Hey guys,

I have an annoying issue with my monitor. It is a 4K LG UltraGear OLED. (32GS95UV-B).

I have my monitor at 150% scaling as 100% is too small, now, when I turn the monitor off to say leave it downloading a game or whatever..and turn back on, the screen on the app (say EA app) will be small and disproportionate..

Is there anyway to sort this apart from closing out the app and reopening to bring it back to 150% scale?
 
This is probably due to Windows treating a monitor that's turned off the same as if it has been disconnected completely, and then moving everything onto its default no-existent display with 100% scale. Some apps don't like being rescaled like that.

I avoid that problem by letting the monitors go into standby instead of turning them off. They will still use a little power in that state, but negligible compared to a running PC. Of course there's no convenient button on a monitor to do that, so you have to wait for the 10 minutes or whatever that it takes before Windows puts monitors to sleep. You can force it to happen if you don't want to wait, by putting this in a .bat file and running it:

Code: 
powershell Start-Sleep -Seconds 1; (Add-Type '[DllImport(\"user32.dll\")]^public static extern int SendMessage(int hWnd, int hMsg, int wParam, int lParam);' -Name a -Pas)::SendMessage(-1,0x0112,0xF170,2)

thank you for this. i was considering leaving the monitor to be turned off, but my main display is a OLED, would this still be OK for this monitor?
 
Because you're worried about wearing it out? Standby is just as good as turning the monitor off in that respect, since all the pixels will be turned off either way.

perfect. one thing though, what about the idle period of 5-10 minutes?? without the image changing? would that make it more susceptible to burn-in?

Monitors Unboxed have done a 3 year test and burn-in isn't really a problem given adequate precautions.

 
strange..i tried putting my monitors to sleep after 5 minutes.. they went off, but after about 3-5 seconds they came back on themselves.. nothing touched?
 
That's windows sleep for you
Mine randomly came out of sleep for no apparent reason

Instead of turning off or putting my monitor to sleep (oled)
Now I just use a plain black wallpaper
And i have automatic hide desktop icons enabled
So a pure black screen which should mean no pixels lit up
Therefore no burn in worries
Not a perfect solution as still power to the monitor
Even if not using it
But the random coming out of sleep got very annoying

Those take effect when the PC itself is put to sleep. They don't affect putting just the monitors to sleep while the PC is still awake. When I've had problems with the monitors waking up, it has always been the mouse. Some mice don't track very well on some surfaces, and may think they have moved randomly even when they haven't. Or a mouse on a very slippery surface may actually move so easily that just breathing on it will wake the monitor. You can check if this is the cause by unplugging the mouse and then letting the monitor go to sleep.
