Monitor going bad?

LCD monitor started when I'd start using the PC while screensaved, to blank the screen and display the 'HDMI' message then return to normal.

After a couple days of that, now it's just stopped working at all, until I power the monitor off and on. Any ideas other than 'it's going bad'?
 
Oh, one other detail, the power on/off button on the monitor doesn't shur it off during this, I have to plug and unplug the power cable. But after the monitor is working, the power off/on button works.
 
The only input selection I see on the monitor is for picking an input like HDMI or auto select, it's on auto select which seems right.

It has a second menu section named HDMI but it's not clear how to get to it with the limited buttons of '1', up, down, and one I can't read the label but seems to be '2'.
 
Honestly, this sounds like the AMD "monitor wake / black screen bug". It seems like it needs the monitor to fully reset the HDMI hand-shake (by unplugging it), and plugging it back in, to trigger a re-detect.

Assuming that you're using HDMI, try moving the mouse, unplugging the cable from the PC and plugging it back in, does it come back then? If so, that's likely to be a video card / driver problem.

Didn't you have some video card issues before? Cards not installing the drivers correctly, or detecting correctly, or something?

Maybe you're right. The problem got worse. I don't recall the exact steps, but basically it wouldn't restart at all, even when I'd take the power cable on and off. Restarting the PC didn't help either.

It was sort of showing it was connected - when I stopped the screensaver, it showed the screen contents a second, and then went black. But then it would go to 'no video signal' and stay there.

Not everyone has all this crap, but I had a second PC hooked up to it by VGA; I had a spare HDMI cable; and I even have a new monitor, a 34" I bought 18 months ago and never hooked up. Let's get started.

Unplugging the second PC, no effect, and it wouldn't work on the second PC either. Really looking like a bad monitor. Switched out the HDMI cable just in case - nothing.

So, finally, I unpacked the new monitor and hooked it up - other than standing on a 6" elevated base so it's too high, working like a charm. So I conclude unless it was that bug you mentioned and unplugging the HDMI cable would have reset it, that the monitor is bad. Time for this new, really bright, 34". Man it's wide.
