would any of you guys know how to cure my monitor from going off after approx 10seconds?
It's a pain in the proverbial, as I will be in the middle of something and it will go off unless I'm using the mouse.
If i go away from it for a minute or so, I have to "Start" again :'(
The monitor is an AOC 23inch and approx 9 years old.

Normally I would have said PSU issue with your VDU switching off after 10 secs but the "unless I'am using the mouse" statement is confusing ?
I'am assuming you have not changed any of the VDU settings recently, even then, I don't think that you would be likely to set the "inactivity sleep" timer to 10 seconds, again assuming the VDU has such a feature.
If your VDU has a separate PSU try substituting that if possible with a unit of similar voltage/power rating with a similar connector of the same polarity.
If the VDU PSU is integral then your only option is to get inside the casing and look for any obvious, faulty components such as leaking or swollen electrolytic capacitors.
I had exactly the same issue recently with a much younger Samsung VDU, just out of warranty of course !
This had an external PSU which I was able to directly substitute, like for like, unfortunately that did not cure.
Did manage to open the VDU but could not see any obvious component failures, no joy, had to scrap.
9 years is quite a long life for a modern, "economy" electrolyitic capacitor, the component that is most likely to age and fail most quickly.

Try a different monitor cable. Also try resetting the monitor back to factory defaults.
When it goes blank what is the LED indicator on the monitor doing? When it goes blank get a torch and shine it into the display, can you see the stuff in the display still there? This would indicate a back light issue.
The oddity is why moving the mouse makes a difference and so might point to software/settings on your computer turning off the monitor after a very short time of inaction.
You could try disconnecting the computer from the monitor and then going into the monitors set up menus, does it still go off after 10 seconds?

There's two oddities "unless I'am using the mouse" and "start again"
Not sure if Bob is using Windows 10, but the shortest option for turning off the display is 1 minute (perhaps it would be worth adjusting this in power options in case the setting is corrupted or something), and if the display did turn off he wouldn't need to start again, a simple wiggle of the mouse should wake the screen back up and everything should still be there.
So I wonder if there is something else going on?
I have two monitors at work, every now and again one will go off, I suspect that's some sort of power issue, as everything shifts to the other monitor, but there's no starting again, just have to move the windows back across when it comes back on. Although that has got me thinking as to what would happen if I only had one monitor???

You say that using the mouse prevents the monitor from going off. Does using the keyboard keep it awake too?

Yes, win 10 home.
Yes, I do wiggle the mouse to wake it up, but it's frustrating when halfway through something and it goes blank/black.
I think the monitor is probably had it's day :'(

TBO, I haven't tried the keyboard, I will next time.
RIP my monitor. Thanks for helping guys,

If moving the mouse keeps it working, it seems unlikely its a monitor problem IMO.

Second that or at least, not a monitor fault (as opposed to problem).
As I think has been mentioned in this thread, I’d be looking at inactivity/sleep timeouts. Noting that such timeouts may be configured on the monitor, or the Operating System, or both.
-
Yes, I'd like to get into the OSD settings, but I cannot get it up properly.
To explain (If I can) I touch the button to bring up the menu (Brightness, colour, settings etc), then I can scroll up & down with the arrows.
Then select settings or whatever, but there appears to be no way of scrolling across to see what I might be able to do ???
I hope that makes sense?

If it's like my monitors you press the button to get the OSD, then use the up and down buttons to select the item and then press the first button again to enter the selected item.
Have you read the monitors manual? (when all else fails RTFM!)
-
I live in a Microsoft-free environment and so cannot try this. But the following link might describe how to reach the OS settings at least...
https://support.microsoft.com/en-us/help/4027067/windows-10-how-to-adjust-power-and-sleep-settings
I have sometimes come across well-intentioned, but misguided, ‘save the planet’ suggestions that might lead to power/sleep being accidentally messed up.

Yes, I did exactly that (pressed the first button again) but the OSD just disappeared. ::)

Thank you, I will check it out when time allows :)

Oops, quote meant for you ::)

Microsoft's default screen blank timeout is 10 mins. Found in Settings - Power. Can be set to never.

I'm not aware of timeouts being configured on the monitor, as the monitor has no clue when the PC is active or not.

The OS can’t properly implement it either, as it does not reliably know whether the human operator is actually looking at the screen, even if he or she has not moved the mouse for a while. :)

Very true, I've always turned it off. Even the Xbox One has a flawed implementation where it dims the screen during in-game cut scenes.
My OLED TV in fact DOES have its own feature to dim the screen when a static image is displayed to avoid burn in. Mostly it does a surprisingly good job, but I have noticed it falsely kick in on some YouTube videos where its just someone sat talking with a static background. I don't think its ever falsely triggered when displaying my PC though, it seems to realise quite quickly when I've moved the mouse and if its a genuinely static screen you don't need maximum brightness anyway.
For OLED its absolutely essential and clearly works, I've foolishly left static screens on loads of times over the past year and no visible issues yet. (touch wood)

The challenge on iMacs is working out what state it is really in.
There’s a screensaver timeout then, as you’d expect, an idle timeout, after which the screen goes off altogether. It still consumes quite a bit of power but after a further timeout the whole system should hibernate, consuming nearly no power.
Unfortunately there are many bugs and features that prevent hibernation from happening, and no status lights to tell you the difference between ‘screen off’ and actual hibernate. The only way to tell is to plug it in via a wattmeter, then wait a while before checking to see if it’s dropped to zero-ish. Mine generally needs a fair bit of quite difficult meddling, each OS update often undoing my efforts.
I’m generally a fan of Apple, and by no means a climate warrior. But I disapprove strongly that an awful lot of iMacs may waste an awful lot of energy in this way, the owners having no idea whatsoever there is any problem. :(

Speaking of weird, my desktop PC used to consume MORE power turned off than in sleep mode.
I can only assume it was some weird issue with what rails on the PSU it was using and perhaps 5VSB being super inefficient compared to the main rails.

Update...
I found my old 19" monitor, and have added it to the problematic 24" one.
They both appear to be working as should now. :fingers:
No Idea why that should be?

Maybe it was lonely? :lol:

love it :D
