Samsung Second Screen vs Apple Sidecar vs Any Display
Short answer
Samsung Second Screen connects a Windows PC to a supported Galaxy Tab wirelessly. If wireless latency or dropouts are the problem, Any Display can connect the computer and tablet directly over USB. It also supports Windows or Mac with either iPad or Android.
Samsung Second Screen is convenient, but its documented PC-to-tablet connection uses Wireless Display. A USB-C to HDMI or DisplayPort cable does not turn a Galaxy Tab into a PC video-input monitor. Any Display uses an app-based USB connection to reduce dependence on Wi-Fi congestion and router conditions for lower latency and a more stable link.
Key points
- Samsung Second Screen: Windows PC to supported Galaxy Tab, wireless
- Apple Sidecar: supported Mac to iPad, Wi-Fi or USB
- Any Display: Windows or Mac to iPad or Android, Wi-Fi or USB

- Can I use an iPad as a second display for Windows?
- Sidecar is for Mac and iPad. A cross-platform app such as Any Display is required to connect a Windows PC to an iPad.
- Can I use a Galaxy Tab as a second display for Mac?
- Samsung Second Screen is documented for Windows PCs and supported Galaxy Tabs. Any Display also connects a Mac to an Android tablet.
- Should I use the built-in feature or Any Display?
- Use the built-in feature when your exact devices are supported and you want the simplest native setup. Use Any Display when the computer and tablet cross ecosystems or you manage several combinations.
- Samsung Second Screen is laggy. Can I use a Galaxy Tab S8 as a wired USB monitor?
- Yes, with Any Display you can connect the PC and Galaxy Tab S8 directly over USB and use it as a second display. Samsung Second Screen itself is wireless-only. A USB-C to HDMI or DisplayPort cable sends video out from the tablet rather than accepting PC video input. Any Display's USB mode reduces dependence on Wi-Fi congestion and router conditions for lower latency and a more stable connection.
