==Article purpose== 本文旨在指定在HDMI <sup>®</sup><ref>[https://www.hdmi.org HDMI (High-Definition Multimedia Interface)]</ref> 监视器(或电视)上显示的内容 通过HDMI电缆连接到STMicroelectronics板上(在以下说明的不同用例中)。 本文还介绍了如何获取设备支持的HDMI监视器(或电视)的视频模式(分辨率和刷新频率),如何对其进行测试以及最终如何选择。 ==Prerequisites== 显然,STMicroelectronics板必须具有HDMI连接器,这是以下情况的情况: {{UpdateNeededForNewBoard|Point to the HDMI connector (if any) of the new

* 如果该板同时具有DSI显示器和HDMI监视器,则Wayland背景层仅显示在这些显示器之一上(请参阅下面的“规则”)。 * [[#HDMI-unplugged|'''HDMI unplugged''']]: 如果在板卡启动之前没有HDMI监视器连接到板上,并且如果DSI显示器连接到板上,则Wayland背景层显示在 DSI显示。 * [[#HDMI-cold-plug|'''HDMI cold-plug''']]: 如果在板子启动之前将HDMI监视器连接到板上,则Wayland背景层会显示在此HDMI监视器上。 * [[#HDMI-hot-plug|'''HDMI hot-plug''']]: 如果在板卡启动后将HDMI监视器连接到板卡,则Wayland / Weston会自动检测到此插头。 演示启动器窗口不会自动放大:关闭并再次打开它以使其在HDMI监视器上全屏显示。 *

通常,HDMI监视器(或电视)提供几种视频模式(分辨率和刷新频率),平台可能不完全支持这些模式。 如果使用“ HDMI冷插”或“ HDMI热插”,则选择平台支持的HDMI监视器提供的第一种视频模式。 要更改默认情况下选择的此视频模式,应检索,可选地测试HDMI监视器提供的和平台支持的所有视频模式,最后在“ weston.ini”配置文件中设置<ref>[[Wayland Weston overview#Configuration|How to configure Weston]]</ref>. 让我们假设DSI显示器和HDMI监视器连接到电路板,并且Wayland背景显示在HDMI监视器上。 * 借助 [[DRM KMS overview#modetest (DRM/KMS test tool) | modetest]]命令(参见 [[#How to get all the video modes supported by the HDMI monitor|below]] 如何获取HDMI显示器支持的所有视频模式,无论平台是否支持),获取HDMI监视器提供的、平台支持的所有视频模式。 {{Board$}} modetest -M stm <pre> Encoders: id crtc type possible crtcs possible clones 28 33
