How to identify screens in a digital art setup

If you work with a drawing tablet, laptop screen, and external monitor, it can be easy to lose track of which display is showing your artwork. That matters when you choose where to put your canvas, compare references, or check whether a color looks different on one screen.

The Screens tool lists the connected screens it can detect, along with their resolution and scale. Its color test helps you match an entry in the list to the physical display in front of you.

Identify each screen

1. Open Screens on the computer connected to your displays. Check that the screens you expect to use appear in the list.
2. Note the resolution and scale shown for each screen. Compare these details with the display arrangement in your operating system, especially if two monitors have similar sizes.
3. Use the color test for one screen entry. Look at each physical display and note which one shows the test. Repeat for the other entries so you can match each one to a location, such as the built-in laptop screen or the monitor on the left.
4. Open your art program and check where its window and canvas appear. If the canvas is on the wrong display, move the window or change the screen arrangement in your operating system.

For a setup with more than one monitor, write down a simple map, such as “screen 1, laptop, 1920 by 1200” and “screen 2, left monitor, 2560 by 1440.” The numbers are only useful if you connect them to the actual screens, rather than relying on position or numbering alone.

What the results mean

You can match each screen to its entry

The computer and browser can distinguish the displays well enough for you to identify them. Use the map to place the art program, reference images, and other windows where you expect them. If you want more detail on display scale, see per-screen scaling for a digital art setup.

The displays show the same image

Your desktop may be mirroring the displays. In mirror mode, both screens show the same desktop, so a visual test may not help you tell their physical positions apart. Switch to an extended desktop if you want a separate canvas or reference on each monitor.

The colors look different between displays

This confirms that you are looking at different screens, but it does not prove that either one is accurate. Differences can come from brightness, color settings, screen technology, or the color profile used by the operating system. A browser color pattern is a visual check, not a calibration measurement.

A screen is missing

The browser is not showing that display as an available screen. Check whether the operating system detects it. If it does not, the issue is more likely to involve the monitor, cable, adapter, dock, or display settings than the art program.

The resolution or scale looks unexpected

Check which screen is selected in your operating system before changing anything. Resolution affects the display’s pixel dimensions, while scale changes the size of interface elements. On high-density displays, the numbers reported for resolution and scale may not match the physical pixel count in a simple one-to-one way.

Fix the screen layout

1. Use an extended desktop. In Windows 11, open Settings › System › Display, select the display arrangement, and choose Extend these displays under the multiple display options. On macOS, open System Settings › Displays and check the arrangement and display-use options. The exact controls can vary by macOS version.
2. Identify the displays in system settings. In Windows 11, open Settings › System › Display and select Identify. Match the number shown on each physical screen to the layout diagram. On macOS, use the arrangement view in System Settings › Displays to match the displays by their position and move them into the layout you use at your desk.
3. Check resolution and scale for each screen. In Windows 11, select a display under Settings › System › Display, then review Display resolution and Scale. On macOS, select a display under System Settings › Displays and review its available resolution or scaling options. Use the recommended or default setting first, then retest.
4. Turn off color-changing display features while comparing. Windows 11 has Night light under Settings › System › Display. On macOS, check System Settings › Displays for Night Shift and, if available, True Tone. These features can change the appearance of colors. Turn them back on afterward if you normally use them.
5. Reconnect a missing monitor. Confirm that the monitor is powered on and set to the input used by its cable. Disconnect and reconnect the cable at both ends, then try another port or adapter if available. Restart the computer only after checking the simpler connections.

When it's a connection or hardware problem

If the operating system and the Screens tool both fail to show a monitor, test the display with a different cable or port, and connect it directly to the computer if you can. A dock or adapter can be the cause even when the monitor works by itself. If the display still does not appear on another computer, or its image cuts out when the cable is touched, contact the manufacturer or a repair shop. Avoid changing color settings until the connection is stable.

Screen identification is not color calibration

Identifying a screen tells you which display you are working with, not whether it can reproduce a color accurately. Two monitors can show the same test pattern differently because of their panels, brightness settings, viewing angle, or color profiles. For digital art, use the screen identification check to confirm where your canvas appears, then use a suitable calibration process if you need dependable color matching for print or delivery.
