Although Samsung’s Insights webpage on Wireless DeX says “latest devices”, currently, the Samsung Galaxy S21 series running One UI 3.1 only seems to support it. To get it, update the DeX client on the PC to the latest version. You can download it here too. Now, follow the steps below:
- Open the DeX shortcut on the Phone and Select the “DeX on PC” option.
- From the list of devices available(if many), choose one and select “Start Now”.
- After accepting the Prompt on PC, you can start using it wirelessly.
Note: If you have “Link to Windows”(Samsung’s Microsoft Your Phone-like soln) connected, this won’t work. Be sure to turn it off.
The report also says that the resolution is limited to 1080p. As for performance, the feature is reportedly working fine on PC and not as bad as when connecting to TV. One more thing to note, the S-Pen isn’t reportedly seamless.
Apparently, you can’t sketch drawings on Samsung Notes using S-Pen(on your device) when opened on the PC.
Samsung DeX is a software platform to make your smartphone into a desktop computing machine. It initially required a DeX Station/Pad as an accessory. Later, it got reduced into an HDMI adapter. This made users connect to external monitors/displays and enjoy a desktop experience.
In 2019, it finally brought the DeX for PC however required a cable. With the launch of Galaxy Note 20 last year, it finally expanded the horizon wirelessly. As long as Smart TVs with Miracast support and Phone are connected to the Same Wi-Fi, users were able to use DeX wirelessly.
Anyway, the feature is finally supported for PC and you can expect the compatibility to extend to many devices like Galaxy Tab S7 which recently got the One UI 3.1 update.
