Android 12 修改分辨率失败

Chip Platform Rockchip
1

主板为ROC-RK3588S-PC
1、问题1：修改以下代码，修改分辨率为1920*1200，重新烧录固件后，分辨率还是没有变动；请给出具体的解决方案，需要具体到修改代码的那一行，谢谢！

以下代码，是修改分辨率为19201200

2、问题2：执行以下代码，隐藏状态栏
 默认隐藏状态栏4.1.1. 代码修改的方式

  • 修改内容如下

重新烧录固件后，状态栏没有隐藏；请给出具体的解决方案，需要具体到修改代码的那一行，谢谢！

  1. 什么分辨率？HDMI的分辨率，还是系统的wm size ？
  2. 改错地方了，修改 frameworks/base/packages/SettingsProvider/res/values/firefly_defaults.xml:9: true

  1. 什么分辨率？HDMI的分辨率，还是系统的wm size ？
  2. 改错地方了，修改 frameworks/base/packages/Sett …

问题1，里面的代码，我在3399ProC上面修改后，分辨率是成功的
HDMI的分辨率，和系统的wm size，这2个怎么改的，你都回复我下，谢谢

  2. 参考 4K@25
    uboot

这段代码修改后，重新烧录固件，我用你们FireflyApi2Demo软件里面的屏幕信息查看，分辨率还是1920*1080；
还有哪里可以修改分辨率的，修改分辨率后，用FireflyApi2Demo软件查看屏幕信息，如果成功，就是我想要的，请给出详细的修改方案，谢谢，拜托！

  1. HDMI分辨率和系统分辨率是不一样的概念
    2.系统分辨率，参考
device/rockchip/rk3588/roc_rk3588s_pc/roc_rk3588s_pc.mk:53:PRODUCT_PROPERTY_OVERRIDES += persist.vendor.framebuffer.main=1920x1080@60

3.如果还不行，定制化需求，可以联系商务 sales@t-firefly.com
