# Let’s Display the Second Screen
On this page, I’ll explain how to display the second screen. You can also try it out with the sample included in the Plugin.
:::caution Dual-screen display does not function in Unity Editor. Please Build and run your app to confirm. :::
## Prerequisites - Setup your Spatial Reality Display, if not, see: Setup [Spatial Reality Display](/Products/Developer-Spatial-Reality-display/en/develop/Setup/SetupSRDisplay.html),[Setup Spatial Reality Display Settings](/Products/Developer-Spatial-Reality-display/en/develop/Setup/SetupSRRuntime.html) - Set up your Unity project installed SRDisplay UnityPlugin, if not, see: [Set up for Unity](/Products/Developer-Spatial-Reality-display/en/develop/Unity/Setup.html)
## How to Display the Second Screen Refer to [Create your simple app "Hello cube!"](/Products/Developer-Spatial-Reality-display/en/develop/Unity/HelloCubeApp.html) to place the SRDisplayManager Prefab. To display the second screen, first call Init2DView() on the SRDisplayManager. Then, obtain SRD2DView. ``` if (_srdManager.Init2DView()) { _srd2DView = _srdManager.SRD2DView; } ``` Use Show(true) to display the second screen. ``` _srd2DView.Show(true); ``` ![](/Products/Developer-Spatial-Reality-display/img/develop/Unity/lets-display-the-second-screen/pic-2dview-l.webp){.img83} To hide the second screen, set it to false. ``` _srd2DView.Show(false); ``` ![](/Products/Developer-Spatial-Reality-display/img/develop/Unity/lets-display-the-second-screen/pic-2dview-none.webp){.img83} In the sample, the F5 key is assigned for toggling display/hide of the second screen.
## How to display the Second Screen in Full Screen You can display the second screen in full screen. ``` _srd2DView.SetFullScreen(true); ``` ![](/Products/Developer-Spatial-Reality-display/img/develop/Unity/lets-display-the-second-screen/pic-2dview-full.webp){.img83} To revert from full screen, use: ``` _srd2DView.SetFullScreen(false); ``` In the sample, you can check this using the F6 key (toggle full screen).
## How to Set Images for the Second Screen You can configure images for display, including left-eye images, right-eye images, and mixed images on the Spatical Reality Display. Set the left-eye image. ``` _srd2DView.SetSourceTexture(SRDTextureType.LeftEye); ``` Set the right-eye image. ``` _srd2DView.SetSourceTexture(SRDTextureType.RightEye); ``` Set the mixed image. ``` _srd2DView.SetSourceTexture(SRDTextureType.SideBySide); ``` ELF-SR2: ![](/Products/Developer-Spatial-Reality-display/img/develop/Unity/lets-display-the-second-screen/pic-2dview-sbs-sr2.webp){.img83} ELF-SR1: ![](/Products/Developer-Spatial-Reality-display/img/develop/Unity/lets-display-the-second-screen/pic-2dview-sbs-sr1.webp){.img83} In the sample, you can switch image settings using the F7 key.
