How can I scale multiple screens?

Question

I am currently working on a Windows desktop and use Ubuntu at home. At work, I have 4 screens in total and 3 of them are different sizes.

Resolutions:

• screen one: 3000x2000
• screen two: 2560x1440
• screens three and four: 1920x1080

Why can't I scale one screen and not the others? If I don't scale I can't read anything on screen one, but if I scale everything is too big on screen three and four. I have tried different display managers, desktop environments and some differen distros.

Currently I am stuck in Windows because of this.

Make sure that the aspect ratio is 16:9 by going to System Settings → Devices → Display Resolution.

Note that the ratio 16:9 means full screen actually!
