The usage scenarios of Multiplicity 4

entertainment

Online streaming games are a popular way of sharing content, but streaming settings are complex and require high-end hardware to achieve. With Multiplicity, you can uninstall non essential applications such as Discord or OBS/xSplit to other devices, but still access them from your gaming console.

• By running applications on other devices to free up resources, your console can only be used for gaming.
• Streaming audio across networks, such as voice chat.
• Use a spare laptop as a second (or third) display to expand your streaming space.

edit

Content creators are aware of the challenges of editing complex video and audio files, as well as the large workstations required for quickly exporting videos. With Multiplicity, you can place the editing device (along with its noisy GPU and fan) in another room and stream it to your computer for editing.

• Stream desktop to any other PC, allowing your laptop to fully utilize all the features of your editing PC while working in another room, avoiding GPU noise.
• Share audio across devices for creative podcasting hosting without using the Internet.
• Hotkeys enable you to easily switch between workloads, helping you export faster.

development

With Multiplicity, you can run Visual Studio or your favorite IDE and stream it into your minimalist settings. Place your powerful and noisy development kit in another room and stream your desktop to your laptop for the best experience, fast compilation, and quiet operation.

• Use Multiplicity to easily switch between desktops, so you can quickly test your applications across multiple versions of Windows.
• Put your IDE on another box and stream it to your preferred PC.
• Use a laptop monitor as another display on your desktop to expand your workspace.

Accessibility

Multiplicity is a virtual KVM that allows you to bind hotkeys to various configuration settings. And by customizing hardware such as larger keyboards, mice, or dedicated input devices, you can map settings to any button to increase functionality.

• Use hotkeys to turn advanced features into one button to switch devices.
• Streaming audio from remote computers to specific devices, allowing multiple users to control sound output.
• Seamless allows you to organize your virtual monitor configuration, turning complex layouts into simple designs.
