How to Find Out and Optimize Your Screen Resolution in Windows


Bloggers, especially those working with photographs and images, need to stay on top of their screen resolution settings. It is very important that their visitors see their images as intended and not somehow distorted. Therefore it is good to know how to find out and change your screen resolution in Windows, so that it’s optimized for your visitors.

Screen Resolution

To find out your screen resolution, right-click on your Desktop and select Screen resolution from the drop-down menu.

In the new window check the numbers next to Resolution:. This is your current screen resolution.

To change your resolution, click on the box right to Resolution: and select your new resolution on the slider.

The lower the resolution, the bigger all objects will seem on your display. And the higher the resolution, the smaller all objects will seem.

To save your new settings, click Apply.

Windows will show you the new visual of your new screen settings and will give you 15 seconds to make up your mind about it.

After that in the Do you want to keep these display settings? pop-up window, you can click either Keep settings or Revert to go back to your original settings.

If you click on Make text and other items larger or smaller in the Screen resolution window, you can achieve milder changes in your resolution. You can set your screen resolution to the maximum available on the slider and then select Medium – 125% in here. To save settings, click Apply.

But keep in mind that this distorts your understanding of how your visitors will see the photos you publish. If you are a professional photo blogger, it’s best to keep this setting at Smaller – 100% (default).

But What Do Those Numbers Mean?

Here is a simple explanation of what is happening with your display when you change its resolution.

The physical dimensions of a typical 17-inch display are as follows: width = 12.3 inches or 31.25 centimeters, height = 9 inches or 22.86 centimeters.

In case your display supports a resolution setting of 1920×1080, it means that there will be 1920 pixels displayed horizontally and 1080 pixels displayed vertically.


Display Dimensions

In liquid crystal displays (LCDs), a pixel is a physical point on the manufactured grid of the display. Each pixel has its specific location that can be programmatically addressed in order to display the right color at the right time.

The resolution you decide to go with determines the dimensions of a pixel.

If you go with 1920×1080, one pixel will be 0.0064 inches or 0.016 centimeters wide and 0.0083 inches or 0.021 centimeters high. These are actually the physical limits of a 17-inch LCD — the pixels cannot be any smaller.

On the other hand, if you go with a resolution of 1280×720, one pixel will be 0.0096 inches or 0.024 centimeters wide and 0.0125 inches or 0.031 centimeters high.

You can see, that as you lower the resolution of the display, the dimensions of a pixel rise. This is why all objects appear larger at smaller resolutions.
