How to add or change screen resolution on a laptop: instructions for Windows, macOS and Linux

Screen resolution is a key parameter that affects image clarity, ease of use, and even the health of your eyes. If the picture on your laptop is blurry, too large, or, conversely, small, it means that the current settings are not optimal for your display. But how right add new resolution, if it is not in the standard list? Or return to factory settings after unsuccessful experiments?

In this article you will find step by step instructions for all popular operating systems - from Windows 10/11 to macOS Ventura and distributions Linux. We'll also look at why some permissions may be missing from the menu, how to force them to be added through drivers or third-party utilities, and what to do if the screen turns black after making changes. A separate block is dedicated to laptops with hybrid graphics (NVIDIA Optimus/AMD Switchable), where settings may conflict between the integrated and discrete graphics cards.

Why is it important to choose the right resolution?

Screen resolution determines the number of horizontal and vertical pixels. For example, 1920×1080 (Full HD) means 1920 pixels in width and 1080 in height. The higher the resolution, the clearer the picture, but the smaller the interface elements become. The optimal value depends on the display diagonal and its physical resolution (for example, 4K-a 15.6-inch screen will require scaling, otherwise the text will be unreadable).

Incorrect settings lead to:

• 🔍 Blurry fonts — when the system tries to stretch the image to a non-native resolution.
• 🖥️ Trimming desktop — if you select a resolution that is not supported by the monitor.
• 👁️ Tired eyes — text is too small or flickers at an incorrect refresh rate.
• 🎮 Problems in games — some applications block launch if the screen resolution does not meet the minimum requirements.

For example, laptops Lenovo ThinkPad or Dell XPS with screens 3840×2400 often come with 200-250% scaling, otherwise icons and text will be too small. And on budget models (Acer Aspire, HP Pavilion) with permission 1366×768 scaling is usually not required.

⚠️ Attention: If you connect your laptop to an external monitor, the resolution must be supported both devices. For example, an old projector with maximum resolution 1024×768 will not display the image in 1920×1080 without loss of quality.

How to change resolution in Windows 10 and 11

In the latest versions of Windows, the process is almost identical, but there are some nuances with scaling and support for high resolutions (4K/5K). Here are the general instructions:

1. Click Win + Ito open Options.
2. Go to section System → Display.
3. In the block Scale and layout find the drop down list Screen resolution.
4. Select a recommended value (labeled "(recommended)") or another from the list.

If you don't have the required permission:

• 🔧 Update your video card driver via Device Manager (section Video adapters).
• 🖱️ Use the graphics control panel (NVIDIA Control Panel or AMD Radeon Software), where additional modes are often available.
• 💻 For Intel video cards (Intel UHD Graphics) download the utility Intel Graphics Command Center.

Update your video card driver

Create a system restore point

Disconnect external monitors (if connected)

Remember the current permission in case of rollback-->

On laptops with hybrid graphics (for example, ASUS ROG Zephyrus with NVIDIA RTX + Intel Iris Xe) You may need to manually select which graphics card controls the display. To do this:

1. Open NVIDIA Control Panel (right click on the desktop).
2. Go to Manage 3D settings → Program settings.
3. Select Integrated Graphics for economy mode or High performance NVIDIA processor for maximum resolution.

⚠️ Attention: On some laptops (MSI Modern, HP Spectre) when forced to add a non-standard resolution via Custom Resolution Utility (CRU) The update rate may be lost. Before experimenting, check whether your screen supports the selected frequency (for example, 144 Hz on 1920×1080).

Adding a custom resolution in Windows

If the standard list does not contain the required permission (for example, 2560×1440 for QHD-screen), it can be added manually. For this you will need:

• 🛠️Utility Custom Resolution Utility (CRU).
• 📊 The exact parameters of your display (can be found in the documentation or via AIDA64).

Instructions:

1. Download and run CRU (does not require installation).
2. In the program window, select your monitor from the list Detailed resolutions.
3. Click Add and enter the desired resolution (for example, 3440×1440 for ultra-wide screen).
4. Specify the update frequency (usually 60 Hz, but for gaming monitors it may be 120 Hz or 144 Hz).
5. Save changes and reboot.

After the reboot, the new resolution will appear in the standard Windows settings. If the screen turns black:

• Wait 15 seconds - the system should automatically rollback the changes.
• If not, restart your laptop in safe mode (F8 when loading) and remove the custom resolution via CRU.

Setting resolution on macOS (Ventura, Monterey, Big Sur)

On a MacBook the process is simpler, but there are nuances with Retina displays, where the physical and “effective” resolution differ. To change settings:

1. Open System Settings → Monitors.
2. Click Scaling (in older versions of macOS - Resolution).
3. Select one of the proposed options. Option Default corresponds to the native resolution of the Retina screen.

