[SOLVED] How to make 2 monitors display the same thing

[otryx]

Lets say i have a 4k monitor and a 1080p monitor. I am drawing on photoshop and the paper is 4k big, obviously the 1080p cant display the full picture but i want it that way so i can work on minor details and fix the drawing. But i want my other 4k monitor to display the full picture real time. So basically what im saying is how can i make it so my other monitor display the same thing as my other one but just bigger

Go in your Windows monitor settings and instead of using "extend" use "duplicate".
