Record a fullscreen tutorial on an ultrawide screen

Your tutorial looks fine while you record, but the video is too wide, the controls are hard to read, or the app turns black when you switch to fullscreen. An ultrawide screen gives you plenty of room to work, but viewers may watch on a much narrower display.

Use the Screen Recorder to capture your screen, a window, or a browser tab. Before you start, decide what viewers need to see and set up the desktop so the useful part of the screen is easy to follow.

Record the tutorial

Open the Screen Recorder on your computer. It does not work on phones. Close private tabs, hide notifications, and open the app or page you plan to demonstrate.
Choose a capture area in the browser's screen-sharing picker. For a fullscreen application, share the entire screen if the picker does not offer the app window or if window capture shows a blank image. For a browser lesson, sharing just the tab can keep unrelated desktop content out of the video.
Choose whether to include sound, your microphone, or your camera if those options are needed. Check the microphone before recording, and make sure your computer's output is set to the speakers or headphones you want the tutorial sound to come from.
Start the recording, then switch to the tutorial and enter fullscreen. Pause briefly before the first action so viewers can see the starting screen. Move the pointer deliberately and keep it near the area you are explaining.
When the demonstration is finished, return to the recorder and use its stop control. Follow the recorder's on-screen steps to save the video, then open the saved file and check the beginning, middle, and end before sharing it.

If the browser asks for permission to share your screen, allow it and choose the intended screen, window, or tab in the picker. A screen recording can show everything visible on that display, including pop-up notifications and personal information.

Choose the right capture area

Capture the entire ultrawide screen

This is the most reliable choice for a fullscreen app or a demonstration that moves between programs. The recording keeps the monitor's wide shape, so the app will be visible edge to edge. The tradeoff is that viewers on a phone or a standard 16:9 display may see unused space above and below the video, or need to zoom in to read small controls.

Capture one application window

Window capture can exclude the desktop and make a focused tutorial feel cleaner. It may not follow an app correctly when the app changes display modes, minimizes, or opens a separate window. If the recording turns black or stops showing the app after fullscreen starts, stop and try sharing the entire screen instead.

Capture a browser tab

Tab capture is useful when the lesson stays in one web page. It avoids recording other open windows, and some browsers offer a separate option to include tab audio. If the tutorial leaves the tab or uses another app, choose a screen or window capture instead.

Make the video easy to follow

Keep the key area near the center. Put the important app controls and content where viewers can see them without scanning the full width. Avoid placing essential instructions at the far edges of the ultrawide frame.
Make small interface text larger. Increase the app's zoom or text size before recording if labels are difficult to read. On Windows 11, check Settings › System › Display › Scale. On macOS, check System Settings › Displays for a display scaling option. Test the view before recording, because changing scale can move controls or alter the layout.
Use a steady pointer pace. Move the cursor to a control, pause, then click. Fast movement across a wide screen is difficult to track, especially in a compressed video.
Keep notifications out of the take. Turn on your computer's do-not-disturb or focus setting, and close unrelated windows. This also helps avoid accidentally recording messages or account details.
Do a short test recording. Record a few seconds with the app in fullscreen, then play it back. Check that the image is not black, the pointer is visible, and any voice or app sound is present at a comfortable level.

Fix common fullscreen recording problems

Share the screen instead of the window. Some apps change their display surface when they enter fullscreen, which can leave a window capture blank. Stop the recording and select the entire display in the browser's sharing picker.
Check the selected display. If you have more than one monitor, make sure the picker is sharing the ultrawide screen that contains the tutorial. A recording of the other display can look empty even though the recorder is working.
Allow screen recording access. On macOS, open System Settings › Privacy & Security and look for the screen recording permission for your browser. Enable access if it is off, then restart the browser if macOS asks you to. On Windows 11, respond to the browser's screen-sharing prompt and choose a capture source in its picker.
Check sound separately from video. A screen capture can look correct while the audio source is wrong or missing. Confirm the recorder's sound and microphone options before starting, and make a short test to check playback.
Close other screen-capture software. Another recorder or meeting app can interfere with screen or microphone access. Quit those apps, reload the recorder, and grant permission again if prompted.
Use a desktop browser. Screen Recorder does not work on phones. If capture is unavailable on a computer, try an up-to-date browser and check whether your organization manages or blocks screen-sharing permissions.

Why an ultrawide video may not fill the viewer's screen

An ultrawide monitor records a wider image than a typical phone or laptop display. The recorder captures the selected screen's shape; it does not automatically crop the sides into a 16:9 frame. Cropping later can cut off controls, while shrinking the full image can make text harder to read. If most viewers use standard screens, consider keeping the demonstration within a centered area and enlarging the app content before recording.

The Screen Recorder runs in your browser. Recordings stay on your device, and nothing you record is uploaded.
