树莓派4 HDMI显示

树莓派4直接上电，试过诸多参数，HDMI在我的显示器上（LG27M35）无法显示。

但是改电脑USB3.0供电，HDMI工作正常。

相关参数如下：

# uncomment if hdmi display is not detected and composite is being output hdmi_force_hotplug=1   # uncomment to force a specific HDMI mode (this will force VGA) hdmi_group=1 hdmi_mode=16     # uncomment to force a HDMI mode rather than DVI. This can make audio work in # DMT (computer monitor) modes hdmi_drive=2   # uncomment to increase signal to HDMI, if you have interference, blanking, or # no display config_hdmi_boost=4
