I would like to create a custom resolution on Windows 10, but I don't find the way to do it; on Windows 7 was simple, because I click on the right button on the desktop and there was "NVIDIA control panel" or something, and from here I could create a new. I've read that Windows 10 doesn't easily allow you to do this, is there a simple way to do it?
In Windows 10, go to Settings (Win+I) > System > Display > Scale and layout > Resolution. There is some list of resolution.
To find more resolution setting, Scroll down, click on Display adapter Properties. You can see this window (this may vary if your display driver is different).
From there select List All Modes. There you can find many other Resolution options.
There is also a 3rd party software to make custom Resolution setting:: MonitorTests:Custom Resolution Utility (CRU)
