Well, it's been a lively day trying to fix the following issue: When I plug an HDMI to VGA adapter into the HDMI port of my Acer Nitro 5 (AN515-42) to connect to a VGA only Samsung S19B150 monitor, the display works fine for a minute, after which it develops a weird pattern that I can only describe as similar to waves on the surface of water, going horizontally across the display, after which the image promptly turns black, resumes the pattern, turns black, etc. The signal is constantly received however.
I have so far tried the following:
It could be that the HDMI port on the laptop may not be working properly, but that seems highly unlikely, the issue is that I have no HDMI devices to test the port on...
Another issue could be the adapter failing to sync the signal properly for this monitor specifically, but that as well seems unlikely given that it has worked for over a year with it without any issues...
Any other suggestions?
I have so far tried the following:
- Updating and rolling back display drivers
- Switching to known working VGA cables for the monitor, connected to another PC without an adapter - monitor works fine
- Testing the adapter on another setup, where it worked fine
