If you’re on Windows 7, you won’t have the Settings app to go and will instead use the Control Panel app. The resolution you’ve selected will now be applied and you will have the usual option to revert to the previous one if you don’t like it. Select it here and click ‘Ok’ followed by ‘Apply’ on the properties window. This will open a new window listing every single resolution that your display can support. In the Adapter tab, click the ‘List all modes’ button. This will open the properties for the display adapter. Click Advanced Settings and scroll down to the very bottom of the advanced settings screen. Open the Settings app and go to the Display tab.

Windows 10 give you more options but if it isn’t listing the optimal resolution for a connected display, or it isn’t listing the one you want to use, here’s how you can add it. Back in Windows 7 you had one recommended setting and one really low setting for your display and you could select other settings on the resolution slider in Control Panel. Windows lets you select your display’s resolution from a reasonably long list of resolution settings that you can pick out.
