Which system do you use? Android, Ubuntu, OOWOW or others?

Android

Which version of system do you use? Please provide the version of the system here:

VIM3_Pie_V210908

Please describe your issue below:

1、Vim3开发板通过HDMI连接分辨率为1024x768的显示屏；
2、开发板分辨率设置为1024x768；
3、adb连接开发板，adb shell进入命令行，wm size 1024x768，density设置为160
4、横屏显示正常，旋转屏幕为竖屏时显示异常

竖屏情况下高不能适配屏幕高度，怎样才能使竖屏显示正常呢？

wm size是UI的分辨率，要想改变HDMI的分辨率需要在Droid Settings->Display->Screen resolution->Display Mode中选择

Display Mode中设置的也是1024x768，如下图：

如果我不通过wm size设置分辨率，只在Display Mode中设置的话，屏幕上的图标显示是变形的（正常情况下图标是正方形，现在是矩形），如下图所示：

你试下最新的固件，这个分辨率的显示器我这里没有

我重新烧录了v231122这个版本的固件，上面描述的问题依然存在。

我们为了兼容MIPI和HDMI同显，将不是默认分辨率旋转后居中显示，Amlogic平台都是这样的

我尝试将默认的wm size修改成1024x768的试试

好的，辛苦了，有结果了麻烦通知一下，谢谢。
