Window mixed reality(wmr) How to fill the screen without blanks

Unreal said that since 4.21 you can use wmr without steam vr. Everything went well, but there is one problem. The window shown on the monitor is not full. How do I get the monitor to fill the screen without blanks?

I changed the engine source and succeeded in changing the screen.

Can you explain a bit more how you did it? thanks! :slight_smile:

怎么连接windows mixed reality 设备呢。我的4.21版本没有反应呀。谢谢。

add [microsoft window mixed reality] plugin and turn off other VR plugin

Download 4.21 unreal engine source and Modify WindowMixedRealityHMD.cpp as above picture
