I have two monitors, both of which were working prior to a recent move, and now neither of them show a (full) signal from the computers I've tried them on. They turn on, the menu ctrls work on one of them, but they say "no signal", or "check cable" or are just on but a black or greyish screen (other than brief flashes of color or a cursor, see below).
It's not a computer issue, because another monitor works fine on my two test computers. I've also tried seating the cords better, changing the inputs, nothing. Well, at one point for a few seconds I saw a cursor and a flash of blue but then it went to this dark grey (not quite black) state and one of them said "NO SIGNAL".
I'm so puzzled because it is BOTH of my old monitors at once, in exactly the same way. My only wild guesses as to what could be happening or happened is:
- Somehow "trauma" from the move broke them both just in this way. But they power on and at least one shows the menu controls, so it strikes me as very odd that slight jostling or very mild heat (moved May 1; temp was prob in the 60s-70s) would knock them both out in the exact same way--particularly in a way that just affects receiving inputs, not the actual display.
- I am maybe using the wrong power cord on both...but it fits and has no box, and they both turn on and display menu settings, etc., so I can't imagine it matters in this case.
Is there some other way to figure out what happened? They are like 21" or so HP and Coby monitors and worked just perfectly prior to the move, so this is pretty frustrating and I'm wondering whether I can resurrect them.
EDIT: Solved. Somehow, by trying my one monitor on a laptop and toggling the screen output and selecting a different "source" on the monitor, it eventually hit on the right combo and works now. Haven't tried the other monitor, but this is good enough for now. I knew they couldn't have both died in the same way.
