How to Switch Which Monitor Is Shown on Stream
You’ve got your fancy microphone, your decent webcam, and you’re ready to go live. Then you realize… you’ve got two monitors and your chat is probably seeing your embarrassing browser history. Ugh. Figuring out how to switch which monitor is shown on stream can feel like you’re trying to defuse a bomb while juggling flaming chainsaws. Honestly, most of the online advice is either too technical or glosses over the actual fiddly bits. I’ve been there, staring at my OBS settings, sweat dripping onto my keyboard, wondering why my game capture is showing my desktop wallpaper instead of the actual game.
It’s not always as simple as just clicking a button, and for a while, I was convinced my streaming software hated me. I wasted a good chunk of an afternoon, and nearly a whole stream, trying to get the right display captured. The sheer frustration of it all made me want to just give up and go back to playing video games without anyone watching. But after a lot of trial and error, and probably a few muttered curses directed at my monitor arrangement, I’ve got this down. It’s less about magic and more about understanding a few key concepts.
Getting this wrong means your audience sees a blurry mess, or worse, something you absolutely do not want them to see. So, let’s cut through the jargon and get this sorted, because frankly, nobody needs that kind of stress during a live broadcast.
Understanding Your Display Setup
Before we even touch streaming software, you need to know what’s going on with your actual computer. Most streamers these days run at least two monitors. One is usually for the game or the main application you’re showing off. The second? That’s your command center: chat, OBS/streaming software, music player, maybe even a browser with notes for your stream. When you’re trying to figure out how to switch which monitor is shown on stream, the first step is identifying which physical monitor is which in your computer’s eyes.
When I first started, I just assumed my left monitor was ‘Monitor 1’ and my right was ‘Monitor 2’. Big mistake. My computer saw them in a completely different order. This caused a cascade of confusion when I tried to select the right one in my streaming software. It looked like this: I’d tell OBS, ‘Show me Monitor 2,’ and it would dutifully display my game, which was on my *actual* Monitor 1. My chat was left staring at my meticulously organized desktop on what I *thought* was Monitor 2. The sheer indignity of it all. To check, go to your Windows Display Settings (right-click on your desktop and select ‘Display settings’). You’ll see numbered boxes representing your monitors. Drag them around on screen to match their physical location. Crucially, pay attention to which number corresponds to which physical screen.
This simple step, costing you maybe 30 seconds of poking around your settings, will save you hours of headache. Seriously, I spent at least three hours banging my head against the wall before I even looked at these settings. It felt like trying to cook a gourmet meal with the oven set to ‘broil’ when you needed ‘bake’ – the appliance is fine, but the settings are all wrong for the task.

The Obs/streaming Software Dance
Okay, now you know which monitor is which. Time to get your streaming software to cooperate. For most people, this means OBS Studio, Streamlabs, or XSplit. The principle is the same across all of them: you’re adding a ‘Source’ to your scene. When you add a ‘Display Capture’ source, you’ll be prompted to select which display you want to capture. This is where you select the correct monitor number you identified earlier.
Let’s say you want to stream your gaming setup, where your game runs on your primary, high-refresh-rate monitor (let’s call it Monitor 1) and your chat and OBS are on your secondary monitor (Monitor 2). You’d add a ‘Display Capture’ source in OBS and select ‘Display 1’. Easy, right? Well, usually. Sometimes, the software gets confused, or your graphics drivers are being… let’s just say ‘quirky’.
One thing I’ve found, and this goes against some advice out there, is that sometimes forcing a specific refresh rate on your monitor can actually cause more problems than it solves when it comes to screen capture. My buddy Steve, bless his heart, swore by setting everything to 60Hz. He ended up with stuttering streams because his high-end GPU was struggling to downscale consistently. I disagree with that approach; I find it’s better to let the system handle refresh rates unless you’re experiencing specific, undeniable issues. Let the hardware do its thing first.
The physical setup of your monitors also plays a role. If your monitors are set up side-by-side in Windows, and you select ‘Display 1’, OBS will capture whatever is *primarily* on that display. If you drag a window across the boundary between monitors, OBS might get confused, or it might only capture the portion that’s within the selected display’s borders. It’s like drawing a line in the sand; anything on the wrong side of that line is fair game for being ignored by the capture source.
When Your Game Takes Center Stage
So, you’ve got your ‘Display Capture’ set up for Monitor 1, and your game is running beautifully. But wait, you need to quickly check a chat message, or maybe your cat just walked across your keyboard, and you accidentally hit Windows+D, minimizing your game. Suddenly, your stream is showing your desktop wallpaper, not your epic boss battle. This is where ‘Game Capture’ sources come in, and why they’re often preferred for actual games.

