What you need to know

  • The Galaxy Tab S7 can now act as a second screen for select Windows 10 PCs.
  • The new feature is rolling out with the One UI 3.0 update.
  • The feature requires a WiDi-capable PC running Windows 10 version 2004 or later.

The Samsung Galaxy Tab S7 and Galaxy Tab S7+ already top our sister site Android Central's list of the best Android Tablets. Now, with the rollout of One UI 3.0, the tablets are even better options for people who also have a Windows 10 PC. One of the many features that comes with the latest update is Second Screen, which allows you to duplicate or extend the display of a Windows 10 PC to the Galaxy Tab S7 or S7+.

The feature is a bit like Apple's Sidecar, allowing you to use a tablet you already own as a second display instead of having to buy a dedicated portable monitor. Like using Windows 10 with other monitors, you can either duplicate your display to your tablet or extend it as a second screen. There isn't an option to use the tablet as your only display, though that option is more useful when using PCs with a presentation display or TV.

To use Second Screen, you have to have a Galaxy Tab S7 or S7+ running One UI 3.0 and a supported Windows 10 PC. Your PC needs to be WiDi (Wireless Display) capable and running Windows 10 version 2004, also known as the Windows 10 May 2020 Update, or later. There are PCs that meet these requirements that aren't from Samsung, but the company highlights that the Galaxy Book Flex2, Galaxy Book Flex2 5G, Galaxy Book Flex, and Galaxy Book Flex alpha all work with the Second Screen feature.

If you don't have one of these Galaxy tablets, you can also check out spacedesk, which lets you use your Android tablet and many other types of devices as an additional monitor.

  • That's great, but too bad Samsung can't get their act together and be consistent about the OS/UI updates they push out. My older Note 10+ got the Android 11 (R) and OneUI 3.0 update several days ago, while my newer Tab S7+ still can't get either.
