Win 10 IoT和R Pi Official 7"触摸屏的屏幕分辨率问题

Question

官方Raspberry Pi 7"触摸屏显示器(https://www.raspberrypi.org/products/raspberry-pi-touch-display/)与我的Raspberry Pi 2 B上运行的Windows 10 IoT Core非常配合,因为支持已添加回来在内幕预览中(显示和触摸功能正常).除了屏幕分辨率.它几乎是正确的,但屏幕上的所有内容都呈现水平略微拉伸,这使得应用UI具有便宜的感觉.最值得注意的是水平拉伸的圆形形状成椭圆形.

我已经搞乱了config.txt文件中的值,声称正在使用800x480,但没有任何更改似乎对屏幕有任何影响.有没有办法让分辨率800x480更好地适应屏幕的尺寸？以下是config.txt我正在使用的.请仔细看看; 我正在使用每个人都建议的自定义分辨率.我指的是屏幕上的轻微伸展,而不是完全不正确的分辨率.

看起来这是硬件问题。有多个报告称该设备的长宽比下降了约 10%。
