Reverse screen colors

I have a problem, my phone screen now has inverted colors, in color negative, and I would like to know if there is a way to use a filter or an option to invert the colors like with the Windows magnifier but for the entire screen.

Hello.

I have a small problem with my MacBook; I can no longer invert the contrast using the usual keyboard shortcut that used to work just fine...
Does anyone know the issue?

Thanks.

I found a temporary solution, power strip.

I found a solution for those using Windows (tested on XP) with an NVIDIA graphics card.

I can finally rest my eyes...

- Go to the control panel;
- Then to the NVIDIA control panel;
- Go to: Select a task/Adjust desktop color settings/Choose the following color settings/tab "desktop."
- Modify the graphics as you like!

* In the graphics, set the left point at the top and the right point at the bottom to get inverted colors.
* If you want to keep the original colors of Windows, go to the slider, set: hue = 180°.
*To temporarily have inverted colors, keep the NVIDIA control panel open and hit cancel when you're done.

In the magnifying window, click on the parameter icon / minus 25° / and on the left set the display to 100°.

In case anyone is looking to invert the colors of Windows, simply use this simple, free, and lightweight tool: Negativescreen

Perfect for the visually impaired or to rest your eyes.

When you launch the magnifier, you can obtain this function but only on part of the screen.
Is there a way to apply this display to the entire screen?

up s'il vous plaît !

Same problem, please help me.
