In the past week, my Dell monitor has developed the habit of doing a factory
reset when the PC is booting up.

I wouldn't mind - but it gets it wrong and leaves the image shifted to the
right.

Doing the factory reset manually corrects it, but its a hassle.

I'm wondering if I clicked something I shouldn't have, or the monitor is on
its way out.

Its no biggie - I found the monitor in the first place, and since then
scrounged a better one on Freegle, I'd just like to know what's going on.

Thanks.
