### 1.在Editor中设置分辨率 ###

此种方式只适用于在Editor中运行的情况。方法如下：  
File -> Editor Preference -> play -> Play in New Window中设置

###    2.对导出后的exe文件设置分辨率 ###

在如下目录下添加GameUserSettings.ini文件：  
$EXPORT\_FOLDER%\\WindowsNoEditor\\$GAME\_NAME$\\Saved\\Config\\WindowsNoEditor

GameUserSettings.ini文件内容如下：

[/Script/Engine.GameUserSettings]
    bUseVSync=False
    ResolutionSizeX=1280
    ResolutionSizeY=1024
    LastUserConfirmedResolutionSizeX=1280
    LastUserConfirmedResolutionSizeY=1024
    WindowPosX=-1
    WindowPosY=-1
    bUseDesktopResolutionForFullscreen=False
    FullscreenMode=2
    LastConfirmedFullscreenMode=2
    Version=5

其中  
bUseDesktopResolutionForFullscreen：表示是否要全屏时使用桌面的分辨率

FullscreenMode：  
0-真全屏  
1-假全屏，全屏无边框  
2-非全屏

导出时，exe文件也会在project\\Saved\\StagedBuilds\\WindowsNoEditor中生成，也可以在这个目录下的$GAME\_NAME$\\Saved\\Config\\WindowsNoEditor中放入GameUserSettings.ini

###    3.从C++代码中设置分辨率 ###

void AMyGameMode::BeginPlay()
    {
     
     if(GEngine)
     {
         UGameUserSettings* MyGameSettings = GEngine->GetGameUserSettings();
         MyGameSettings->SetScreenResolution(FIntPoint(1024,768));
         MyGameSettings->SetFullscreenMode(EWindowMode::Fullscreen);
         MyGameSettings->SetVSyncEnabled(true);
         MyGameSettings->ApplySettings();
     }
    }
