[0066] 115、 主机根据总线复位请求, 读取与主机连接的通道的总线对应的存储器中 的显示窗口的 EDID信息。
[0067] 具体的, 显示器与每台主机之间可以通过总线连接, 相应的, 在主机对应的总 线上可以设置主机对应的存储器, 显示器生成显示窗口的 EDID信息后, 可以将 EDID信息存储在与显示窗口对应的主机连接的总线的存储器中, 这里的存储方 式为覆盖形式, 即对存储器中的 EDID信息进行更新, 显示器发起总线复位请求 后, 主机即可根据总线复位请求, 从与自身连接的总线对应的存储器中重新读 取 EDID信息, 以根据 EDID信息向显示器提供与 EDID信息匹配的图像。
[0068] 实际应用中, 通道的总线通常可以为显示数据通道 DDC (Display Data Channel , 检测 DDC) 总线, DDC是建立在主机和显示器之间的信息通道, 可以将显示 器的数据输给主机。 可选的, 为了提高传输效率, 在将 EDID信息存储至存储器 中之前, 显示器可以利用 EDID编译模块, 对 EDID信息进行编译, 获得 EDID字 段, 将 EDID字段存储至相应的存储器中。 相应的, 相应的, 主机可以解析 EDID 信息中的分辨率字段, 并根据分辨率字段中的第一字节和第二字节, 输出相应 的图像。
[0069] 通过本实施方式无需专门建立用于传输显示屏幕状态的通道, 在提高显示效果 的基础上, 进一步节省成本, 并且能够提高处理效率。
[0070] 本实施例提供的显示处理方法, 显示器获取显示窗口的行方向分辨率和列方向 分辨率后, 根据所述显示器当前的状态, 将显示窗口的行方向分辨率和列方向 分辨率编译至该显示窗口对应的 EDID信息中的分辨率字段中对应的字节, 显示 窗口对应的主机读取显示窗口的 EDID信息, 根据 EDID信息中分辨率字段中不同 字节的大小比较结果, 向显示器提供相应的图像进行显示, 从而实现根据显示 器的当前状态对主机提供的图像进行动态调整和更新, 使主机提供的图像与显 示窗口匹配, 避免因不匹配导致的图像显示质量下降的问题, 提高显示效果和 稳定性。

[0110] 通过本实施方式无需专门建立用于传输显示屏幕状态的通道, 在提高显示效果 的基础上, 进一步节省成本, 并且能够提高处理效率。
[0111] 本实施例提供的显示处理系统, 显示器获取显示窗口的行方向分辨率和列方向 分辨率后, 根据所述显示器当前的状态, 将显示窗口的行方向分辨率和列方向 分辨率编译至该显示窗口对应的 EDID信息中的分辨率字段中对应的字节, 显示 窗口对应的主机读取显示窗口的 EDID信息, 根据 EDID信息中分辨率字段中不同 字节的大小比较结果, 向显示器提供相应的图像进行显示, 从而实现根据显示 器的当前状态对主机提供的图像进行动态调整和更新, 使主机提供的图像与显 示窗口匹配, 避免因不匹配导致的图像显示质量下降的问题, 提高显示效果和 稳定性。