If the required mode is not available:

• 🔄Hold Option (Alt) and click on Scaling - additional options will appear, including Low Resolution (useful for older applications).
• 🖥️ For external monitors, use the utility SwitchResX (paid, but supports custom permissions).

On MacBooks with M1/M2 chips, when connected to a 4K monitor via HDMI, the maximum resolution may be limited to 30 Hz instead of 60 Hz. For 60 Hz you need a DisplayPort or USB-C → DisplayPort adapter.

If the image is blurry after the changes:

• Return to Default and check the scaling settings in System Preferences → Accessibility → Display.
• For external monitors, calibrate the color profile to System Preferences → Monitors → Color.

Changing resolution in Linux (Ubuntu, Fedora, Mint)

In Linux distributions, the settings depend on the graphical shell (GNOME, KDE Plasma, XFCE) and video card drivers. Let's consider universal methods:

Method 1: Via GUI

B Ubuntu with GNOME:

1. Open Settings → Devices → Displays.
2. Select your monitor and click on the current resolution.
3. If the option you need is not available, install proprietary drivers for NVIDIA or AMD:

sudo ubuntu-drivers autoinstall
sudo reboot

Method 2: Via terminal (xrandr)

Utility xrandr allows you to control resolution from the command line:

1. Check out the available modes:

xrandr -q

2. Add a new permission (for example, 1920x1080):

cvvt 1920 1080 60
xrandr --newmode "1920x1080_60.00" 173.00 1920 2048 2248 2576 1080 1083 1088 1120 -hsync +vsync
xrandr --addmode HDMI-1 "1920x1080_60.00"
xrandr --output HDMI-1 --mode "1920x1080_60.00"

Replace HDMI-1 to your interface (you can find out via xrandr -q).

If the screen goes dark after use:

• Wait 10-15 seconds - the system should roll back the changes.
• If not, switch to the console (Ctrl + Alt + F2), log in as your user and delete the custom mode:

xrandr --delmode HDMI-1 "1920x1080_60.00"

⚠️ Attention: On some laptops with Wayland (instead of X11) team xrandr may not work. In this case, use the display settings in the graphical shell or switch to Xorg when logging in.

Solving permission problems

If problems arise after the changes, use these instructions:

1. The screen turned black

• 🔄 Wait 15-20 seconds - Windows/macOS/Linux should automatically return to the previous settings.
• 🖥️ If the laptop does not respond, connect an external monitor and cancel the changes.
• 🔌 On Windows, hold down Win + Ctrl + Shift + B - this will restart the video card driver.

2. Permission resets after reboot

The reason is a driver conflict or lack of support for custom mode. Solutions:

• 🔧 Update the video card driver manually (download from the manufacturer’s website, not through Windows Update).
• 📝 For Windows: export settings CRU to file reset-all.exe and add it to startup.
• 🐧 For Linux: add the command xrandr to autorun (file ~/.xprofile).

3. Blurry text or icons

The problem is typical for high resolutions (4K) on small screens. Correction:

• 🔍 On Windows: adjust the zoom to Settings → System → Display → Zoom (optimally 125–200%).
• 🍎 On macOS: enable Magnification in display settings.
• 🐧 On Linux (GNOME): use gsettings set org.gnome.desktop.interface text-scaling-factor 1.25.

Optimizing resolution for games and design

For gamers and designers, not only resolution is important, but also refresh rate, color reproduction and HDR support. Here's what to consider:

For games

• 🎮 Choose native resolution monitor (for example, 1920×1080 for Full HD) to avoid blur.
• 🔄 If FPS is low, lower resolution to 1600×900 or 1280×720, but turn on antialiasing in the game settings.
• 🖥️ On laptops with NVIDIA Optimus run games through a discrete graphics card (right click → Run with GPU → NVIDIA High Performance CPU).

For design and graphics work

• 🎨 Use scaling 100% (without magnification) to see the actual pixel size.
• 🖼️ For Adobe Photoshop or Figma adjust the color profile in Settings → System → Display → Advanced screen options (Windows) or System Preferences → Monitors → Color (macOS).
• 🔍 On 4K screens, turn on DPI scaling in the application properties (right-click on the executable file → Compatibility → Change High DPI).

For color professionals, it is important to calibrate your monitor. Windows has a built-in utility for this:

1. Open Control Panel → Hardware and Sound → Screen Calibration.
2. Follow the instructions to adjust gamma, brightness and contrast.
