Dual Display Delight: Play Two Videos Simultaneously on Your Windows PC
Playing multiple videos side-by-side on a single screen can be incredibly useful for various tasks, from comparing different versions of a clip to monitoring feeds from multiple sources concurrently. While standard media players typically only handle one video instance efficiently, achieving a dual-screen or multi-panel video setup often requires workarounds or specialized software. Manually opening multiple player windows and attempting to synchronize them can be cumbersome and resource-intensive.
Achieving seamless simultaneous playback requires a tool designed specifically for this purpose. A dedicated application can manage multiple video streams within a single interface, optimizing performance and offering integrated controls that apply across all playing videos. This approach simplifies the user experience and makes comparative analysis or multi-source monitoring much more practical and efficient on your Windows 11 or Windows 10 computer.
Introducing GridPlayer¶
To effectively play two or more videos side by side on your Windows PC, consider utilizing a specialized media player. GridPlayer is a notable example of such software. It is a lightweight and open-source video player specifically developed to handle multiple video streams concurrently. Its core design principle is to arrange these videos in a customizable grid layout, making it easy to view several clips at once without needing multiple separate windows.
Unlike more complex multimedia suites that offer extensive editing or conversion capabilities, GridPlayer focuses purely on playback efficiency for multiple sources. This streamlined approach minimizes the software’s footprint and reduces the processing load on your computer’s resources, allowing for smoother playback even when dealing with several high-resolution videos simultaneously. Its simplicity makes it accessible for users who need a quick and reliable way to watch multiple videos in parallel.
Whether your goal is to meticulously compare subtle differences between various video takes, keep an eye on multiple security camera feeds, or simply enjoy watching different perspectives of an event, GridPlayer provides a practical solution. Beyond mere simultaneous playback, it includes features crucial for comparative viewing, such as the ability to synchronize the playback position across all videos. This ensures that when you navigate to a specific timestamp in one video, all other videos in the grid automatically jump to the corresponding point in their timelines, maintaining perfect alignment.
Obtaining and Installing GridPlayer¶
To begin using GridPlayer for your multi-video playback needs, the first step is to download the application files. As GridPlayer is an open-source project, its official distribution channel is typically through repositories like GitHub. Navigating to the project’s dedicated page on GitHub is where you will find the latest releases and installation instructions.
Visit the project’s GitHub page using your web browser. On the main page, scroll down to locate the “Installation” section. GridPlayer typically offers two primary methods for deployment on your system: an installer version and a portable version. The installer provides a traditional software setup experience, integrating the application into your system’s program files and creating start menu shortcuts. Simply download the executable installer file and run it, following the on-screen prompts to complete the installation process.
Alternatively, the portable version offers greater flexibility. Instead of installing the software onto your system, you download a compressed archive (like a ZIP file) containing all the necessary program files. You can then extract these files to any location on your computer, such as a USB drive or a folder on your desktop. To run GridPlayer, simply open the extracted folder and launch the main executable file directly. This method requires no administrative privileges and leaves no traces in the system registry, making it ideal for temporary use or carrying on external media. Choose the version that best suits your preferences and system setup.
Playing Videos Side-by-Side Using GridPlayer¶
Once GridPlayer is installed or the portable version is ready, launching the application will reveal its minimalistic interface, designed around a grid layout. Upon opening, you will see empty cells within the grid, indicating where videos can be placed. The design prioritizes ease of use, with the primary method for adding videos being incredibly intuitive: drag and drop.
Simply select the video files you wish to play from a file explorer window and drag them directly into the GridPlayer window. As soon as the files are dropped, GridPlayer will automatically begin loading and playing them within the available grid cells. The player intelligently arranges the videos within the grid based on its default configuration, attempting to create a balanced layout depending on the number of videos added. This immediate feedback makes testing multiple videos incredibly fast and convenient.
For users who prefer traditional file selection methods or need to add videos from network locations, GridPlayer also provides context menu options. Right-clicking anywhere within the player window brings up a menu. From this menu, select “Add” and then choose “Add Files” to browse your computer’s file system and select videos through a standard file picker dialog.
Beyond local files, GridPlayer also supports playing online video streams. You can add streaming content similarly by dragging the URL of the video stream into the player window. Alternatively, right-click and select “Add > Add URLs”. GridPlayer leverages external tools like streamlink and yt-dlp (you may need to ensure these are accessible or configured correctly for advanced streaming support) to resolve the streaming URLs and integrate the video playback directly into the grid alongside any local files. This capability is particularly useful for monitoring live feeds or comparing online video content.
