Get the best display on your monitor

[This information is preliminary and subject to change.]

Windows chooses the best display settings for your PC based on your monitor. If you want to adjust your display settings, or if they were changed and you want to restore default settings, here are a few things you can try.

Afficher tout

Set your monitor to its native resolution

It's a good idea to set your monitor to the resolution it was designed to display (called the native resolution). To see your monitor's native resolution, check the display settings in PC settings.

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. Tap or click the resolution slider and drag it until you find the resolution marked (Recommended). This is your monitor's native resolution—usually the highest resolution your monitor can support.

  4. Tap or click Apply.

Resolution options in PC settingsThe slider in PC settings shows the recommended resolution for your monitor.

Monitors can support resolutions that are lower than their native resolutions, but text won't look as sharp and the display might be small, centered on the screen, edged with black, or stretched.

Recommended screen resolutions

Monitor sizeRecommended resolution (in pixels)

19-inch standard ratio monitor

1280 × 1024

20-inch standard ratio monitor

1600 × 1200

20- and 22-inch widescreen monitors

1680 × 1050

24-inch widescreen monitor

1920 × 1200

Laptop screen sizeRecommended resolution (in pixels)

13- to 15-inch standard ratio laptop screen

1400 × 1050

13- to 15-inch widescreen laptop screen

1280 × 800

17-inch widescreen laptop screen

1680 × 1050

Tablet screen

1360 × 768

Set brightness and contrast

You can set the brightness and contrast for most monitors using buttons or other controls on the monitor, not in Windows. If you aren't sure how to adjust the brightness and contrast on your monitor, check the manual or the manufacturer's website.

To adjust brightness automatically

Some PCs adjust screen brightness automatically based on how much light there is in the room where you're using the PC. To see if your PC has this setting, follow these steps.

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. Make sure the Adjust my screen brightness automatically slider is turned on.

    (If you don't want the screen brightness to change automatically, tap or click the Adjust my screen brightness automatically slider to turn it off.)

    Note

    Note

    This setting might not be available on some PCs.

  4. Tap or click Apply.

To adjust brightness for a laptop screen

For most laptop screens, you can adjust brightness in Power Options in Windows.

  1. Tap or click to open Power Options in Control Panel.

  2. Under the plan that you want to change, tap or click Change plan settings.

  3. On the Change settings for the plan page, choose the brightness settings that you want to use when your PC is running on battery (if applicable) and when it's plugged in.

Note

Note

On a laptop, you can also try adjusting the brightness by holding down the Fn key, and then pressing the corresponding function key to increase (The Increase brightness button) or decrease (The Decrease brightness button) the brightness of the display.

Adjust settings for multiple monitors

If you're using more than one monitor, you can identify the monitors that are plugged in, detect another monitor, change the screen orientation, choose what's displayed on each monitor, and choose which one is the main display.

Identify your monitors

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. Tap or click Identify.

Detect another monitor

If another monitor is plugged into your PC but Windows didn't detect it automatically, you can detect it manually in PC settings.

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. Tap or click Detect.

Change the screen orientation

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. In the Orientation list, choose the screen orientation you want to use.

Choose what's displayed on each monitor

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. In the Multiple monitors list, choose one of the following:

    • Extend. You'll see one continuous display that stretches across all of your monitors.

    • Duplicate. You'll see the same display on each of your monitors.

    • Show only on 1. You'll only see the display on your first monitor.

    • Show only on 2. You'll only see the display on your second monitor.

Choose the main display

  1. Swipe in from the right edge of the screen, tap Settings, and then tap Change PC settings.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, click Settings, and then click Change PC settings.)

  2. Tap or click PC & devices, then tap or click Display.

  3. In the preview image, tap or click the monitor you want to use as your main display to select it.

  4. Select the Make this my main display check box.

Tips

Tips

  • You can use the four corners of any monitor to open the Start screen, charms, and your recent apps.

  • You can have the Start screen and apps from the Windows Store on only one monitor at a time. When you open the Start screen, charms, or your recent apps on a different monitor, apps from the Windows Store also move to that monitor.

Make text and other items on the desktop larger

If text and other items (like icons) on the desktop are too small, you can make them larger without changing the screen resolution.

  1. Tap or click to open Display in Control Panel.

  2. Drag the slider until the items in the preview image are the size you want them to be.

  3. Tap or click Apply.

    You'll see the change the next time you sign in to Windows.

Note

Note

This might not be available for some displays.

You can also change the text size for specific items in Windows, like window title bars or tooltips, without changing the size of anything else on the desktop.

  1. Tap or click to open Display in Control Panel.

  2. Under Change only the text size, choose the item you'd like to change and pick a text size. If you want the text to be bold, select the Bold check box.

  3. Tap or click Apply.

    You'll see the change the next time you sign in to Windows.

