HarmonyOS 鸿蒙Next ReactNative获取手机分辨率与原生不一致的原因

原生开发获取屏幕分辨率信息得到的分辨率是：1260*2720

代码：

//test
 let displayClass: Array<display.Display> = [];
 display.getAllDisplays((err: BusinessError, data: Array<display.Display>) => {
   displayClass = data;
   const errCode: number = err.code;
   if (errCode) {
     console.error(Failed to obtain all the display objects. Code: ${err.code}, message: ${err.message});
     return;
   }
   console.info('Succeeded in obtaining all the display objects. Data: ’ + JSON.stringify(data));
 });

输出结果:

Succeeded in obtaining all the display objects. Data: [{“id”:0,“name”:“UNKNOWN”,“alive”:true,“state”:2,“refreshRate”:90,“rotation”:0,“width”:1260,“height”:2720,“densityDPI”:520,“orientation”:0,“densityPixels”:3.25,“scaledDensity”:3.25,“xDPI”:444.5,“yDPI”:442.8710021972656,“colorSpaces”:[0,9,10],“hdrFormats”:[1,2,3],“availableWidth”:1260,“availableHeight”:2720}]

而在RN中得到的却是 387 *836

const {width, height} = Dimensions.get(‘window’);

const {screenwidth, screenheight} = Dimensions.get(‘screen’);

<Text>Window Width: {width}</Text>

<Text>Window Height: {height}</Text>

<Text>Screen Width: {screenwidth}</Text>

<Text>Screen Height: {screenheight}</Text>

结果：

window width: 387.6923076923077

window height: 836.9230769230769

screenwidth: undefined

screenheight: undefined

请问是为什么？它们的差异在哪里？
