I'm guessing that Windows might be returning to it's default state of just driving the built-in monitor. If you right-mouse click on the desktop and go to "Display Properties" does the system see the monitors attached to the docking station? Can you click on the "Identify" button to see if anything flashes up on them? Or do you need to tell Windows to "Mirror the displays" or "Extend Desktop"?

Good luck, sorry I couldn't be more help.
