Screen Resolution – Display Resolution, which is the number of pixels displayed on the screen. Setting screen resolutions is extremely important, so you can display sharper content.

On Windows 7 and Windows 8, monitor resolution is pretty straightforward. By default on Windows 10/8/7, you can choose to set display resolution screen, refresh rate and color according to your screen.

Flat screen LCDs are also commonly used today. Compared to the CRT, the LCD screen is thinner and lighter. Laptop also uses flat panel.

For LCD monitors and CRT monitors, the DPI (dots per inch) index is a problem, it will improve resolution and image clarity. The resolution you use depends on the screen resolution supported. If high resolution, such as 1900 x 1200 pixels, items will display sharper and smaller resolutions, so you can save space on the screen.

If the resolution is low, assuming 800 x 600 pixels, the items displayed on the screen are less and the space on the screen saves less.

Windows allows you to increase or decrease the size of text and other items on the screen while still optimizing the size and resolution of that item on the screen.

How to set the resolution of Windows 10 with different screens

When you connect the second monitor to your PC, Windows 10 automatically sets that screen resolution to the resolution of the main screen. If both screens have the same resolution, this is not a problem.

However, if one of them has a higher resolution than the other, it is a problem. If you do not handle the resolution for both monitors, there will definitely be a very bad image display. Besides, you also can not make the most of the resolution power of either screen.

Windows 10 allows you to set different resolutions for different screens. The problem is that doing this is not easy. On Windows 10, Microsoft removed the Wallpaper and Display settings from the Control Panel application, and moved them to the new Settings app.

The Settings app is a simplified version of the basic settings, but it complicates setting up multi-monitor resolutions.

In order for different monitors to have different resolutions, you must follow the steps listed by AddictiveTips below:

Connect the second or third monitor to a PC or laptop. Turn it on and wait for your Desktop or Extend or Mirror to the new screen you just added. Once you’ve connected the screens, it’s time to adjust the resolution.

Open the Settings application and navigate to the System Setup group.

Select the Display tab and make sure that Windows 10 recognizes all the connected monitors. Click the Identify button at the bottom of the Customize your display pane . This will help you distinguish which screen is screen 1 and which screen is screen 2.

Next, also at the Display tab , scroll down and click the Advanced display settings button.

On the Advanced display settings screen, select the monitor you want to change the resolution. You know what screen is screen 1 and what screen is screen 2 in the first step. However, if you skip that step, you can click the Identify button at this screen to identify your screens.

Select the screen you want to set the resolution to the other screen left. This is an important step because the resolution options at the Resolution drop-down menu will vary depending on the screen you selected. In the screenshot below, we chose screen 2.

Open the Resolution drop-down menu and select a resolution of Windows 10 Recommended or higher for the screen. Press the Apply button.

When the confirmation dialog box appears, click the Keep button . The resolution of the screen you selected will be changed. The resolution of the other screen is not affected. If you do not want to save the changes, press the Revert button .

You can do this more easily on older versions of Windows 10. Cutting down on the Control Panel applet and the appearance of the new Settings app makes simple Windows 10 tasks simple. becomes more complex. That is, the option you need is still there, but you need to take more steps if you want to set different resolutions when in multi-monitor mode.
