Help making pixel color change

[tarantules]

Hello.
I want to make a script that will scan the entire monitor aeria and find only the pixels that didn't change color for a specific time (i.e 10min) and turn it black or white for 1 or 2 seconds.
To help you better I want to prevent the image retention on OLED tv when I use it as a PC monitor.
Thanks

This would require you to have two huge arrays (millions of elements each) for both storing the color and time of last change for every pixel on your screen. It will be very slow loop through every pixel -- much longer than 10 minutes -- mainly because getting the pixel color is such a slow operation and there millions of pixels. Then you'd need to draw pixels in black or white on a transparent GUI covering the screen and keep track of the ones that were drawn (another huge array) so you can go erase them a couple seconds later, or just wait on each one, and at 2 seconds each that will make the process take a ton longer once it starts drawing pixels. It will take a lot of CPU time, and it would probably interfere (visually at least) with things a good bit.

You would be much better off just having a script black out (or white out) the screen for a couple of seconds every 10 minutes.

Even that it would be great and do the job...

This will alternate between a putting up a black window and white window that covers the screen every 10 minutes. It also moves the mouse so it doesn't show up when blacked (or whited) out, and then moves it back where it was.

Code: Select all

CoordMode, Mouse, Screen
Gui, -Caption

loop
{
	Sleep, 1000 * 60 * 10 ; 10 minutes
	MouseGetPos, MX, MY
	MouseMove, A_ScreenWidth, A_ScreenHeight, 0 ; move mouse off screen
	Gui, Color, % (Toggle := !Toggle ? "Black" : "White")
	Gui, Show, Maximize
	Sleep, 2000
	Gui, Hide
	MouseMove, MX, MY, 0 ; move mouse back
}
return

Edit: Correction to MouseMove speed

Thanks a lot for your help.This will do the work just fine.
Thanks again.

You're welcome. You might want to use the version that I just edited because I noticed I didn't put the 0 speed (fastest) on one of the MouseMove commands. Probably not even noticeable, though.
