(2)手持设备10在与显示设备20通过转接线105连接开始后，手持设备10检测到某个预设条件后执行S305至307，该某个预设条件包括：手持设备10从USB接口104获取到显示设备20的一个寄存器或存储器上的一个或多个参数值。例如，手持设备10从USB接口104获取到至少两个参数值，一个参数值表示显示设备20的源端口是VGA端口，另一个参数值表示手持设备所连接的端口1233是HDMI3端口。或者，手持设备10从USB接口104获取到至少一个参数值，该参数值表示显示设备的源端口不是该端口1233。或者，
(3)手持设备10在与显示设备20通过转接线105连接后，手持设备10检测到用户在手持设备10上的一个或多个操作后执行S305至307(例如，用户在手持设备10的投屏功能界面点击 了投屏按钮，该投屏功能界面是手持设备10在与显示设备20通过转接线105连接后自动出现的。或者，用户在手持设备10中通过点击操作进入投屏功能界面，然后用户在投屏功能界面点击了投屏按钮)。
应理解：可选的，S303也可以理解为触发S305和S307的前提条件。在这种情况下：手持设备10可能执行的过程包括：
手持设备10检测到与显示设备20通过转接线105连接之后，手持设备执行S305至S307。其中，对于S305：手持设备10确定所述显示设备的显示内容的源端口不是端口1233，包括：
手持设备10通过通过所述USB接口获取的参数值确定所述源端口不是端口1233。例如，手持设备10从USB接口104获取到显示设备20的一个寄存器或存储器上的一个或多个参数值。
其中，一种可能实现的方式：手持设备10从USB接口104获取到至少两个参数值，一个参数值表示显示设备20的源端口是VGA端口，另一个参数值表示手持设备所连接的端口1233是HDMI3端口。例如，手持设备10通过辅助通道(Auxiliary Channel，AUX CH)获取显示设备20的显示端口配置数据(DisplayPort Configuration Data，DPCP)，通过DPCP获取显示设备20的端口1233的类型；手持设备10通过AUX CH获取显示设备20的源端口。
另一种可能实现的方式：手持设备10从USB接口104获取到至少一个参数值，该参数值表示显示设备的源端口不是该端口1233。例如，手持设备10通过AUX CH获取到该参数值，该参数值表示显示设备的源端口不是该端口1233。
所述自动通过所述红外遥控应用将所述源端口切换为端口1233，包括：
手持设备10自动启动所述红外遥控应用，并通过所述红外遥控应用触发所述手持设备10发送红外指令给所述显示设备，所述红外指令用于指示所述显示设备将所述源端口切换为端口1233，该端口1233的标识是手持设备1233通过USB接口104从显示设备20获取的。例如，该红外指令为通道选择指令，该通道选择指令用于指示所述显示设备20将所述源端口切换为端口1233。显示设备20根据该通道选择指令将显示设备的源端口切换为端口1233。通过采用上述方案，可避免用户手动点击红外遥控应用的操作。应理解：源端口也称为输入源端口，其可以理解为显示设备当前显示内容的来源端口。
该红外遥控应用的遥控码是由手持设备10根据显示设备20的品牌参数或型号参数中的至少一种自动设置的，显示设备20的品牌参数或型号参数是由手持设备10通过USB接口104从显示设备20获取的。应理解：红外遥控应用可以是手持设备出厂时预装在手持设备中的应用程序，也可以是用户自己下载并安装在手持设备中的应用程序。我们假设手持设备10首次与显示设备20通过转接线连接，且手持设备内部的红外遥控应用中预设的遥控码是三星型号1的电视或者预设的遥控码为空，显示设备20是松下TH-65AX800C电视。手持设备10的USB接口104的类型为USB Type-C接口，转接线的类型为USB Type-C转HDMI为例进行描述。手持设备10的USB Type-C接口通过转接线连接到显示设备的一个端口(HDMI 3端口)之后，手持设备10利用USB Power Delivery协议识别到转接线105是显示端口(DisplayPort，DP)设备，手持设备10启动DP模块，手持设备10通过AUX CH获取显示设备20的扩展显示标识数据(Extended display identification data，EDID)信息，通过EDID信息获取到显示设备的品牌参数、型号参数、分辨率等信息。显示设备的EDID信息存储在存储器(例如，PROM或EEPROM)。EDID的格式如图5所示。手持设备10通过EDID信息获取品牌参数和/或型号参数，自动设置红外遥控应用的遥控码，从而该红外遥控应用可以遥控显示设备20。通过采用上述方案，可避免用户手动设置红外遥控应用的操作，当手持设备10确定预设的遥控码与显示设备 20的型号相同的时候，就不需要执行自动设置的动作了。
对于S307，所述手持设备10经由所述USB接口104，所述转接线105以及所述端口1233将所述手持设备10的待显示内容发送至所述显示设备20，所述显示设备20显示所述待显示内容。所述待显示内容包括所述手持设备的显示器显示的内容，或者，所述手持设备的一个预设的用户界面(例如，一个具有一个或多个应用图标的交互界面)。
可选的，如图6所示：在一种可能的实施方式中，该过程300还包括：S308，在所述手持设备10确定所述显示设备20预设的源端口不是所述端口1233之前，所述手持设备10检测到该显示设备20处于待机状态，自动启动该红外遥控应用，并发送一个红外唤醒指令。显示设备20收到红外唤醒指令之后，显示设备20从待机状态进入正常工作状态。应理解：S308可以在S303之前执行，或者S308可以在S303之后且在S305之前执行。
在一种可能的实施方式中，该过程300还包括：S309，在所述手持设备10确定所述显示设备20预设的源端口不是所述端口1233之前，所述手持设备10自动启动该红外遥控应用，并发送至少一个红外唤醒指令。显示设备20收到红外唤醒指令之后，如果显示设备20处于待机状态，则显示设备20从待机状态进入正常工作状态；如果显示设备20处于正常工作状态，则不响应该红外唤醒指令。应理解：S309可以在S303之前执行，或者S308可以在S303之后且在S305之前执行。
采用上述方案，能够实现手持设备自动切换显示设备的源端口，并将手持设备上的待显示内容显示在显示设备的屏幕上。为用户提供便利且大大缩短将手持设备上的待显示内容显示在显示设备的屏幕上的时间，还避免了用户到处找不到遥控器的烦恼。