Help make text easier to read for long periods of time

The ClearType technology in Windows helps make the text on your screen as clear and smooth as possible and can help make text easier to read over long periods of time. ClearType is turned on by default, but it's a good idea to make sure it wasn't turned off for some reason, especially if the text on your screen looks fuzzy.

  1. Swipe in from the right edge of the screen, and then tap Search.
    (If you're using a mouse, point to the lower-right corner of the screen, move the mouse pointer up, and then click Search.)

  2. In the search box, enter ClearType, then tap or click Adjust ClearType text.

  3. Make sure the Turn on ClearType check box is selected, and then tap or click Next. On each page, tap or click the text sample that looks best to you.

  4. On the last page of the tuner, tap or click Finish to save your settings. Administrator permission required You might be asked for an admin password or to confirm your choice.

Calibrate your display

Display Color Calibration helps you improve your display color and make sure that colors are represented accurately on your monitor.

To use Display Color Calibration

  1. Tap or click to open Display Color Calibration. Administrator permission required You might be asked for an admin password or to confirm your choice.

  2. On the Welcome to Display Color Calibration page, tap or click Next to continue.

  3. On the Set basic color settings page, press the Menu button on your monitor (it's likely to be on the front). An on-screen menu will appear. Use the monitor buttons to navigate through the on-screen menu to verify (or adjust) one or more of the following settings:

    • Locate the color menu for choosing the color mode, and then set your display to sRGB.

      If you see the option to select a color temperature (also called a white point) rather than a color mode, set the color temperature to D65 (or 6500).

    • Find the menu to set gamma. Set gamma to 2.2, which is the default setting.

    • If you can’t find any of these settings, look for a setting in the on-screen menu where you can reset your display to the factory default color settings, and then choose that option.

    • If the basic color settings aren't shown in your monitor's on-screen menu, just tap or click Next to continue.

    Note

    Note

    The menu and monitor buttons vary by model and manufacturer. To get help using the buttons for your monitor, check the manual or the manufacturer's website.

  4. On each page in Display Color Calibration, follow the on–screen instructions and tap or click Next when you're done. The following list has more info about each of the settings.

    • Gamma. This helps make sure that details like shades of color and shadows look right on your screen.

    • Brightness. This determines how dark colors and shadows appear on your screen. You can adjust brightness so that dark colors appear accurately, and so that you can still see shadows, outlines, and other details in the darker images. If brightness is set too high, black colors appear light and gray. To adjust brightness settings, look for either a Brightness button or a Menu button on your monitor. If you're using a laptop, try adjusting the brightness by holding down the Fn key, and then pressing the corresponding function key to increase (The Increase brightness button) or decrease (The Decrease brightness button) the brightness of the display.
    • Contrast. This determines how white and light colors appear on your screen. You can adjust contrast so that highlights in images appear accurately. To change contrast settings, look for either a Contrast button or a Menu button on your monitor. (There aren't usually controls for adjusting the contrast on a laptop display.)

    • Color balance. This improves how shades of gray appear on your screen.

  5. On the You've successfully created a new calibration page, tap or click Previous calibration to see your old display calibration. Then tap or click Current calibration to see your new display calibration.

  6. Do one of the following, depending on which calibration you want to use:

    • To use the new calibration, tap or click Finish.

    • To use the previous calibration, tap or click Cancel.

  7. Select whether to use the ClearType Text Tuner to help make sure that text appears clearly with your new calibration.

Note

Note

If you have a display calibration device and software, it's a good idea to use them instead of Display Color Calibration because they'll give you better calibration results.

Choose the best display settings for a CRT monitor

If you have an older cathode ray tube (CRT) monitor, it's important to change the screen resolution to the highest resolution available that provides 32-bit color and at least a 72-Hertz refresh rate to prevent the screen from flickering.

Recommended resolutions for CRT monitors

Monitor sizeRecommended resolution (in pixels)

15-inch CRT monitor

1024 × 768

17- to 19-inch CRT monitor

1280 × 1024

20-inch and larger CRT monitor

1600 × 1200

Note

Note

CRT monitors generally don't come in widescreen sizes. Almost all have standard 4:3 screen and resolution ratios.

Je n'ai pas ajouté la liste des raccourcis que tlm connait par cœur qui permet d'accéder rapidement à certaines fonctions.

Exemples dans notre cas de luminosité:

1 La Barre des charmes s'obtient par le raccourci (Win + I) qui possède l'icône de luminosité.

2 Un clic droit sur le logo Windows (coin bas gauche) et on retrouve Options d'alimentation et notre curseur de luminosité.

Par curiosité j'ai jeté un coup d'œil sur d'autres PC.

1 un netbook Compaq (HP) ne permet pas d'ajuster la luminosité,

2 un Lenovo refuse de bouger le curseur de luminosité,

3 le HP du début est toujours docile.

Etonnant non?


A mon avis tu dois contacter Microsoft et le fabricant/vendeur de ton écran pour soumettre le problème.