As videos play, hovering your mouse cursor over any specific video panel will display a seek bar at the bottom of that panel. This seek bar represents the video’s timeline. You can interact with it directly to jump to different points in the video by dragging the slider to the desired position. This allows for quick navigation through individual videos within the grid.
GridPlayer also includes a “Snapshots” feature, which acts like bookmarks within your video playback. You can save up to 10 different snapshots for a video. Each snapshot records the exact time position in the video, allowing you to quickly jump back to those specific moments later. By default, videos added to GridPlayer are set to loop continuously, automatically restarting playback from the beginning once they reach the end, which is useful for repetitive analysis or monitoring.
Advanced Video Control and Synchronization¶
GridPlayer is more than just a simple multi-window player; it offers a suite of controls for individual videos within the grid as well as features that enhance multi-video playback, such as synchronization. Accessing these controls is primarily done through the right-click context menu on the player interface.
Under the Video submenu, you can manipulate the visual aspects of each video panel. Options include the ability to zoom in or out on the video content, allowing for closer inspection of details. You can also crop parts of the video frame, focusing on specific areas of interest. The aspect mode can be adjusted to control how the video fits within its panel, with options like ‘fit’ (maintaining aspect ratio), ‘stretch’ (filling the panel regardless of aspect ratio), or ‘none’ (displaying the video at its native size, potentially overflowing the panel). Furthermore, the Transform options allow you to rotate or flip the video feed at various angles, which can be useful for correcting orientation or viewing mirrored perspectives.
The Audio submenu provides control over the sound for each individual video. You can adjust the volume level independently for every video in the grid. Options are also available to change the audio track if the video file contains multiple audio streams and to quickly mute or unmute specific videos. This is essential when monitoring multiple feeds where audio from only one or a few sources is needed.
Control over the playback itself is managed via the Playback submenu. Here, you can modify the playback speed of a video, allowing you to watch content in slow motion or speed it up for quicker review. This menu also contains options related to the snapshots feature, enabling you to manage your saved timestamps, and modify the loop settings for individual videos, changing the default continuous loop behavior.
The layout of the grid itself can be customized through the Grid submenu. This is particularly useful when playing more than two videos. You can specify how the videos should be arranged within the window, such as arranging them primarily in rows or columns, or using options like ‘fit cells’ to make the grid layout dynamically adjust to the window size and the number of videos. While this article focuses on two videos, the grid options highlight GridPlayer’s scalability for even more sources.
One of GridPlayer’s most powerful features for comparative analysis is found under the Seek Sync submenu. This feature allows you to synchronize the playback progress across multiple videos. You can choose to sync by percentage of the total duration or by absolute timecode. When seek synchronization is enabled, scrubbing or jumping to a specific point in one video will automatically cause all other synced videos in the grid to jump to the exact corresponding point in their timelines. This is invaluable for comparing events that occurred at the same time in different recordings or angles. For instance, if you are comparing two different camera views of the same event, enabling seek sync ensures that when you are viewing the 1-minute mark in one video, the other video also displays content from its 1-minute mark.
To manage your multi-video setups for future use, GridPlayer offers the Save Playlist option. This feature doesn’t just save a list of the video files; it saves the complete configuration of the current session. This includes which videos are loaded, their positions within the grid, individual settings applied (like volume levels, loop settings, aspect ratios, zoom levels, etc.), and even the saved snapshots. Saving a playlist allows you to quickly recreate a specific multi-video layout and its associated settings later by simply importing the saved playlist file, eliminating the need to manually set everything up each time.
Further customization of GridPlayer’s behavior is available through the Settings option, which opens a dedicated configuration window. This window contains various tabs and options to fine-tune how the player operates. A particularly important section is the Advanced settings, where you can configure Video Decoder settings. GridPlayer supports different decoding methods that affect performance:
- Hardware Mode: This mode utilizes your graphics processing unit (GPU) for decoding video streams. Hardware acceleration is generally the most efficient method, providing high performance and reducing the load on your CPU, which is ideal for playing high-resolution videos or multiple videos simultaneously without performance drops.
- Software Mode: In this mode, video decoding is handled solely by your computer’s central processing unit (CPU). While compatible with virtually all systems, it can lead to significant CPU usage, especially with high-definition videos or when playing many streams at once, potentially causing playback stuttering or system slowdowns.
