If OBS just records a small window instead of the full screen, you may choose the incorrect capturing source. Just follow the steps below to fix it.
Step 1. Click on the β+" button under the βSourceβ tab. Select βDisplay Captureβ from the source options.
Step 2. It will open a small βCreate/Select Sourceβ window. You can name the source as βFull Screenβ or leave it as default. Press βOKβ to go to the next step.
Step 3. In the βProperties for βDisplay Captureββ window, you can uncheck the βCapture Cursorβ window if you donβt want to capture the cursor. Click βOKβ to add the βDisplay Captureβ source.
Step 4. The capturing window will show the full screen and you can press βStart Recordingβ to make OBS record full screen now.
The other reason for the OBS full screen not working may be the incorrect base and output resolutions you set. When recording a game, if the Base(Canvas) Resolution doesnβt match your game resolution, it will result in a small screen recording. And you need to change the base resolution with the following steps to fix the issue.
Step 1. Click the βSettingsβ button below the βControlβ panel or press βFileβ > βSettingsβ to bring up the βSettingsβ window.
Step 2. Select the βVideoβ tab and then change the βBase (Canvas) Resolutionβ to the highest to match your screen resolution. The βOutput (Scaled) Resolutionβ also needs to be set to match the game resolution.
Step 3. Click on βApplyβ and then press βOKβ to save the changes.
Step 4. Then you can add the capturing source and start recording in full screen.
If you have two graphics devices and one is NVIDIA, that may be because OBS and the game you need to capture run on different graphics cards. As they are on separate connectors, the image of the game cannot be obtained because it is not available on the device OBS is on. So follow the steps below to switch OBSβs GPU.
Step 1. Right-click on the desktop screen and select βShow more optionsβ.
Step 2. Choose βNVIDIA Control Panelβ and open it.
Step 3. Open βManage 3D settingsβ on the left side panel and select βProgram Settingsβ on the right board. Press βAddβ.
Step 4. Select OBS Studio under the βSelect a program to customizeβ section.
Step 5: Pick βSuperior NVIDIA processorβ under the βSelect the preferred graphics processor for this programβ drop-down menu. Press βApplyβ.
Step 6. Close the NVIDIA Control Panel and restart OBS to check whether the issue is fixed or not.
If other recording programs are running on your PC and have taken precedence in capturing the window or screen, OBS may also fail to record the full screen. To fix that, you need to enable the Compatibility mode for OBS Studio.
To run OBS Studio in compatibility mode, you need:
Step 1. Right-click on the OBS Studio shortcut on your desktop or in the Start menu and select βPropertiesβ.
Step 2. Switch to the βCompatibilityβ tab at the top of the βOBS Studio Propertiesβ window.
Step 3. Under the βCompatibility modeβ section, check the box beside βRun this program in compatibility mode for:β.
Step 4. Click on βApplyβ and then press βOKβ.
Step 5. Restart OBS Studio and add the capturing source to check if the OBS not recording full screen issue is fixed or not.
Game Bar is the Windows default game recorder. If it is activated, then it may restrict you from recording the game in full screen with OBS. So you can turn off the Game Bar recording to make your OBS full-screen recording successfully.
Step 1. Click the start icon on your Windows PC and choose "Settings".
Step 2. Select "Gaming" and then turn off the Xbox Game Bar for recording...
Step 3. Right-click on OBS and choose "Run as Administrator".
This should allow you to record game in full screen with OBS.
If the solutions listed above cannot fix the OBS fullscreen not working issue, you can locate the folder where you installed OBS and uninstall it as well as the leftover files of OBS Studio. Then install it and launch it to see if it works now.
