How to resize HoloLens 2D application window size via code

Sadev Kalubowila 10

I want to customize windows size of my 2D HoloLens UWP application. I have tried below code in my .NET application. This doesn't work in HoloLens, but it works in Windows PC.

ApplicationView.PreferredLaunchViewSize = new Windows.Foundation.Size(950, 800);
ApplicationView.PreferredLaunchWindowingMode = ApplicationViewWindowingMode.PreferredLaunchViewSize;

How to resize the 2D UWP HoloLens Application's window size?

Hello, Welcome to Microsoft Q&A,

Windows Mixed Reality runs all 2D apps at a fixed resolution and DPI that equates to 853x480 effective pixels, regardless of window size, so this is what you should design for. Please refer to Updating 2D UWP apps for Windows Mixed Reality - Mixed Reality | Microsoft Learn for more information.

Hi Ying, Thanks for the reply. To make it clear, can't we change that fixed resolution to the custom resolution? isn't it possible? And what does "Windows Mixed Reality doesn't support 2D live tiles." mean that mentioned in the reference you have provided ?
