RK3399HDMI特殊分辨率输出该怎么设置呢

carter123456 · March 12, 2018, 2:07am

接收端有个比较特殊的分辨率输出，在854*480的样子。应该更改哪个地方呢

技术支持确实不咋样，问问题没人回答。800*480的显示器在Ubuntu下不设置就能显示，Android下没弄出来

我也遇到了同样的问题，经过一个多星期的努力解决了（我的分辨率是480x800）:

亲测有效，我是T4的开发板，只改了system.prop 文件就可以了

我个人感觉单纯改这个不行吧，你应该他适应的分辨率的枚举，然后改system.prop 为默认，这样就对了。要不然他适应的枚举里面没有，你该system.prop 也没有反应的

你好，改完需要编译什么才能生效
