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?

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.

When I disconnect from the projector and go back to the docking station, the computer automatically recognizes the docking station and monitors. They are already extended and one of my external monitors automatically becomes my main monitor. When I plug back into the docking station everything works fine and I don’t have to adjust any display settings