- Hardware SP Mode: This mode attempts hardware decoding but performs the process within the same application process as GridPlayer. While it might offer performance benefits over software mode, it can be unstable or less efficient when playing a large number of videos (the developer notes it’s not recommended for more than 4-6 videos) as it can increase CPU load on the main application thread and potentially cause the application to become unresponsive or freeze.
Understanding and selecting the appropriate video decoder setting based on your system’s hardware capabilities and the number/resolution of videos you are playing can significantly impact the smoothness and stability of the playback. Exploring the other settings within the configuration window allows you to personalize GridPlayer further, tailoring it to your specific needs and improving the overall user experience.

Playing Two Videos on a Laptop Screen¶
Playing two videos simultaneously on a laptop screen involves similar principles as on a desktop, but the limited screen real estate might necessitate optimizing window size and layout. The most straightforward method without specialized software is to open two separate instances of a media player application. Popular players like VLC Media Player or Windows Media Player (or your preferred alternative) can typically run multiple instances concurrently.
Launch the first instance of your media player and open the first video file. Then, launch a second instance of the same or a different media player and open the second video file. You will now have two separate application windows displaying videos. Manually resize each window to occupy approximately half of your laptop screen. Position them side-by-side, ensuring you can see both video feeds clearly. You will need to start playback in each window separately. Keeping them perfectly in sync this way is challenging and requires manual coordination, often pausing and resuming playback in one window to catch up with the other.
Alternatively, as discussed, using a dedicated tool like GridPlayer is a far more efficient and integrated solution for laptop users. GridPlayer manages both videos within a single application window, allowing for easier resizing of the entire container to fit the laptop screen. More importantly, features like seek synchronization built into GridPlayer automatically keep the videos aligned, eliminating the need for manual coordination and providing a much smoother comparative viewing experience on a potentially smaller display.
Playing Multiple Videos Side-by-Side in VLC¶
While GridPlayer is purpose-built for grid playback, VLC Media Player, a widely popular and versatile player, does offer functionality to play multiple videos simultaneously within certain limitations, primarily by allowing multiple instances or using its playlist feature in a specific way.
To play multiple videos by launching separate VLC windows: By default, VLC is often configured to prevent multiple instances from running simultaneously, meaning opening a new video might replace the one currently playing. To change this, open VLC, go to the menu bar and click on Tools, then select Preferences. In the Preferences window, navigate to the Interface section. Look for an option labeled “Allow only one instance” or similar (the exact phrasing might vary slightly depending on your VLC version). Uncheck this box. Click the Save button at the bottom. Now, you can launch multiple VLC windows and open a different video in each, positioning them manually side-by-side on your screen. Again, manual synchronization will be required.
To play multiple videos more synchronously within a single control structure in VLC (though not strictly side-by-side in the same window view like GridPlayer does): Open VLC and go to Media > Open Multiple Files…. In the “Open Media” dialog box, click the Add button to add your first video file. After adding the first file, click the checkbox labeled “Show more options”. This expands the dialog. Within the expanded options, check the box that says “Play another media synchronously (starting at the same time)”. Below this option, a button labeled “Extra media” will appear. Click this button to add your second video file (or subsequent files if you need more). Once all files are added as “Extra media” for synchronous playback, click the Play button. VLC will attempt to play all added videos, often switching between them or layering them in a way that might not be the side-by-side view you desire, but it does manage their playback timing within one control interface. Note: This method doesn’t display them in separate, resizable panels within one window; it’s more for sequential or layered synchronous playback depending on VLC’s rendering capabilities for that specific setup, and achieving a true side-by-side view usually defaults back to running multiple instances. Therefore, running multiple instances with the “Allow only one instance” option unchecked is the more common VLC method for a side-by-side visual comparison, despite the lack of built-in sync controls.
For dedicated, easy-to-manage side-by-side viewing with integrated sync features, GridPlayer remains a more purpose-built and efficient solution compared to stretching the capabilities of general-purpose players like VLC.
Playing multiple videos simultaneously opens up a wealth of possibilities for analysis, comparison, and monitoring. While manual window management offers a basic solution, dedicated software like GridPlayer provides a streamlined and feature-rich experience specifically tailored for this task on Windows PCs.
We hope this detailed guide helps you set up and utilize GridPlayer or understand alternative methods for playing multiple videos side-by-side.
