官方的Raspberry Pi 7"触摸屏显示器(https://www.raspberrypi.org/products/raspberry-pi-touch-display/)在我的Raspberry Pi 2 B上运行的Windows 10 IoT Core上运行得非常好，因为在内部预览中添加了支持(显示和触摸功能)。除了屏幕分辨率。它几乎正确，但屏幕上的所有都略微横向拉伸，这给应用程序UI一种廉价的感觉。最引人注目的是水平拉伸成椭圆形的圆形。
我在config.txt文件中弄乱了值，它声称使用800x480，但没有变化似乎对屏幕有任何影响。是否有办法使分辨率更适合屏幕的800x480尺寸?下面是我正在使用的config.txt。请仔细看;我使用的是每个人都建议的自定义分辨率。我指的是屏幕上的轻微拉伸，而不是完全错误的分辨率。

看起来这是硬件的问题。有多个报告显示该设备的宽高比偏离了10%。
