iPad Mirroring使用2个屏幕，它支持1080分辨率吗？ [英] iPad Mirroring using 2 screens, does it support 1080 resolution?

问题描述

2.5年的mac和iOS开发，我还没有找到答案。

2.5 years of mac and iOS development and i haven't found an answer to something.

我正在开发一个利用iOS 5.0和Apple TV播放的项目，在iPad上显示一个UIScreen，在Apple TV上显示一个。我有2个独立的视图控制器，它们分别显示在每个控制器上。

I'm working on a project utilizing iOS 5.0 and apple TV's airplay to display one UIScreen on the iPad and a separate one on my Apple TV. I have 2 separate view controllers and they display fine on each respectively.

问题在于苹果电视屏幕尺寸为720p而不是1080p。所以我得到了一个显示1280 X 720的边框视图控制器，而不是1920 x 1080的全屏显示。效果是我的视图控制器裁剪不缩放。

The issue is that the apple tv screen size returns at 720p not 1080p. So i get a bordered view controller at 1280 X 720 displayed and not a full screen representation of 1920 x 1080. The effect is my view controller is cropped not scaled.

我尝试了一些顽皮的事情，比如更改UIScreen的屏幕边界和视图控制器边界，但这不起作用。

I tried the naughty things like changing screen bounds of the UIScreen and the view controller bounds but that doesn't work.

简单地说：

iOS 5是否支持全屏1080p视图控制器显示？如果是这样你是怎么做到的？

Does iOS 5 support a full screen 1080p view controller to be displayed? if so how did you do it?

编辑：

所以修改了一个问题，如果只能显示720p那么我该如何获得应用程序显示其视图控制器全屏而不是裁剪/ letterboxed？

So the question is modified that if only 720p is possible to display then how do i get the app to display its view controller fullscreen and not cropped/letterboxed?

推荐答案

Apple TV仅支持720p，但应注意数字AV适配器支持1080p（1920x1080）。我怀疑如果下一代Apple TV发布，它将支持1080p并可能支持在AirPlay上显示它。

Apple TV only supports 720p, but it should be noted that the Digital AV Adapter supports 1080p (1920x1080). I suspect that if a next gen Apple TV is released, it will support 1080p and may support displaying it over AirPlay.

除了这个问题，我面临的问题与你 - 当我在三星电视上通过数字AV适配器和Airplay进行显示时，我正试着弄清楚为什么我的视图会被插入。我终于弄清楚我的电视是如何配置我正在使用的端口的问题。当我找到相关输入的Just Scan选项时，它解决了问题，我得到了一个完美的边到边图像。使用数字AV适配器的1080p输出很漂亮，我有很多有趣的创建一个利用它的应用程序。

That issue aside, I faced exactly the same problem as you - I was pulling my hair out trying to figure out why my view was inset when displaying both via the Digital AV Adapter and over Airplay on my Samsung TV. I finally figured out that it was an issue with how my TV was configured for the ports that I was using. When I found the "Just Scan" option for the relevant inputs, it solved the problem and I got a perfect edge-to-edge image. The 1080p output using the Digital AV Adapter is gorgeous and I'm having lots of funny creating an app that leverages it.

在调查的过程中，我了解了UIScreen的新iOS 5.0 overscanCompensation属性（http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UIScreen_Class/Reference/UIScreen.html）。这不是我困难的根源，但您可能想要使用它的设置来查看它是否解决了您的问题。

In the process of investigating, I learned about the new iOS 5.0 overscanCompensation property of UIScreen (http://developer.apple.com/library/IOs/#documentation/UIKit/Reference/UIScreen_Class/Reference/UIScreen.html). This was not the source of my difficulties, but you might want to play with it's settings to see if it solves your issue.
