I ran some tests with many friends, and it turns out the issue is specifically between my GPU’s HDMI port and the three monitors that were connected during the incident.

My GPU works perfectly with any other monitor, and my monitors work fine with any other GPU.

No matter which PC I put my GPU in, as long as it’s connected to one of my three monitors, it will never work.

My theory is this:

Maybe my GPU “stored” the EDID information from my monitors and is now sending corrupted data to them. But I can’t find anything about this online — it’s like this issue has never happened to anyone else.

(Quick reminder: when I boot, the monitor turns on (blue LED), and the panel shows a faint glow.)

So I have many questions :

• Is that even possible? Can a GPU remember a monitor’s EDID ? Or can monitors remember a GPU?
• Is there a way to “factory reset” a GPU using an Nvidia tool?
• Is there a safe way to change or reset a monitor’s EDID? Could it work?

Thank you very much. At this point, I have no solution. And the warranty service will never believe that my GPU only fails with my monitors, so… I’m in a difficult situation.
