Win 10 IoT 和 R Pi Official 7 的屏幕分辨率问题触摸屏 [英] Screen resolution issues with Win 10 IoT and R Pi Official 7" touchscreen
问题描述
官方 Raspberry Pi 7" 触摸屏显示器 (https://www.raspberrypi.org/products/raspberry-pi-touch-display/) 与在我的 Raspberry Pi 2 B 上运行的 Windows 10 IoT Core 配合得非常好，因为在 Insider Preview 中重新添加了支持(显示和触摸功能).除了屏幕分辨率.它几乎是正确的，但是屏幕上的所有内容看起来都轻微水平拉伸，这给应用 UI 带来廉价感.最值得注意的是圆形被水平拉伸成一个椭圆形.
The official Raspberry Pi 7" Touchscreen Display (https://www.raspberrypi.org/products/raspberry-pi-touch-display/) works really well with Windows 10 IoT Core running on my Raspberry Pi 2 B since support was added back in an Insider Preview (display and touch are functional). Except for the screen resolution. It is almost right, but everything on the screen appears slightly stretched horizontally which gives the app UI a cheap feel. Most notable are circular shapes that are stretched horizontally into an ellipse shape.
我弄乱了 config.txt 文件中的值，该文件声称使用了 800x480，但似乎没有任何更改对屏幕产生任何影响.有什么办法可以使分辨率更好地适应屏幕的 800x480 尺寸?下面是我正在使用的 config.txt.请仔细看；我正在使用每个人都建议的自定义分辨率.我指的是屏幕的轻微拉伸，而不是完全错误的分辨率.
I've messed around with values in the config.txt file, which claims to be using 800x480, but no changes seem to have any effect on the screen. Is there any way to make the resolution fit the 800x480 dimensions of the screen better? Below is the config.txt I am using. Please look closely; I am using the custom resolution that everyone suggests. What I'm referring to is a slight stretch in the screen, not a completely incorrect resolution.

推荐答案
看起来这是硬件问题.有多个报告称该设备的纵横比降低了约 10%.
It looks like this is an issue with the hardware. There are multiple reports of the aspect ratio of this device being off by about 10%.
