How to Change Screen Resolution in Windows 10
One of the many change-it-once-and-forget-about-it options in Windows 10, screen resolution determines how much information Windows can cram onto your computer screen. Changing the resolution either shrinks everything to pack more stuff onscreen, or it enlarges everything at the expense of desktop real estate.
To find your most comfortable resolution — or if a program or game mutters something about you having to change your screen resolution or video mode — follow these steps:
Click the Start button, choose Settings, and click the System icon.
When the System page appears, click the words Advanced Display Settings in the bottom-right corner.
The Advanced Display Settings window appears, as shown.The higher the screen resolution, the more information Windows can squeeze onto your computer screen.
To change the screen resolution, click the Resolution drop-down list and select your desired resolution.
The drop-down menu lists a variety of resolutions, all sorted by number. The larger the numbers, the higher the resolution, and the more information Windows can pack onto your computer screen. Unfortunately, packing more information onto your screen shrinks the text and images.
Unless you have a good reason not to, choose the resolution with the word (Recommended) next to it. That’s the highest resolution your computer supports.
Choosing the Windows-recommended setting makes for the clearest text and images.
View your display changes by clicking the Apply button. Then click the Keep Changes button to authorize the change.
When Windows makes drastic changes to your display, it gives you 15 seconds to approve the change by clicking a Keep Changes button. If a technical glitch renders your screen unreadable, you won’t be able to see or click the onscreen button. After a few seconds, Windows notices that you didn’t approve, and it reverts to your original, viewable display settings.
Click OK when you’re done tweaking the display.
After you change your video resolution once, you’ll probably never return here unless you buy a new monitor or upgrade your computer’s video. You might also need to revisit this window if you plug a second computer screen into your PC.
