When you’re planning visuals for an event, it’s tempting to keep things simple and just run everything from one laptop—PowerPoint slides, videos, web demos, even music playback. But in live events, “simple” can quickly turn into “stressful” when that single device fails or starts behaving unpredictably. Over the years, we’ve seen everything from delayed CEO keynotes to stretched logos on massive LED walls—all because of a single-laptop setup.
Why the Feed Method Matters
LED walls are optimized for one resolution at a time. Each application you switch between can output a different resolution or aspect ratio, forcing the wall to resync. Even a split-second blackout can feel like an eternity when a roomful of attendees is watching. Choosing the right feed method can be the difference between a seamless show and a mid-event scramble.
| Method | Pros | Cons / Risks | Best Use Cases |
|---|---|---|---|
| Single Laptop – Multiple Apps | Cheapest option (only one device) Simple setup at first glance |
App switching changes resolutions/aspect ratios Higher crash risk No backup if the laptop fails Delays or blackouts when switching apps |
Small, informal events where visual quality is not critical |
| Single Laptop – Single Dedicated App | Simple configuration Fewer resolution changes Lower crash risk than multiple apps |
Still no redundancy Limited flexibility for adding content sources later |
Small events or single-purpose content playback |
| Multiple Laptops – One per Content Type | Stable output per source Faster switching with a video switcher Reduces CPU load per laptop |
Requires more hardware Slightly more complex wiring/setup |
Corporate events, conferences, trade shows |
| Media Player / Built-In LED Processor | Plays preloaded loops or signage without extra hardware Very reliable for static content |
Not ideal for live or interactive changes Limited to prepared content |
Digital signage, product booths, static video walls |
| Multiple Sources via Video Switcher/Scaler | Professional standard Handles scaling & aspect ratios Seamless transitions Operator can react instantly to issues |
Higher rental cost Requires trained operator |
High-profile events, multi-source shows, live broadcasts |
Key Takeaways
For casual or single-use events, a dedicated single-app laptop might be enough—but only if glitches won’t cause major issues.
For anything high-profile or multi-source, a video switcher/scaler with multiple dedicated laptops is the industry gold standard.
Static installations like product booths or signage can be handled by a simple media player.
A Real-World Example
Last year at a trade show, a client insisted on running PowerPoint, VLC video playback, and a browser demo all on one laptop. Midway through the keynote, the laptop froze. Because we had a switcher ready, we quickly switched to a backup source and saved the presentation without the audience noticing. It’s moments like these that prove the value of proper planning and equipment.
Conclusion
Running multiple applications on one laptop may save a little effort upfront, but it can cost you credibility—and potentially your event—if things go wrong. Choosing the right feed method, backed by the right gear and expertise, ensures your content shines as intended.
