"There is something wrong with my OBS studio on Windows as it just stopped playing and has a black screen. Can someone tell me how to fix OBS?"

Commonly known as the Open Broadcaster Software, OBS is a cross-platform video recording and streaming service that runs on Linux, macOS, and Windows. While the tool has several applications, it often suffers from a few pitfalls. For instance, getting the OBS screen recorder black screen or experiencing lag in videos are some of the common issues related to it. In this post, I will help you fix these problems related to OBS studio in different ways.

In this article

Part 1: How to fix OBS Lagging

A lot of times, users encounter lagging issues while recording a video with OBS or playing a video that was previously recorded by the tool. Ideally, this can happen due to different software or compatibility issues. If you wish to learn how to make OBS not lag, then you need to implement a handful of solutions.

Common causes for OBS video lagging

Fix 1: Maintain a stable network connection

If you are streaming your videos online, then you need to make sure you have a stable network connection. If the network is not strong, then some frames in your videos might be dropped which can cause them to lag. Ideally, it is recommended to go with an Ethernet connection (wired link) since it is more stable and operates faster.

Fix 2: Check Hardware damage

Just like a network issue, any unwanted hardware damage can also cause OBS videos to lag. You can check the router, the network connection, ports, recording devices, and all the other hardware components to make sure your videos would not lag while playing.

Fix 3: Change the video's bitrate

In most cases, high bitrate is used to enhance the quality of video streaming. Though, it can also increase the dropping of video frames which can cause a lag in your videos. To learn how to stop OBS from lagging, you can consider decreasing the bitrate of the video while recording. Just launch the OBS studio and go to its Settings > Advanced Settings > Streaming. Go to the "Bitrate" tab and manually decrease the bitrate to stop the frames from dropping in between.


Fix 4: Change OBS Settings according to your computer's resolution

This is something that a lot of users ignore while learning how to fix stream lag in OBS. If your computer or the player's resolution is 1080p or 720p, then you need to make some custom settings in OBS. All you have to do is go to OBS settings and visit the Output section from the sidebar. Now, make the following changes as per your computer's supported resolution.

For 720p

Fix 5: Update or Reset the Network Drivers

If your system is running on old or outdated drivers, then you should consider updating them. For instance, if there is an issue with your computer's network adapter, then this would be an ideal fix. To learn how to make OBS not lag on your system, jut go to its Start menu and look for Device Manager. You can also open it from Control Panel > Device Manager as well.


Now, just expand the Network Adapter settings, select the installed drivers, and choose to update it. You can right-click the drivers and select the "Update" option from the context menu to do it. Apart from that, you can disable the driver and enable it later on to reset it.

Fix 6: Check Firewall Settings to allow OBS recording/playback

Lastly, you should check the firewall settings on your computer as a strict firewall or an anti-malware tool can also block certain OBS connections. If you are not sure about the firewall settings on your system, then you can just disable the feature from Control Panel. To further diagnose it, go to Control Panel > System & Security > Firewall/Windows Defender Firewall. Now, click on the option to allow apps or features to pass through the firewall and make sure the OBS studio is allowed to run through the firewall.


Part 2: How to Fix OBS Black Screen

While recording or video playback, users often complain of getting the OBS screen recorder black screen. To learn how to fix OBS black screen, you need to understand its causes and take the needed steps to fix them. Mostly, it is caused by faulty firmware or wrong settings in the application.

Reasons for getting the OBS black screen

Fix 1: Run OBS as an administrator

This is the easiest way to learn how to fix the OBS black screen issue. If you have multiple user profiles on your system, then chances are that you might not have the right to perform certain actions on OBS. To avoid this issue, you can just launch OBS as an administration. Simply select its icon from the desktop or go to the Start menu and look for OBS. Now, right-click the OBS icon and choose to launch it as an administrator. You might be needed to enter the administrator credentials to open OBS on your system now.


Fix 2: Disable Hardware Acceleration

Hardware acceleration is an advanced option in most browsers that put a direct load on the GPU. Though, while doing so, it can tamper with the video streaming experience on the browser and make the screen black. To quickly fix the OBS screen recorder's black screen, you can disable this feature while playing the video on a browser. Just go to its advanced settings and turn off the hardware acceleration option. You can find it listed under the advanced settings option in both Chrome and Firefox.


Fix 3: Turn off the Game Mode feature on Windows 10

Windows 10 has an inbuilt Game Mode feature to improve the overall gaming experience of the user. Though, if the Game Mode is enabled, then you might find it hard to record your gameplay with third-party tools like OBS. Therefore, to quickly learn how to fix OBS black screen, consider turning the Game Mode option off. Just go to your Start Menu and click on the gear icon to open Windows 10 Settings. Browse to the Gaming settings and disable the Game Mode feature from here.


Fix 4: Run OBS in Compatibility Mode

There could be any compatibility issue for getting the OBS screen recorder black screen as well. For instance, your operating system might just be recently updated or there could be a driver-related issue. To learn how to fix OBS issues of these kinds, you can just open it in compatibility mode. To do this, right-click its icon from the desktop (or the location where it is installed) and go to its Properties > Compatibility. From here, you can turn on the option to run the program in compatibility mode.


Fix 5: Switch the GPU load

If you have two graphic cards installed on your system, then you can just switch the OBS load to fix the black screen issue on it. For instance, if you have an NVIDIA card installed on your computer, then launch the NVIDIA Control Panel and go to the Manage 3D Settings option. Under the Program Settings, go to the "Select the program to customize" field and browse the OBS application from here. Later, you can select the kind of performance (optimized or high) that you wish to implement with the application.
