Windows Latest discovered a post on the Chromium Gerrit, according to which Microsoft appears to be working on a "dual-screen emulator" that targets the open-source Chromium browser and users will be able to enable it via an experimental flag.
The news about the emulator is not unexpected, as more devices are appearing on the market. What is notable, however, is the fact that the emulator is only aimed at mobile devices.
As we know, so far the emulator supports the Galaxy Fold and Surface Duo, which are scheduled to be released later this year. However, more devices are likely to be added in the future. Meanwhile, Microsoft has already released the Windows 10X emulator for the dual-screen Surface Neo.
Microsoft's new emulator includes some changes, such as support for different orientation settings for dual- screen, when in portrait or landscape mode.
Additionally, new controls have been added to extend the browser's UI from single to dual screens. If a device has a hinge in dual-screen mode, it will also appear in the emulator. Microsoft has also released screenshots showing what the dual-screen device emulation feature will look like.
The original idea for the emulator is to be used by developers so they can optimize websites for dual-screen devices. However, a regular user could also use it to see how a page would appear on dual-screen devices.
It's likely that the new dual-screen emulation feature will arrive in Edge Chromium after its development is complete. Since Edge Chromium was created, Microsoft has been very active in the Chromium project. Earlier this year, it added a feature that helps Chromium (and Chrome) reduce battery.