Instead of capturing the entire monitor, ‘Game Capture’ specifically targets a running application. You add a ‘Game Capture’ source, select the game from a dropdown, and OBS will try to hook into that specific process. This is generally more performant and reliable because it doesn’t rely on your OS drawing the entire screen. It’s like having a personal assistant who only brings you the document you asked for, rather than a full filing cabinet.
I remember one stream where my game capture kept dropping frames like a bad habit. I spent nearly 45 minutes fiddling with settings, convinced my internet was the culprit. Turns out, a Windows update had subtly changed how it handled full-screen applications, and my ‘Game Capture’ source just couldn’t grab it properly anymore. I finally solved it by switching to ‘Window Capture’ for that specific game and then switching back to ‘Game Capture’ after the next OBS update. It felt like trying to tune an old radio with a pair of pliers – frustrating, imprecise, but eventually, it worked.
The key here is knowing when to use ‘Display Capture’ and when to use ‘Game Capture’. If you’re showing a game, especially a fast-paced one, ‘Game Capture’ is your friend. If you’re showing your entire workflow, multiple applications, or something that doesn’t have a clear ‘application’ boundary (like a virtual machine), then ‘Display Capture’ is what you’ll need. And for those tricky situations, ‘Window Capture’ can be a lifesaver, letting you pick a specific window to display.
A word of caution: some games, especially those with aggressive anti-cheat software, can be tricky to capture. They might intentionally obscure themselves from capture sources to prevent cheating. In these cases, you might be forced back to ‘Display Capture’, and you’ll need to be extra careful about what’s on that monitor.
How to Switch Which Monitor Is Shown on Stream
Switching which monitor is shown on stream is typically done within your streaming software by changing the source you are using for your scene. If you’re using ‘Display Capture’, you’ll go into the source properties and select a different display number. If you’re using ‘Window Capture’, you’ll select a different application window from the dropdown. For ‘Game Capture’, you might need to re-select the game or restart the game and the capture source.

What If My Second Monitor Isn’t Showing Up in Obs?
This is usually a driver issue or a conflict with how Windows is managing your displays. First, try restarting OBS and then your computer. If that doesn’t work, check your graphics card drivers are up to date. Sometimes, unplugging and replugging your monitor can also help Windows re-recognize it. In rare cases, you might need to adjust your display settings in Windows to ensure it’s set to extend displays rather than duplicate.
Can I Switch Monitors Mid-Stream Easily?
Yes, you can. The easiest way is to have multiple sources set up for different monitors or windows and then use OBS’s ‘Scene’ switching to go from a scene showing Monitor 1 to a scene showing Monitor 2, or vice versa. You can assign hotkeys to these scene transitions for quick switching. Alternatively, if you’re using ‘Display Capture’, you can technically change the source properties mid-stream, but this is clunky and not recommended for live broadcasts unless absolutely necessary.
Does Capturing a Whole Monitor Use More Resources?
Generally, yes. Capturing an entire display (Display Capture) requires your system to process and encode everything visible on that screen, including background elements and desktop icons. Game Capture or Window Capture are usually more efficient because they are designed to target and capture only the specific application or window you want, reducing the overall processing load.
Why Does My Game Look Laggy When I Capture My Second Monitor?
This often happens if your second monitor is set to a very high refresh rate or resolution, and your system is struggling to render both the game and the captured display simultaneously. Try lowering the refresh rate of your secondary monitor in Windows display settings, or if you’re using Game Capture, ensure it’s set to capture the game itself rather than the entire monitor it’s on.
| Capture Method | Pros | Cons | My Verdict |
|---|---|---|---|
| Display Capture | Captures everything on a monitor. Great for workflows, multiple apps. | Can be resource-intensive. Can accidentally show unwanted content. | Use only when absolutely necessary. A bit like using a firehose to water a single plant. |
| Game Capture | Highly efficient for games. Targets specific application. | Can be blocked by some anti-cheat software. Less flexible for multi-app scenes. | The go-to for most gaming streams. Solid and reliable. |
| Window Capture | More efficient than Display Capture for single apps. Easy to select specific windows. | Less performant than Game Capture for games. Can break if the window is minimized or closed. | A good middle ground when Game Capture fails or for non-game applications. |
Conclusion
So, there you have it. Figuring out how to switch which monitor is shown on stream boils down to knowing your Windows display numbers and understanding the difference between capturing an entire display versus a specific application. It’s not rocket science, but it’s definitely a point where many new streamers get tripped up, myself included, way back when.
My biggest takeaway after years of this? Double-check your display numbers in Windows *before* you start your stream. Seriously. The sheer amount of time I’ve wasted clicking the wrong box in OBS could have been spent actually talking to my audience. If you’re using a high refresh rate monitor for your game, try the ‘Game Capture’ source first; it’s usually smoother and less taxing on your system. If that fails, then ‘Window Capture’ is your next best bet. ‘Display Capture’ is the last resort, best saved for when you’re showcasing a specific desktop workflow.
Don’t be afraid to experiment with different sources and settings *before* you go live. Set up a test recording, check it back, and see what looks best. The goal is a smooth viewing experience for your audience, and that means making sure they see what you want them to see, not your search history or that half-finished spreadsheet.
