iPad 2上带有HDMI适配器的黑条 [英] Black bars with HDMI Adapter on iPad 2

问题描述

我的应用程序支持HDMI输出。

My app supports HDMI Output.

我询问了电视分辨率的代码，获得了1920 x 1080像素

I asked the code for the resolution of the TV and got 1920 x 1080 px for

externalScreen.bounds

好的，一切精细。我设置了我的观点并在电视上试了...

OK, everything fine. I've setup my views and tried it on the TV ...

但是 黑条在屏幕的底部/顶部/侧面虽然电视被正确检测为1920 x 1080并且我的视图也正确设置了？

BUT: There were black bars on the bottom / top / sides of the screen though the TV was detected correctly as 1920 x 1080 and my view is also set up correctly?

为什么格式错误？

PS当我镜像主屏​​幕时，它还会显示条形图，当我用Youtube应用程序观看视频时，黑条消失了吗？

P.S. When I mirror the home screen, it also shows the bars, when I watch a video with the Youtube App, the black bars disappear?

感谢您的帮助！

更新：

好的，虽然我在控制台中输出了这个输出：

OK, although I got this output in my console:

A new screen got connected: <UIScreen: 0x3439a0; bounds = {{0, 0}, {1920, 1080}}; mode = <UIScreenMode: 0x345240; size = 1920.000000 x 1080.000000>>

...我仍然得到黑框。我用 CGRectMake（0.0f，0.0f，1920.0f，1080.0f）初始化我的视图用于测试目的。

... I still get the black frame. I init my view with CGRectMake(0.0f,0.0f,1920.0f,1080.0f) for test purposes.

这是我在屏幕上可以看到的视图（注意黑条）：

This is the view I can see on my screen (note the black bars):

推荐答案
