A live show often needs more than one screen. For example, you may want a large confidence monitor in front of you, a Multiview for checking sources, or a separate feed for a vertical stream.
Fortunately, the YoloBox Extreme HDMI outputs make all of that possible.
YoloBox Extreme has two HDMI outputs, and you can program each one independently. In a recent video, PhotoJoseph walks through how he uses them in his own studio. He also explains why his biggest screen does not show the Multiview.
Below, we cover what he shares, from finding the settings to choosing the right output mode for each job.
1. Why Program Out Makes a Strong Confidence Monitor
Behind PhotoJoseph’s desk sits a large confidence monitor. As a result, he can always see exactly what is on air.
He could send the Multiview to that screen. However, he prefers Program Out.
His reason is practical. In a Multiview layout, the program feed sits in one corner. So when he is hosting, switching, and demonstrating products by himself, that smaller window is easy to overlook.
For instance, he might switch from a top-down demo to his talking-head camera and then forget to switch back. With a small program window, he may not notice right away.
A full-screen Program Out feed, on the other hand, solves that problem. Because it sits in his peripheral vision, the on-air shot is always obvious.
Therefore, if you run a solo production, consider giving the program feed its own large screen. That way, you can catch switching mistakes before your audience does.
2. Finding the YoloBox Extreme HDMI Output Settings
You can configure both outputs from the same menu:
1. Tap the gear icon in the top-right corner.
2. Scroll to Output Settings.
3. Tap HDMI Out.
You will see separate settings for HDMI Out 1 and HDMI Out 2. Each output shows its current resolution and the device it is connected to.
You can also change the output frame rate here. Keep in mind that setting a frame rate different from your program frame rate uses extra system resources. PhotoJoseph streams at 30p, so he leaves the output at 30p as well.
3. The Key Rule for Mixing 4K and HD
Before you assign a resolution, note one important limit:
| Output combination | Supported? |
| HD + HD | Yes |
| 4K + HD | Yes |
| 4K + 4K | No |
In other words, only one output can run at 4K at a time.
Moreover, the resolution options depend on what you connect. For example, if HDMI Out 1 feeds a 1080p TV, you will only see HD options. In contrast, if you connect a 4K monitor or 4K recorder, the 4K option becomes available.
In the video, HDMI Out 1 runs at 1080p to a TV. Meanwhile, HDMI Out 2 sends a 4K signal to another YoloBox that handles his Instagram stream.
4. Choosing an Output Mode
Each HDMI output offers the same four modes:
| Output mode | What it sends | Good for |
| Program Out | The live program feed | Confidence monitors, recorders, projectors |
| Multiview Out | A customizable grid of sources | Monitoring all inputs at once |
| Custom Out | Any single source or custom layout | Vertical streams, clean feeds, secondary outputs |
| Mirror Out | The full YoloBox interface | Tutorials, demos, operator displays |
Because each output is set separately, you can mix these modes. For example, one output can show Program Out while the other sends a Custom Out feed.
5. Customizing the Multiview Layout
To start, select Multiview Out. Then tap the small gear icon next to it to open the layout options.
There are many layouts to choose from, such as:
- A simple four-up grid
- Three larger windows plus a smaller four-up group
- A traditional Preview and Program layout
In particular, the Preview and Program layout works well if you use Preview/Program switching mode. In that case, Preview appears on the left, and Program appears on the right.
Besides choosing a layout, you can also pick which input appears in each window. Furthermore, the Multiview can display live stream information.
That said, PhotoJoseph notes that he begins hitting performance limits as he adjusts the layout. So if your production is already demanding, test your Multiview settings before going live.
6. Using Custom Out for a Dedicated Feed
Custom Out, by comparison, lets you send any single video source through an HDMI output. This even includes your custom layouts.
In fact, PhotoJoseph uses this for his Instagram show. First, he sets one output to Custom Out with a vertical layout. Then that feed goes to a second YoloBox, which streams it to Instagram.
As a result, one production can serve two formats. Your main stream stays horizontal, while a separate output carries the vertical version.
Similarly, Custom Out is useful when you need:
- A clean camera feed for an external recorder
- A dedicated layout for a venue screen
- A specific source for a second streaming device
7. Sharing the Interface with Mirror Out
Finally, there is Mirror Out. As the name suggests, it sends a mirror of the entire YoloBox screen through the HDMI output.
PhotoJoseph has used this in past shows. Specifically, he looped the interface back into the YoloBox as an input. Consequently, viewers saw a clean, full-screen view of the interface instead of a top-down camera shot of the device.
So if you create tutorials, product demos, or training content, Mirror Out can make the on-screen steps much easier to follow.
Getting the Most from YoloBox Extreme HDMI Outputs
All in all, the two YoloBox Extreme HDMI outputs give you flexible monitoring and routing options without extra hardware.
Before your next production, therefore, work through these steps:
- First, decide what each screen or device needs to receive.
- Next, open Settings > Output Settings > HDMI Out.
- Then set only one output to 4K if you need 4K.
- Also, match the output frame rate to your program when possible.
- After that, assign Program, Multiview, Custom, or Mirror Out to each output.
- Finally, test the full setup, including audio, before going live.
Above all, for solo creators, PhotoJoseph’s tip is worth remembering: a large Program Out monitor makes it easy to see what your audience sees.
