VGA to HDMI adapter suddenly not working

I got this old monitor a couple months ago and have been using it since with a vga to hdmi adapter cause my pc doesnt have a vga port. Then suddenly a couple days ago it stopped working so i figured the monitor died considering how old it is. However when
i got a replacement monitor which is also not particularly new but less old it still didnt work. I then tried connecting the monitor to a different pc that has a vga port and it worked fine. I bought the adapter only a couple of months ago so i dont know what
could have gone wrong.

 

VGA to HDMI adapter not working in Windows 10 - Vention adapter - Linux works

The adapter converts an aging HP laptop secondary display (vga) to HDMI so I do not have to switch my monitor back and forth. All other displays are HDMI. I picked the Vention adapter since it had the Amazon's Choice for "vga to hdmi" tag on it. It runs perfectly with Mint 20.2 out of the box. I assumed Windows would work but just re-booted into Windows 10. The secondary display shows up blank - it does flash a little HDMI pop-up from the monitor detecting mode change then shuts down as if no signal.

Windows 10 is up to date with all patches.

Secondary display does not show up in Device Manager.

Tried "Multiple Displays" setup and performed identify - no display on that channel. Main display shows "1|2". Detect does not find secondary display.

Removed HDMI cable from display - waited 10 seconds and plugged HDMI back in and it did not help - this usually works when HDMI EDID detection hangs.

Reboot does not help.

All this works fine with no adapter, just VGA cable and manually changing input on secondary monitor.

Anyway, my new dual monitor KVM switch works perfectly but this problem kinda defeats the KVM purpose. I was only switching KB+Mouse and using different monitor ports for different machines.

As I said before, this all (including vga-to-hdmi adapter) works perfectly on Mint 20.2 - a Ubuntu 20.2 derivative that "Just Works".

Thanks in advance for any suggestions to get the VGA-to_HDMI adapter work with Windows 10.

Any ideas?

 

Lumia Display Dock and HDMI to VGA adapter

just to understand some constraints:

• HDMI is electrically compatible with DVI
• DP outputs from most PCs have an HDMI compatibility mode that allows for:
  • DP-to-HDMI passive adapters [passive means it just uses wiring (no ICs) between the connectors]
  • DP-to-DVI passive adapters
• In contrast, the USB Type-C output on the Lumia 950XL/950 phone and the DP output on the Display Dock do not have HDMI compatibility mode. To drive HDMI, DVI (or VGA), they require active adapters incorporating bridge ICs. The tipoff is usually that such
  an adapter costs $20-$40 instead of ~$10 for a passive adapter. There’s no good way to tell active versus passive other than by part # and spec.
